Sure? AFR works here really slow with my 2x6800GT@SLI. Not really Sli Support here.

Motion Blur & Lighteffects Off

Here the Screens:
1600x1200 4xFSAA Applicationcontrolled. HighQuality in the CPANEL

and here with SFR enabled: Corruption is not to seen in the Game!

I have tested all the Drivers no Chance.

Not buying it. I see a substantial improvement with AFR turning off Motion Blur/Light Trails. I have seen AFR drop performance. But disabling Motion Blur/Light trails fixes it. Oh and I do hope you realise. The intro scene where the racers are lined up is extremely CPU limited. Either way I mentioned the game will be vastly CPU limited in many scenerios so if you're expecting your performance to double in every situation you're going to be extremely upset. I have to play the game @ 1600x1200 with 4xAA to even get my card completely GPU limited with a single card.

Fairly certain. I'm using the quality settings 67.66b driver. Might mention that this is the demo of the game, don't expect it would be much different than the retail finished version though.
The game play couldn't be better smooth as silk with great frame rates.

I think people might find it interesting that the 71.81 drivers allow you to globally force SLI...

This was possible in the cp of every 71.x driver (using coolbits), as far as I know, and, of course, with nHancer.

Hmm. Never worked for me... I've always gotten "Multi GPU rendering" Or "Single GPU rendering"

*Edit* I guess your right. I have always seen "Single and Multi GPU Rendering" with the coolbits install. How in gods name did I miss that? I havent worked with Nvidias control panel enough lately it seems.. I wonder whom we have to blame for that. *poke*

@ChrisRay: You can use the nvapps.xml with older 71.81 Drivers and with this Profile Value ="2430001" having real SLI Support on NFS:UG2!!! My FPS jumps from 34 to over 60 fps ;-)

Sazar. I currently am trying to get this title. Atm I dont have it. But I am also trying to get a few more titles such as Riddick, Halo, And Tomb Raider: AoD to update the comparison. I'm not sure which ones I will get but I promise I am working on updating this comparison with new titles. I'm really trying to focus on stencil shadowing, and shader performance of SLI in AFR mode right now.

See page 1 of this thread, about half way down Chris's third post.
