OBS Studio now supports NVIDIA NVENC AV1 encoder on GeForce RTX 40 GPUs

A popular streaming and recording software will now benefit from RTX 40 powerful AV1 encoding hardware.  

The latest release of OBS brings support for AV1 recording with NVIDIA NVENC encoder on RTX 40 GPUs. The RTX 4090, the only model available which based on Ada architecture, has dual AV1 encoders. This is an eight generation NVENC encoder that officially provides twice as fast H.265 encoding and support for AV1.

The AV1 encoding option now shows up for recording, but it is not yet available for streaming because no platform supports this format.

The AV1 encoding currently only works with NV12 (8-bit, 4:2:0) and P010 (10-bit, 4:2:0) color modes. The AV1 encoding requires more powerful hardware than H.264 and H.265. The main advantage of AV1 encoding is no licensing fee, which is not the case with HEVC encoders.

According to independent testing, AV1 is up to 30% more efficient than H.265 while delivering better quality images. For this reason, the GPU market has every reason to pursue AV1 encoding and decoding, which should eventually lead to higher popularity of free video formats. The AV1 encoding is also supported by Intel Arc GPUs, even on the A380 which costs 11 times less than RTX 4090.

28.1 Changes

  • Added NVENC AV1 hardware encoder on Windows [Jim]
    • Currently only works with the NV12 (OBS default) and P010 color formats
    • Currently does not support the “rescale” feature in advanced output mode
    • Only available for RTX 40 Series video cards from NVIDIA
  • Updated NVENC presets [Jim]
    • Presets have been split into 3 different settings: Preset, Tuning, and Multipass mode
    • Presets are now P1-P7, lower numbers being lower quality, higher numbers being higher quality. Note that higher presets may incur higher GPU usage which could impact the performance of games running simultaneously with OBS. The number of simultaneous NVENC encoding sessions may be lower when using the highest presets. OBS will automatically map your current NVENC settings to the closest preset when upgrading.
    • Tuning is used to determine whether to prioritize latency or quality. It has three settings: High Quality, Low Latency, and Ultra Low Latency.
    • Multipass Mode is used to determine whether a second pass is used in encoding, and has three settings: Disabled, Quarter Resolution, and Full Resolution. Enabling this will give higher quality at the cost of more GPU resource usage.
  • Fixed a bug where Direct3D 9 games stopped capturing properly with game capture on Windows 11 22h3 [Rodney]
  • Moved “Always on Top” to the View menu [gxalpha]
  • You can now select a specific source for the Virtual Camera [chippydip]
  • Fixed a crash on resolution change of Windows Virtual Camera [Jim]
  • Fixed a Discord crash with Windows Virtual Camera [Jim]
  • Fixed crashes with macOS applications loading the virtual camera [PatTheMav]
  • Fixed Steam version launching x86_64 version on Apple Silicon devices [Rodney]
  • Fixed Stats widget appearance issues [tytan652]
  • Fixed Blend Method in Studio Mode [rcdrone]
  • Fixed case where video capture is darkened when both luma wipe and scale filtering are set [rcdrone]

About This Guide

The objective of this guide is to help you understand how to use the NVIDIA encoder, NVENC, in OBS. We have simplified some of the concepts to make this accessible to a wider audience. If you think we can improve any part of this guide or find any issues or mistakes, please post below and we will be happy to update it.

Bitrate, Resolution and Framerate

Encoding is all about compressing images. The smaller the size of the image, the less we must compress it and the more quality it keeps. While the same applies for framerate, a viewer can really notice a drop in FPS but not so much in resolution, so we will always try to stream at 60 FPS.

First, run a speed test to determine your upload speed (e.g. Speed Test). We want to use around 75% of your upload speed, as the game and other programs such as Discord will also fight for bandwidth.

Then, we will determine the resolution and FPS that we can use for such bitrate. Most streaming sites have recommendations (Twitch, Youtube, Facebook Gaming) on what to use. These are ours:

Upload Speed

* Important Note for High Motion Content. If you are going to stream high motion scenes (i.e. Racing games, some Battle Royale games, etc.) we highly recommend reducing your resolution. High motion content cannot be compressed as much, and can suffer from more artifacting (encoding errors) that make your stream look “blocky”. If you reduce the resolution, you reduce the data being encoded, and the resulting viewer quality is higher. For example, for Fortnite, many streamers decide to stream at 1600×900 60 FPS.

