Nvidia 6800GT SLI investigation

[ChrisRay]

Alright. Here you go. My results echo yours. But I made a little graph jpg for you to make it so anyone can see. I noticed 3dmark2k1 was using an AFR 2 SLI compatibility bit. I have a suggestion that may or may not help. As far as I know AFR2 profiles use the SLI connector differently than standard AFR profiles. So try using a standard afr SLI rendering mode and tell me if that changes anything. This test is exceedingly bandwith limited so it wouldnt hurt to try.

thanks Chris for the confirmation, nice little ladder of results there ( all tremble in front of the 7800's fillrates ! ) .

I've tried all Sli modes and no joy. must be a bug I guess as it works fine ion 03 and 05.

Does it still pick up all settings from that file in Windows32 ? I might try looking at that, after that I will give up and see if it corrects with later driver revisions.

Regards

Andy

Heh ya.. I've always been impressed by SLI fillrates.. I just wish I could have been more help to you. At least you know its not exclusive to you. The profiles are picked up from the nvapps.xml file in win32. But keep in mind. If you change it manually. You need to reboot because the profile isnt loaded into system registry until a reboot.
