    Anyone noticed any difference with GM2xx GPUs?
    Still AA fix needed?

    I'd assume still needed. But you never know

    Well the game has no AA on the PC, unless you set the resolution higher than that of your screen and 'downsample' it. That is not very effective though and not only reduces your framerate but also uses a lot more VRAM, which could be the difference between the game running smoothly or with stutters.

    The game also use DirectX 11 so you cannot force AA using a compatibility flag unfortunately.

    You can either force driver FXAA through the NVIDIA game profile or use a FXAA or SMAA injector such as SweetFX. SMAA would give better quality AA with less blurring IMO. Remember the game is 64-bit though so you'll have to use the 64-bit SweetFX files.

    SMAA is not very efficient in mordor, unfortunately.

    It is as efficient as a post processing AA can be, I definitely see an improvement.
    It's mostly because the game is very sharp and crisp so SMAA may seem less effective, but in reality it's just that you're used to games with a ton of blurry post processing.
    I for once am very happy Mordor doesn't have a bilion of awful filters and color grading.

    For me, no amount of quality in other areas can make up for the immersion breaking jaggies.:(

    Unfortunately for me, the SweetFX injector needed for Shadow of Mordor doesn't work with Windows 8.1. If anybody knows of an alternative 64 bit DX11 SMAA injector that works on Windows 8.1, please share haha. I'm using FXAA atm, and while it works pretty well in this game, I'd definitely prefer SMAA.

    I use Radeon Pro for SMAA and SweetFX, I followed this guide to set it up.

    Oh yeah, I forgot about that. I have in fact made a guide for setting up RadeonPro for sweetfx and SMAA myself....kinda odd that I forgot...

    Edit: So this might be the only time I've ever felt this way, but I actually like FXAA in SoM more than SMAA. SMAA doesn't hit anything that isn't an edge well, and SoM has a **** ton of jaggies that aren't on edges. Also, I think Nvidia may have improved their FXAA algorithm a bit. It seems to reduce shimmering more than it used to.

    It's just a matter of the fact that FXAA can handle and average high frequency information on the entire frame. That SMAA can't. However SMAA can handle geometry aliasing slightly better in some cases where diagonals are concerned.
    Once downsampling is introduced any blurring is basically irrelevant.

    Both are still just post-AA however and won't reduce any temporal aliasing without being combined with super sampling.

    It does look like they used some kind of AA on PS4 though maybe from a shot released. So the lack of even a remotely decent Post-AA option would've been nice other than just a "Hey, you can brute force OGSSAA with this quick and lazy option we set up here"

    Straight up OGSSAA without anything else combined is just as lazy as SMAA or FXAA. Except it costs a lot more performance

    Edge quality alone with 2x2 by itself is pretty poor 9/10 times. And that's if the built in OGSSAA resolution option also works on low resolution fractional based effects. If it bypasses them and just does the main framebuffer, that's going to look even worse.

    I'll use a game where SMAA fares better than FXAA as an example.

    (Both downsampling shots are done with a bicubic filter to represent the best you could get with GeDoSaTo for example)

    Why Lord of the Rings War in the North flag is not on list?

    I see that you posted it in the old AA thread, as it wasn't listed on the old AA list though or on the 3DCenter list am not surprised Cyber missed it.

    Flag for The Walking Dead isn't working for me. I tried 0x204002C1 and 0x200002C1. Any others that might work? I'll continue searching for another.

    Better use 4k with gedosato, previous sgssaa flags was blurry.

    Blurry? I have to disagree based on my own experience with the game.

    However, given the artistic and rendering style of the game. GeDoSaTo should produce good results.

    AA bit: 0x004010C5 4xSGSSAA ONLY.

    AA fix: On

    AA fix comparison:
    Off: http://abload.de/img/pso2withoutaafixfluhr.png
    On: http://abload.de/img/pso2withaafixazu1p.png

    Basically, the contrast is improved a bit and it may or may not make the AA more accurate. I honestly can't tell if that is because of the slight contrast difference or not.

    The bit also works with MSAA, although MSAA isn't recommended with this game. It leaves much to be desired. Most rigs should be able to handle 4xSGSSAA in this game. With High Quality HBAO+ and 4xSGSSAA, my GTX 780 sits at an average of 60% usage at 60 fps.

    The screenshots are 4xSGSSAA shots:1 | 2

    Without AA:1 | 2