Note for New and Upcoming Streamers to Twitch. Transcoding allows a viewer to view your video on a different resolution, thus requiring a lower bandwidth. Twitch only offers guaranteed transcoding to Partners; non-partners may receive transcoding, but it is not guaranteed. This is important if your viewers are on mobile phones or their internet speed is not as fast. You may want to consider streaming at a lower bitrate and resolution to lower the bandwidth required to see your channel.

Recommended Settings

These are our recommended settings for OBS Studio 23. 0 and up. You’ll want to test and adjust these settings by proceeding with a local recording to verify you’re happy with the results.

To access the settings, click on the Settings button on the bottom right.

Video Tab Settings

  • Base (Canvas) Resolution: Set the resolution you normally play at. That is, your desktop resolution (if you play in borderless mode), or the game resolution you normally enter (if you play in full screen).
  • Output (Scaled) Resolution: Enter the resolution appropriate for your Upload Speed and Bitrate, as we discussed in the previous section.
  • Downscale Filter: This allows you to select a downscale filter that will provide a small image sharpness enhancement, at the cost of some encoder workload. NVENC is very efficient and typically runs at low utilization, so we recommend using this with the Lanczos, 36 samples option for the best quality.
  • FPS: Enter the FPS appropriate for your Upload Speed and Bitrate, as we discussed in the previous section.

Output Tab Settings

If you want an easy, out of the box configuration, then do the following:

  • Output Mode: Simple
  • Streaming:
    • Bitrate: Enter the Bitrate appropriate for your Upload Speed, as we discussed in the previous section.
    • Encoder: Select Hardware (NVENC).
    • Enable Advanced Encoder Settings: Unchecked. We collaborated with OBS to fine-tune these settings, so it just works!
    • Encoder Preset: Quality. This is already the default option. Note that it is only visible if you check Encode Advanced Encoder Settings.
  • Recording:
    • Recording Path: This is the directory where the videos will be saved. Make sure the hard drive you select has enough space!
    • Recording Quality: High Quality typically works for most users, but you can change this to Indistinguishable Quality if you have enough disk space or are going to do short videos (about 60 seconds).
    • Recording Format: FLV or MKV.
    • Encoder: Hardware (NVENC).

Other Settings

There are 2 other things you want to configure to ensure a smooth stream:

  • Windows: Make sure you update to Windows 10 version 1903, and enable Game Mode. This version includes performance enhancements for streaming, as well as an updated Game Mode compatible with streaming.
  • GPU Utilization: If your GPU utilization is above 95% Windows will start prioritizing the game over everything; this can, in some cases, make your stream lag. To solve this, OBS added an option in OBS 24. 0.3 to prioritize OBS Studio over the Game. Just run OBS as Admin, and your stream will be silky smooth.

If for some reason you don’t want to run OBS in Admin mode, you can also limit your GPU usage to be below the 95% threshold. To do this, you can:

  • Cap FPS in-game, run the game in Borderless Windowed mode, reduce game graphics or resolution, or turn V-Sync on.
  • Run all assets at 1080p. To do that, double click on the source in OBS and under Resolution select Custom and specify a resolution equal or under 1080p.

And there you have it! We hope this helps you improve your stream quality and reach your goals. Leave us a comment if this worked for you or if you’d like us to update the guide with other info. Happy streaming!

Advanced Settings

If you want to mess around with all settings, here are our in-depth recommendations.

