OWA · 02-06-05, 12:08 PM

Great post Chris. Thanks for the effort.

PSYCHODAD · 02-06-05, 12:33 PM

Wow, nice job. Bet that took awhile to put together.

Yes Max FPS also went up. But I dont pay much heed to max FPS. Just AVG/Min usually because I feel its most important.

Attention UT2004 users. I managed to get around the performance barrier of UT2004 SLI. By default Nvidia has it set to an optimised AFR profile. When you'd enable SLI you'd see zero performance or worse. Lose it.. Obviously I was completely unsatisfied with this result. So I toyed around with it. And Viola. The most basic Split Frame Rendering mode produces a nice performance enhancement for UT2004.

*Edit* Removed as I have found problems with this game.

Veger · 02-08-05, 06:39 AM

wow, excellent information, good job chris...

blueworm · 02-08-05, 07:05 AM

Great work cris.
1 question, I take it that it is possible to hand write the profiles? And that the cutesy app is just for ease?
I am a linux user and we are still waiting for SLI drivers, and the whole profiles thing has had me worried.

Excellent work Chris. Now if you can get it working for Doom1, I'll be set!

Great job Chris, as usual. You are often, IMO, the board MVP.

eva2000's frames at 1600x1200 with 4xAA/16xAF illustrate precisely why I want SLI. The SLI min/average frames with GTs or Ultras are just too impressive.

Soon as I break down and get that new monitor it's all over for me

I'll have zero resistance left.
