NVidia Anti-Aliasing Guide (updated)

A heads up to everyone, but it seems this workaround for fixing textures in SGSSAA in OpenGL games no longer works with the latest drivers. When it's set to the necessary setting, all the graphics are glitched out instead. Had to go back to 8xMSAA in my OGL games.

 

Well crap that's gonna suck when new cards come out.

i'm on 388.59 and it doesn't happen in Doom 3 for me, anyone ever seen it happen there?

 

Does anyone know Sparse Grid compatibility bits for Cry of Fear?

 

Is it DX9?

 

OGL

 

You can just try forcing using MSAA+TrSSAA Option. If it works, then you are good. If not then you are SOL unless the game has built in MSAA you can enhance.

 

None of the border shaders are compatible, at least in my case, with NVidia Inspector. If I use any of them then anti-aliasing set via NVCP will not be applied in-game.

 

Are you using ReShade? You have to set the depth bit in the anti aliasing flag (0x00400000) for newer versions of Reshade.
The old version 1/2 I don't think needed it. And the old SweetFX injectors do not need it at all.(If you just want a border shader for dx9/11 games, find an old SweetFX download pre reshade days)

 

OK, so I just followed the nVidia forums link that I quoted in this post, and apparently there's a new way to work around the blurred textures w/SGSSAA in OGL issues - enable the FXAA option in Inspector. Just tested this in Anachronox, Hexen II (with UQE H2 source port) and Jedi Academy to make sure it was working. Yes, for once applying FXAA actually makes textures less blurry.

 

@NeoChaos: This actually works in old OGL games with 398.x drivers, thats great. But FXAA on top of TrAA is just weird - I don't like how FXAA affects 2D overlays and texts. I hope there will be another hidden driver parameter to sort this out without FXAA...

Edit: Well scratch that. Just tested in OGL Doom 3 with 398.11 and FXAA on top of TrAA just deactivates TrAA completelly so all the specular aliasing is back. So much for "repairing" the blur. Don't know what others see, but for me it just doesn't work.

 

What's funny is that I dont' get any of the blur people talk about with Doom 3. Maybe it's because of mods, because for example with the Redux mod, post processing effects from sikkmod like Bloom,SSIL DOF and HDR do make the image softer if enabled.
The DoF for example breaks with 8xSGSSAA and causes the DoF to have aliasing, where as 4xSGSSAA does not. But when DoF is activated the in focus areas get AA'd slightly different than without.(Slightly softer but better resolve of some specular problems).

But with it tweaked right, I don't really see any evidence of significant over softening of the image with AA.

Example comparison of some PP effects being enabled with 4xSGSSAA creating obvious blur

Comparison of tweaked settings (Just DoF on Zoom and in Cutscenes along with HDR enabled) without AA and with 4xSGSSAA. There isn't any significant blurring. Text displays are obviously aliased without AA but do get some minor high frequency attenuation with AA on and no LOD adjustments. Same with other surfaces but nothing like the above comparison.

Maybe i'll have to check Vanilla D3 again.

Hard to match the shots quickly but here's Vanilla vs the mod
Very slight sharpness difference (Probably due to having HDR or DoF on in the mod)

What are you guys seeing with AA and Doom 3?

 

@MrBonk: I know how to set it up, no postprocessing here. In vanilla Doom 3 It's not about blur overall - instead some textures are now distorted when using SuperSampling. Mainly some transparent grates under/before lights, and some light bulbs on panels when viewing from angles - it looks like doubled or something (see bellow). In older games like RTCW, Q3A etc. the whole ground texture becomes distorted like that. That hidden flag OGL_OCGCONTROL_DIRECT_NVIR = 2 used to eliminate it completelly, but they must broke it in last few drivers, because all 2D overlays are unreadable noisy mess with it set. Doom 3 is playable, but you know - when seen once, it cannot be unseen. Btw it's not distorted in BFG edition (new engine), but that version really sucks in everything except native WS.

Two sets of screenshots here:

Is there a way to force AA in Crash Bandicoot: N. Sanity Trilogy? Because my friend told she is using SGSSAA and MFAA by simply using "Enhance application setting".

 

That's weird, I don't get this artifact at all with 388.59 with Vanilla doom 3. I don't have that flag set either.
I am on Windows 7 though, don't know if that would change anything.

As far as I know the game is DX11 and uses TAA. So it should be impossible. However, there used to be a glitch in a really old driver that would enable MFAA and create some effect in games that did not have MSAA. I don't think it does that anymore.
So unless they have near lossless A/B screenshots to back it up. I would take it with a grain of salt. Unless you want to try it yourself that is.

TAA+downsampling (Maybe a little sharpening if you find it too soft still.) might be a worthwhile alternative. Depending on how many artifacts the TAA introduces in this game that is.

 

I am on Win7 too, maybe it's GTX1080 specific. I know it was fixable in 388.x and older drivers by that flag, but in 398.x not anymore. I tried D3 vanilla and various source ports, all the same. Will use MSAA only in older id games, it looks mostly OK.

 

I have a GTX 1070, so it's not 1080-specific. Still, sad to see nVidia breaking such a fantastic feature like this - think I'll have to settle for MSAA+FXAA in OGL games for the time being.

 

CB is using FXAA.

 

Any way to get sgssaa in forza horizon 3?

 

Have any screenshots showing on and off?
I was under the impression the console versions used TAA. I haven't played it or seen any lossless comparisons to verify it though.
Either way, if true then yeah downsampling is your only option.

Unless it has MSAA you can use to enhance with SGSSAA. Which will be very costly and may not look great.

 

how to make work 64xS in Medal of Honor Allied Assault (OPENGL) ? I've Tried Change Antialiasing 0x0000002C AA_MODE_METHOD_MIXEDSAMPLE_64X but doesn't worked

EDIT : oh sorry i forgot to apply Antialiasing mode - override any application setting . My BAD !