Streaming Settings

  • Output Mode: Advanced. This gives you access to all the settings. Let’s start!
  • Encoder: Select NVIDIA NVENC H.264 (new).
  • Enforce Streaming Service Encoder Settings: Leave this checked, this will ensure that if you enter a wrong value by mistake it gets corrected.
  • Rate Control: Select CBR. This determines the rate at which frames are going to be encoded.
  • Bitrate: Enter the bitrate appropriate for your Upload Speed, as we discussed in the previous section. Keep in mind that some platforms have a maximum bitrate (i.e. for Twitch it’s currently 6000 Kbps.).
  • Keyframe Interval: Set to 2. Streaming platforms may limit what you can select here, and most require a setting of 2.
  • Preset: Select Quality. You can change this to Max Quality to enable 2-pass encoding; this will provide you a minor quality increase but may cause problems in limited situations in maxed out GPUs.
  • Profile: Set to High. Profile determines a group of settings in the H.264 Codec. It doesn’t impact performance and gives access to a set of features that are key to streaming, so this should always be set to High.
  • Look-ahead: Checked. This allows the encoder to dynamically select the number of B-Frames, between 0 and the number of B-Frames you specify. B-frames are great because they increase image quality, but they consume a lot of your available bitrate, so they reduce quality on high motion content. Look-ahead enables the best of both worlds. This feature is CUDA accelerated; toggle this off if your GPU utilization is high to ensure a smooth stream.
  • Psycho Visual Tuning: Checked. This enables the Rate Distortion Optimization in the encoder, which greatly optimizes the way you use bitrate, improving image quality on movement.
  • GPU: 0. If you have 2 GPUs in your system, you can select which one is used to encode. This is not recommended, as NVENC is already very efficient and the little gain you can get from using a second card is lost by having to copy the frame to the second GPU.
  • Max B-Frames: Set to 4. If you uncheck the Look-ahead option, reduce this to 2 B-Frames.

    Recording Settings

    If you want to stream with HEVC, you will also have to adjust your Stream settings. Note that HEVC live streaming is currently only supported by YouTube. To stream to YouTube with HEVC, navigate to the Stream tab and change the Service to YouTube — HLS. You may need to click Show All… to find this option.

    • Type: Standard.
    • Recording Path: This is the directory where the videos will be saved. Make sure the hard drive you select has enough space!
    • Recording Format: FLV; or MKV if you use multiple audio tracks.
    • Audio Track: Leave it at 1 for default; you can add more audio tracks if you are using more sources.
    • Encoder: NVIDIA NVENC H.264 (new).
    • Rate Control: We recommend CQP, although VBR will also produce good results.
      • CQ Level (CQ): 15 (you can decrease the number to get higher quality).
      • Bitrate and Max Bitrate (VBR): 40,000 Bitrate; 60,000 Max bitrate. You can increase these to 100,000 and 200,000 (respectively) for higher quality.
    • Keyframe Interval: 0 or 2.
    • Preset: Select Quality. You can change this to Max-Quality to enable 2-pass encoding; this will provide you a minor quality increase but may cause problems in limited situations in maxed out GPUs.
    • Profile: Set to High.
    • Look-ahead: Checked.
    • Psycho Visual Tuning: Checked.
    • GPU: 0. If you have 2 GPUs in your system, you can select which one is used to encode.
    • Max B-Frames: Set to 4. If you uncheck the Look-ahead option, reduce this to 2 B-Frames.

    Recording and Streaming HDR with Hevc and HDR

    With OBS version 28, you can stream with HEVC to platforms that support it. HEVC is an improved codec that provides 15% better encoding efficiency than H.264 (i.e. it provides quality as if you streamed with 15% more bitrate). HEVC — and OBS version 28 — also allow you to record and stream HDR content.

    HOW TO RECORD AND/OR STREAM WITH HEVC

    If you want to record or stream with HEVC, in OBS navigate to your Output window and change the Encoder to Hardware (NVENC, HEVC) for the Streaming or Recording settings, as needed.

    If you want to stream with HEVC, you will also have to adjust your Stream settings. Note that HEVC live streaming is currently only supported by YouTube. To stream to YouTube with HEVC, navigate to the Stream tab and change the Service to YouTube — HLS. You may need to click Show All… to find this option.

    Now you should be able to connect your YouTube account.

    Finally, navigate to your YouTube Live settings on YouTube.com, and make sure that your Latency setting is set to Low or Normal (do not use Ultra Low as it is not compatible).

    Streaming or Recording in HDR

    HDR — or High Dynamic Range — allows you to increase the range of light of your content. You can record and/or stream with HDR. 

