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.

What's going to be left once the NDA is lifted? Dribble dribble...

Adaptive V-Sync makes these transitions "organic".
So is this the actual name for the "dynamic profiles".

I'm thinking that V-Sync in conjuction with this TXAA1 is what we're provided in the graph of game title Nvidia present showing it above the 7970 (with regular 8xAA @ 1920x) so interesting! While the word "organic" mean different things for different people... while it can't necessarily be deduce a good or bad, it’s a eccentric use of the word for such an explanation?

I donno how old are you but the average cognitive age that babies are able to use keyboard and mouse is about 20 months so at least i can guess you're that age :)


Hm, no one mentions anything about MLAA 2.0 availability. Where do you select MLAA 2.0 and most importantly, will we, the HD6950 users also get it? Will it be available in Catalyst 12.3 or something?
Are you sure? first of all it will be available at 12.3 beta and 12.4 WHQL, secondly - it will have support for HD4000 series and upwards.

Thx Dj-ElectriC!

@Gublo
Yeah, that confuses me as well. Is the so called TXAA actually FXAA or something? Considering "F" and "T" leters are together on keyboard, it could be a typo spread all over teh web by copy&paste of news...

dude I was just thinking that lol. FINALLY!

And now for anyone that wants to run multiple monitors. You now only need 1 kepler card to do so.

So, these new tricks are not just software but built into the Kepler architecture. CD at S/A made some hoo-haa a while back saying NV had put an Ageia Physx processor on theh Kepler gpu. Maybe he was utterly wrong and it was these pieces of hardware/software thingies???

That is because the pics in the news post are wrong. :D

no it has the physics engine too im pretty sure. But these new features are ran on the GPU, but I dopn't think theres a little specific part in the the chip that does it.

I bet that's another NVIDIA SeriousGamer(tm). NV has a habit of making "serious gamers" (30-something mankids) pose with their hardware, and on their marketing materials.

Can you enable FXAA in Nvidia Control Panel? No. I think now you don't need to put FXAA files into games directory. :rolleyes:

I'd like to see TXAA used with a better picture. I can't tell how much it decreases picture quality or blurs things out. Nivida does do a great job with FXAA.

That's the key right there. "Image Quality of Xx MSAA" is simply too open-ended of a statement. But I don't expect much better from marketing materials.

Like most of these enhancements, I doubt I will see any real world difference.

And most likely not enough to justify the performance hit.

But my eyes aren't what they used to be. :(

Sounds promising.

TXAA1 provides the image quality comparable to 16X MSAA
Are we not supposed to be comparing a x16 with TXAA1 and not 8 ?..

Yeah there is a thought
