Absolute highest form of SSAA?

Lavans

Looking through Nvidia Inspector's list of AA settings, I'm curious to know which of the super sample methods is technically the highest?

I'm inclined to believe that SVCAA 64x is the highest, but I can't find any info on that setting.

8x SGSAA imo the performance hit everything takes all that isnt worth it, it look nice though.

there is now 64x AA anything on any gpu card and if it is listed in it, then it is hidden in inspector for reason and now shown in nvidia cp much like SGSAA is hidden.

If 8x SGSAA has huge hit to performance I can only image what 64x would be

CHALLENGE ACCEPTED.

...maybe.

I'm curious about 64XSVCAA now.

I had some success with MIXEDSAMPLE_6X in the past.

Depending on the game SGSSAA, with transparency turned off.

I just did some comparisons in Guild Wars using different methods of SSAA. The modes I tested were 64xSVCAA (8v8), 64xSVCAA (8v8) + 8xSGSSAA, 64xSVCAA (4v12), 64xSVCAA (4v12) + 8xSGSSAA, 4x4AA, 4x4AA + 8xSGSSAA, 32SAA, 32SAA + 8xSGSSAA, and finally 8xSGSSAA.

I couldn't tell much difference between the above modes TBH. The biggest performance hit by far was 64xSVCAA (8v8) + 8xSGSSAA.

What are some good games to test AA with? I would try Mass Effect 2 because of all the shader based texture aliasing, but I get a much harder performance hit when using SSAA on my GTX680 in UE3 based games than I ever did on my HD5970, so I'm not sure if the drivers are working properly.

Did some comparisons using L4D2. This is running off a GTX460M (since I'm not at home). All screen shots are at -3.0 LoD.

64xSVCAA (4v12)

64xSVCAA (4v12) + 8xSSAA

64xSVCAA + 8xSGSSAA

32xS

32xS + 8xSSAA

Have a read of this mate;

Btw I was wrong about SGSSA - it's not the best quality. I always used it in BF2 though as I liked the way it looked compared to regular SSAA.

Thanks for the article. Unfortunately it doesn't quite describe what SVCAA is and how it compares to other modes of SSAA. It seems to have a similar visual quality to combined SSAA mode ( 2x2 + 2x, 4x, 8x MSAA ).

I meant to give you this link instead, explains different types much better but still doesn't mention SVCAA sorry (it's a little outdated - from 20089).

Worth a read though.

Combine 32xS and 8x sparse grid modes. It won't be a playable setting though.

Most definitely not. Ordered grid SSAA is pretty much the worst SSAA method.

That explain greatly the difference in image sampling quality,this image should be used for IQ comparison all the way.
But 64 subpixels are enormous for any game currently except maybe some oldie-goodie.

svcaa is csaa with 64 or 128 coverege samples..

Actually, 64xSVCAA 4v12 doesn't hit a whole lot harder than 32xS and seems to have a better rendering IQ for distant objects. A higher end card should be able to run a lot of games with it at 1080 with little issue, save for games that are graphically demanding of course. SLI users should have no issue with it.

Source? I find it odd that SVCAA is "just" CSAA considering the difference in IQ and performance hit.