    Note that:

    • HDR content can look washed off in non-HDR displays, so you don’t want to turn this on if your display does not support HDR, or if the platform you are streaming to does not support HDR.
    • HDR requires HEVC; it’s not compatible with H.264.

    In order to enable HDR, we’ll need to make sure that:

    1. You have an HDR monitor.
    2. Your Windows and Game settings have HDR turned on.
    3. We configure your full pipeline in OBS to enable HDR.

    Windows and Game Settings

     

    Start by making sure that you have HDR turned on for your Display in Windows. Right Click on your desktop > Display Settings, and turn on Use HDR.

    Next, open the game you want to record or stream, go to the settings and make sure HDR is turned on. In Windows 11 there’s a feature called Auto HDR that enables a virtual HDR mode for any game. This is also a valid option.

    OBS Settings

    In OBS, start by going to the Advanced tab and changing the Color Format to P010 and the Color Space to Rec. 2100 (PQ).

    Next, we need to adjust the Game Capture source. Double click it (or right click it and go to Properties), scroll down find the RGB10A2 Color Space. Make sure this is set to Rec. 2100 (PQ).

    Your content should now be ready to be captured and/or streamed in HDR! But remember, in order to record and/or stream in HDR you need to change your encoder from H.264 to HEVC. You can visit the How to Record and/or Stream with HEVC section above to adjust this.

    About NVENC

    NVENC is NVIDIA’s encoder. It’s a physical section of our GPUs that is dedicated to encoding only. This means that your GPU can operate normally regardless of whether you use this region to stream or record. Other encoders, such as x264, use your CPU to encode, which takes resources away from other programs such as your game. That’s why using NVENC allows you to play games at a higher framerate and avoid stuttering, giving you and your viewers a better experience.

    In the last two GPU generations we have made great improvements to NVENC, helping deliver best-in-class output quality. NVENC in the GTX 10-series GPUs provides superior quality than x264 Very Fast, the most commonly used x264 preset. And in the new RTX 20 and 30-series, NVENC performs better than x264 Fast and on par with x264 Medium, a preset that requires an expensive dual PC setup.

    One thing that is great about NVENC on the GeForce RTX 20 and 30-series and GeForce GTX 1650 Super and up is that all GPUs have the same NVENC with the same performance and quality, from the RTX 2060 to the RTX 3090. NVENC also benefits from our own NVIDIA Video Codec SDK, an advanced set of tools that help improve the encoded quality and that we constantly update to help you get the best out of your NVIDIA card.

    Finally, if you are using an NVIDIA GPU you have access to GeForce Experience’s Game Filters, which allow you to further improve the image quality of your viewers via software by enhancing color, adding sharpness, or introducing cool effects.

    About NVIDIA Broadcast

    NVIDIA Broadcast transforms your gamer den into a home broadcast studio, upgrading standard webcams and microphones into premium, smart devices through the power of AI. Improve the video and audio quality of your livestream through AI capabilities such as virtual background or webcam auto frame, and microphone noise removal. With dedicated AI processors called Tensor Cores on GeForce RTX GPUs, the AI networks are able to run high-quality effects in real-time.

    NVIDIA Broadcast features include:

    • Noise Removal: use AI to remove background noise from your microphone feed – be it a loud mechanical keyboard or the AC. The AI network can even be used on incoming audio feeds to mute that one friend who won’t turn on push-to-talk.
    • Virtual Background: use AI to remove the background of your webcam feed and replace it with game footage, a replacement image, or even a subtle blur.
    • Auto Frame: use AI to track your head movement, zooming and automatically cropping on your head so you are always in the frame, even as you move around.

    When not broadcasting, these features can also enhance your video conference calls and voice chats, making NVIDIA Broadcast a perfect AI companion for broadcasters and gamers alike.

    NVIDIA Broadcast is compatible with a wide range of broadcasting, video conferencing and voice chat apps. These include OBS Studio, Streamlabs, Xsplit, Discord, Skype, Zoom, Webex, Microsoft Teams, Google Meet and more.

