Web launched!
We present a new image-based, post-processing antialiasing technique, which offers practical solutions to the common, open problems of existing filter-based real-time antialiasing algorithms. Some of the new features include local contrast analysis for more reliable edge detection, and a simple and effective way to handle sharp geometric features and diagonal lines. This, along with our accelerated and accurate pattern classification allows for a better reconstruction of silhouettes.
Our method shows for the first time how to combine morphological antialiasing (MLAA) with additional multi/supersampling strategies (MSAA, SSAA) for accurate subpixel features, and how to couple it with temporal reprojection; always preserving the sharpness of the image. All these solutions combine synergies making for a very robust technique, yielding results of better overall quality than previous approaches while more closely converging to MSAA/SSAA references but maintaining extremely fast execution times. Additionally, we propose different presets to better fit the available resources or particular needs of each scenario.
IMPORTANT: designed to viewed in HD at full screen. As compression hides aliasing, we encourage to download the HD movie in Downloads to better see the differences between the different techniques.

How do I have SMAA and FXAA injector mod at the same time? : V
How do I have SMAA and FXAA injector mod at the same time?
» Mon May 28, 2012 12:00 am
SMAA is pretty good.
It provides decent antialiasing and has very low performance hit (for me). I therefore prefer it more than MSAA.
However, SMAA (http://mrhaandi.blogspot.com/p/injectsmaa.html) comes with a d3d9.dll file.
The FXAA injector mod also comes with a d3d9.dll file.
Thus they conflict with each other.
I’ve read before that there is a way to have SMAA and Enhanced Shaders on at the same time, if you alter the proxy in the end.ini… but FXAA injector doesn’t got anything like that.
I therefore wonder, is there any way to have SMAA and FXAA injector mod at the same time?

Maybe you can have both by using the ENBSeries Patch.
You only have to rename the d3d9.dll’s and then edit it properly into the enbpatch.ini
But I don’t know if it works with 2 alternate d3d9.dll’s

You cannot as far as I know, so just use injector and 2xMSAA if 4x is too much.

I prefer not to use the ENB patch (even if that would work to also have FXAA and SMAA at the same time), because I got none of the graphical problems that it intends to fix, and it just lowers my FPS, thus making SMAA pretty useless since then it would no longer be cheap in terms of performance.
You cannot as far as I know, so just use injector and 2xMSAA if 4x is too much.
That’s what I feared. Just went here and see if someone knew a workaround.
I guess I’ll use just FXAA then. MSAA, even if 2x, just gives me a big mouse lag and less FPS.
———————————
Also, just wondering: is transparency multisampling is broken in Skyrim right? The .ini setting has no effect, and as far as I know it can’t be forced through driver settings either (cause bugs).

Multisample is buggy with Skyrim, so use supersample if you have the hardware to. Multisample makes NPC’s go transparent.

I tried supersample, but 2x of it dropped my FPS by 15.
Not worth it imo…
Didn’t FO3 have transparency multisampling that worked? Did anyone remember how big the FPS hit was for that?

It’s probably just the game. I can play Crysis with supersampling on and it gets nowhere near as laggy as Skyrim. Honestly, the game has so many tech issues it’s like a minefield.

Nope, tried to do this myself with ENB, 4GB Skyrim Launcher, etc. and couldn’t get it to work. Since the SMAA Injector is based on the FXAA Injector they seem to internally conflict with each other, probably overwriting each other’s functions.
I suggest using Skyrim Enhanced Shaders (or straight-up ENB Series) with SMAA Injector as the ENB Series / Enhanced Shaders can give you all the same shader effects, including new ones.
Also take a look at this post I made comparing regular AA (MSAA), FXAA, and MSAA with the addition of various Nvidia-specific tweaks: http://www.gamesas.com/topic/1320263-2560×1600-high-res-comparison-of-different-aa-hd-mods-and-nvidia-tweaks/
Also has pictures with Skyrim Enhanced Shaders. Use the PNG or Bitmap version for the best quality.

Problem is, Enhanced Shaders / ENB series gives such a big performance hit compared to FXAA. Maybe if they fix the performance hit in the future I’ll use it.
What also would be great if there was an SMAA injector mod.

Actually with Skyrim Enhanced Shaders it uses a different version of ENB Series that allows you to set the VendorID and DeviceID in enbpatch.ini, which takes the FPS hit down to around 2% (1 or 2) at most. The main page on Skyrim Nexus explains this.
It’s the very latest ENB Series (which SES has under Optionals) that lacks enbpatch.ini and the VendorID and DeviceID options.

Experts consider increased sensitivity to fuel quality to be one of the main disadvantages of injection systems. If it differs even slightly from the standards recommended by the manufacturer, then the finely tuned multiport fuel injection system begins to malfunction. Over time, these blockages can lead to the fact that individual cylinders are turned off, or a lean mixture gets inside. This leads to increased detonation and gradual destruction of the working surfaces of the engine, displacement of the axes and directions of travel, etc. Injector cleaning can be carried out without dismantling the power plant.
To use them, simply pour a certain amount into the fuel tank and continue to operate the car. The action is reduced to the gradual dissolution of blockages. Rapid removal is possible, but then large fragments of deposits can break off, which is fraught with bad consequences. Therefore, a phased elimination is better with the further release of dissolved deposits into the exhaust pipe along with the products of combustion of the fuel.
The second phase of the impact is to provide long-term protection. The surfaces of the metal parts of the engine are saturated with special substances, which prevents further deposits from forming. After the first cleaning, additives can be used prophylactically to prevent the appearance of new formations.
