Aah, a CC error from a previous review. I'll update thanks, of course MFAA was done with 2xMSAA+MFAA and is compared with 4xMSAA.

Thanks for the article Hilbert 🙂

Thnx, it works without 2xMSAA in Cod AW. I hope it works with Far Cry 4

Can't wait to test it!

Sounds like a more developed Version of the old Quincunx Anti-Aliasing, waiting for Driver to test it

Now to see on how many games/engines it can be made to actually work :P

So how does this compare to TXAA? TXAA also uses the data from previous frames to provide anti-aliasing, how does MFAA differ from that? Edit: So wait, this is basically boosting the performance of MSAA? Cool.

Hilbert, given the nature of how MFAA works, did you notice any artifacts when running Crysis 3 @ QHD? I would imagine in low frame rate scenarios that the temporal reprojection would spit out some nasty looking stuff. Kinda curious to know how well of a job nvidia did on blending the two frames together.

Anyone remember Temporal AA that ATi had back in the day, or SMAA T2x of recent? That's all this basically is, a mix of these. EDIT: Even that whole bit about programmable AA being a foundation of something reads a lot like the ATi article from here, ages ago. EDIT2:

ATI revealed Temporal Anti-Aliasing, a new anti-aliasing technology their chips were capable of. By taking advantage of the frame-to-eye effects of a framerate higher than 60 frame/s, the GPU is able to better smooth aliased edges by rotating the anti-aliasing sampling pattern between frames. A 2X software setting became perceptively equivalent to 4X.

https://en.wikipedia.org/wiki/ATi_Radeon_R400_Series EDIT3: This also explains why the screenshots on the review look like MSAA 2x: because technically, they ARE @ MSAA 2x. Every frame renders with MSAA 2x, but with alternating patterns between frames. Impossible to capture in standard screenshots.

No at low framerates the temporal filter will disable itself steering away shimmering and flickering etc.

I can see the substantially lower MFAA quality on the comparison screens quite easily. And the FPS hit isn't that crippling either on the two top of the line cads. So for now MFAA seems quite useless. Once the 9x0 cards get dated, or older cards will get access to the mode, it will start to shine.

so basically this is the same as AMD's 2EQ AA + MLaa