    About the GeForce-optimized New Version of OBS Studio

    We have collaborated with OBS to improve support for NVIDIA GeForce GPUs. The new OBS Studio, version 23.0, will leverage the NVIDIA Video Codec SDK, which will greatly improve performance and reduce the FPS impact of streaming and recording. We have also tweaked some of the background settings of NVENC to improve quality, especially for the RTX 20-Series GPUs.

    How to Debug Problems

    Streaming can be very complicated, but it’s particularly hard to debug. There are many things at play when you stream, so we are going to try to provide you some help on how to identify what is going wrong and how to fix it.

    Components

    Streaming uses the following components:

    • Your PC: This includes hardware and software.
    • Local Internet: WiFi or cabled internet + your Router.
    • Your connection: To your service provider.
    • The platform: Twitch, Youtube, Facebook Gaming, etc.
    • Viewer’s Internet: Typically Wi-Fi, but can also be 3G/4G.
    • Viewer’s device: keep in mind 35% of Twitch viewers are on mobile.

    If something is failing, we want to first identify what component may be failing, so we don’t go crazy trying to fix something that was never broken in the first place. Typically, this means that the first test you should do is a Speed Test to make sure that you don’t have internet problems in your local internet or your connection. Second, make sure the platform hasn’t issued an alert that they are down or are experiencing problems. Then based on what error you get, you start looking at one thing or another in your PC.

    How to check what’s happening to the encode

    OBS Studio includes a very useful tool: the Stats Window. To bring it up, click on View > Stats. This window will show you Lagged and Skipped frames, Dropped frames, and Encode FPS.

    This window will show you:

    • FPS at which you are encoding.
    • Latency to encode each frame.
    • Missed Frames — problems with GPU.
    • Skipped Frames — problems with CPU.
    • Dropped Frames — problems with network.

    Common Error Types

    Stream is missing FPS. The stats window will show missed frames. While streaming and missing frames, pull up the Task Manager > Performance, Click on GPU and check the 3D load and Encoder load.

    Solutions:

    • If the 3D load is above 95%, especially at 1440p or 4K setups, Windows may be prioritizing the Game over OBS. To fix this, we have a special mode inserted on OBS 24.0.3 where you can prioritize OBS above the Game. Just run OBS in Game Mode.
    • If the Video Encode load is maxed out, we need to lower the load. NVENC can do up to 8K30, so the only way to overload it is to do 2x4K60 streams. If you are encoding 4K60, make sure that your quality setting in OBS is set to Quality, not Max Quality. Max Quality does 2 pass encoding (i.e. encodes twice), which is too much for the encoder.

    Image looks very washed out. The most likely issue is trying to push too much quality with not enough bitrate. Consider reducing the resolution, and frame rate (if needed), and try again. If quality improves, then adjust until you find your sweet spot.

    MSI Afterburner can overclock NVIDIA workstation graphics cards

    3DNews Technologies and IT market. Graphics card news MSI Afterburner has learned how to overclock…

    The most interesting in the reviews


    07/29/2021 [17:12],

    Nikolai Khizhnyak

    Edition Igor’sLAB found that MSI Afterburner 4.6.3. Beta 3 for tuning and overclocking video cards supports manual overclocking of graphics accelerators intended for use as part of workstations. Although before that there were several ways to change some characteristics of NVIDIA and AMD graphics cards for workstations, full-fledged overclocking was not available for them. nine0007

    Image source: Igor’sLAB

    It should be noted that NVIDIA itself does not want such solutions to be overclocked for a number of reasons. Due to these manipulations, stability, temperature indicators of the graphics accelerator may suffer, as well as increase the noise level and problems with ECC RAM.

    NVIDIA RTX A5000 Overclocking

    Igor’sLAB Editor Igor Wallosek noticed that MSI Afterburner’s latest beta version for fine-tuning graphics card performance offers support for Ampere RTX models for workstations. Version 4.6.3 Beta 3 of the program allows you to adjust the frequency of the GPU, memory, as well as change the power consumption settings and the operation of the cooling fans. True, the latter feature is only available for Turing-based NVIDIA RTX series graphics cards. The program itself received a number of updates, including support for new APIs. It redesigned the feature of setting the operation of the fans and the OC Scanner extension, which determines the potential for additional overclocking of the video card. It is very likely that some of these changes ended up accidentally unlocking the overclocking feature of specialized graphics cards, which are usually only available on gaming graphics accelerators. nine0007

    For the tests, Igor’sLAB used an NVIDIA RTX A5000 graphics card based on a GA102 GPU with 8192 CUDA cores and equipped with 24 GB of GDDR6 EEC video memory. The declared maximum frequency of the graphics processor of this video card is 1440 MHz. Igor Vallosek managed to increase this value to 1590 MHz.

