NVIDIA's New AA Algo is TXAA, Adaptive V-Sync and New 3DVision Surround Detailed

With Kepler architecture, NVIDIA has three new star technologies that will help it with this round: TXAA, a new anti-aliasing algorithm that offers image quality comparable to 16X MSAA, with the performance-penalty of 2X MSAA (if not less); Adaptive V-Sync which is sure to win gamers by the millions; and a redesigned display logic that supports up to four displays from a single GPU.

TXAA, which we talked about a little earlier, turns out to be a super-efficient temporal anti-aliasing algorithm. It has two levels: TXAA(1), and TXAA2. TXAA1 provides the image quality comparable to 16X MSAA, with the performance-penalty of 2X MSAA; while TXAA2 offers image quality higher than 16X MSAA (unlike anything you've seen), with the performance-penalty of 4X MSAA. Since few games natively support it, you will be able to enable it through the NVIDIA Control Panel, in the application profiles, provided you have a Kepler architecture GPU.

More pictures follow.

Adaptive V-Sync is a smart frame-rate limiter that fluidly adjusts frame-rate when heavy 3D scenes drop frame-rate below monitor refresh-rate and above it. When frame-rate is lower than monitor refresh-rate, lag occurs, and overclocking attempts to overcome it. When frame-rate is higher than monitor refresh-rate, page-tearing occurs, and the normal functionality of V-Sync takes over. Adaptive V-Sync makes these transitions "organic".

Then there's the new 3D Vision Surround, bolstered by a redesigned display logic, which addresses the two-display limitation of NVIDIA GPUs. You can now connect as many as four monitors to a GeForce Kepler GPU, enabling 3-monitor HD 3D Vision Surround setups. You no longer need more than one GeForce GPU to connect more than two monitors. The new 3D Vision Surround is said to work in conjunction with Adaptive V-Sync to ensure the center display has higher frame-rate (since it's at the focus of your central vision), at the expense of the frame-rates of the two side displays (since they're mostly at your peripheral vision). This ensures there's a balanced, high-performance experience with multi-monitor gaming setups.

Not really. I never used ingame FSAA settings. I always set it through drivers and there you can pick whatever setting you want.

Yes, but if it's forced in driver control panels, the chance is greater that it's using the fancy new AA method might be part of the reason for the high scores. I'm sure I mentioned this before...;)

Well, why wouldn't you want to benefit and use the new algorithm instead of crappy one bundled with the game?

Kepler looks like a real winner.

is this like unlimited detail technology...

No. But it may provide unlimited anti-aliasing if the conditions are right (contrast difference). At least with MLAA you could sometimes (very often actually) so smooth edges you could easily compare it with 64x FSAA or even more.

thematrix606You wish the 7970 did so well, it does not.
You are right, those extra few FPS above what you monitor can draw make a real difference.

Pushing a few extra pixels, and the china site doesn't offer any other specs but has a similar increase in the the 580 scores.

I am led to believe the margin of difference in 5-7% depending on application at the best, but we have yet to see actual overclocking numbers for final enthusiast numbers.