    However, in real tests, this brought a very small increase in performance — about 5%.

    The ability to overclock such video cards is unlikely to gain popularity among their owners. Ultimately, the price of these video cards is much higher than gaming ones, and their use in such modes that go beyond the official specifications can easily void the owner’s warranty. Also, do not forget that such video cards are usually equipped with cooling systems with a single tangential fan, which are clearly not suitable for experiments with manual overclocking. nine0007

    3. How to set up MSI Afterburner monitoring in games: find out the temperature and load of the CPU and video card
    4. Video card load in games: how to check why the load is not 100%, what is disclosure

    Buy and installing a video card is only half the battle. It still needs to be set up properly. In this article, we will explain what to do and give recommendations on how to configure the NVIDIA Control Panel. nine0007

    Installing the driver

    The very first thing to do after installing a new video card is to download and install the drivers. If before that you had another video card, then it is advisable to remove the old driver. The easiest way is to use the Display Driver Uninstaller utility.

    You can download the NVIDIA driver from the official website. Fill in the fields according to your video card and operating system. Also choose Game Ready, as studio drivers are designed for production software. nine0007

    Dynamic range and color format

    After installing the driver, you need to go to the NVIDIA Control Panel. You can get there by clicking on the NVIDIA tray icon or right-click on the desktop and select the desired item from the menu that appears.

    On the left under Display, select Change Resolution. The resolution and refresh rate should be optimal by default, but if this is not the case, then you need to fix it manually. Set the native resolution of the monitor and the maximum available refresh rate. In our case, this is [email protected]Hz. nine0007

    But the item «Apply the following settings» is already more interesting. For the best picture, you need to set the RGB color format and full dynamic range. In the case of a DisplayPort connection, this should be the default, and if HDMI is used, then the range may be limited. In this case, the picture may appear pale, faded.

    YCbCr 422 and 444 color formats should not be used on the monitor. But they can be set if RGB is not available, for example, due to the old version of HDMI, which lacks bandwidth. So, a 4K @ 60Hz signal with HDR via HDMI version 2.0 cannot be transferred to RGB with a full range. There is nothing terrible here, the main thing is to set a limited range in the TV / monitor settings. nine0007

    Also go to the «Video» section and «Adjust video color settings». Turn on the «With NVIDIA settings» switch and go to the «Advanced» tab. Activate full dynamic range.

    Manage 3D settings

    By default, all graphic settings are set by the 3D application (in our case, the game). That is, you change graphic settings, such as the quality of anti-aliasing and anisotropic filtering, directly in the game. But the NVIDIA driver also allows you to fine-tune the graphics settings. So, for example, you can set anti-aliasing for older games where there is no such option at all. nine0007

    Please note that there are two tabs:

    • global settings — settings apply to each game,
    • program settings — only for the selected application.

    Work better with a specific application to find the optimal settings. If the game you need is not in the drop-down list, then just add its executable file (with the .exe extension). Let’s analyze the parameters in more detail.

    • Sharpen the image. nine0142 Useful if the picture is too soapy and you need to slightly increase the clarity of the game. It is not worth bending with intensity, as the picture will be distorted. It’s best to leave the default values ​​and don’t forget to check the «Scale with GPU» checkbox.
    • CUDA GPUs. Leave as default or select your primary graphics card.
    • DSR smoothness and DSR degree. Allows you to render an image at a higher resolution, but display it at a resolution supported by the monitor. Creates a very high load on the video card. If you have a powerful enough computer to play at 1440p or even 4K but have a 1080p monitor, you can give it a try. You can also disable this mode for older games. The DSR-smoothness slider affects the sharpness of the image. nine0101
    • Anisotropic filtering. Affects the clarity of textures. This setting is available in almost all games, so you can not touch it, but set it directly in the application. It has little effect on performance, but on weak machines it’s still better not to get carried away.
    • Vertical sync. This is vertical sync or V-Sync. Prevents tearing (frame tearing) and prevents FPS from rising above the monitor’s refresh rate. If your monitor or TV supports G-Sync, Free Sync and VRR, then your picture should be smooth anyway. In other cases, V-Sync will help. By default, it is better to turn it off, but if tearing is significant and interferes, then activate one of the modes. This may result in a slight decrease in performance. nine0101
    • OpenGL rendering GPU. Select your primary graphics card.
    • Ambient lighting shading. Responsible for realistic reflection of light and shadows. Does not work on DX 12 and is not supported by all games. If there are performance issues, it’s best to disable it.
    • Shader caching. Stores compiled shaders so they can be reused later. Enabled by default, leave it as it is. nine0101
    • Max. frame frequency. You can set a limit on the frame rate. Many games are able to limit FPS on their own, but if there is no such parameter or you are too lazy to set it up every time, then you can do it through the NVIDIA panel. It is recommended to set a limit equal to the refresh rate of your monitor.
    • Max. the frame rate of the background application. Reduces FPS for minimized game. That is, if you leave the game running in the background, it will not heavily load the hardware. nine0101
    • Multi-frame anti-aliasing (MFAA). Can put a lot of stress on the graphics card, so it’s best to leave it off. It makes sense to enable anti-aliasing for older games that are no longer difficult for the video card. The picture can become much nicer.
    • Thread optimization. It doesn’t make much sense, so it’s better to leave it on autoselect by default. If the game does not support multithreading, then this setting will still not help.
    • Preferred refresh rate. The parameter should be touched only if the game settings do not allow you to set the desired frame rate. Again, if the game does not support, for example, 144 Hz, then this setting alone will not solve the problem.
    • Low latency mode. Doesn’t work in DX 12 and Vulkan. If the controls don’t seem to be responsive enough, try activating the feature, but performance may even suffer.
    • Power management mode. Set to adaptive or maximum performance mode.
    • FXAA antialiasing. This is also a type of smoothing, but it is less demanding on resources. It can also make the picture more soapy, which not everyone likes. We recommend leaving the default.
    • The following parameters are: Antialiasing — Gamma Correction, Antialiasing — Options, Antialiasing — Transparency, Antialiasing — Mode. We recommend leaving them by default and using the anti-aliasing settings in the game itself. But you can try to enable these items for older games where this option is not provided. nine0101
    • Triple buffered. Only needed if you are using V-Sync.
    • Texture filtering — anisotropic optimization. Enable for weak computers.
    • Texture filtering — quality. For weak computers, set «Performance». In other cases, it is better to leave the default.
    • Texture filtering — negative UD deviation. Leave the default.
    • Texture filtering — trilinear optimization. Leave the default.

    After selecting the settings, do not forget to apply them by clicking on the appropriate button at the bottom of the screen.

    GeForce Experience settings

    There is also something worth doing in the GeForce Experience program that comes with the driver. First you will need to create an account, then you can use all the features.

    Here we recommend enabling the in-game overlay. With it, you can take screenshots and record gameplay. Please note that Instant Replay records video in the background and therefore affects performance. nine0007

    Overclocking in MSI Afterburner

    There is nothing wrong with overclocking if you do not climb into the jungle. You need to install the MSI Afterburner utility and move a couple of sliders. At the same time, nothing will burn or deteriorate, and you will receive a guaranteed increase in frames.

    1. Increase Power Limit to maximum value. You can’t put in too much anyway.
    2. Add 50-100 MHz to the core clock and test with FurMark. Doesn’t crash, doesn’t artefact? Temperatures above 80 degrees are best avoided. If the card gets very hot, reduce the frequencies or increase the speed of rotation of the coolers. nine0101
    3. Next, take the memory frequency. Raise 100 MHz at a time. And test again. As you can see, in our case +500 and everything works stably.
    4. Don’t forget to apply the settings.
