I've been messing with this for 2 days now and can't seem to find a solution. As far as I'm concerned there's a way to enable SLi for Dirt 2. Today I downloaded the latest driver 196.21 that has SLi support for Dirt 2 and it still doesn't work. My second card sits at idle temps and although my fps went up by about 5, that's only due to a better driver. I can't seem to figure out how to enable SLi, even though avg fps now is 59 running only 1 card, I can use some extra for more AA and such. Anyone?
Thanks for the link but it didn't help me much, thread is old and the new driver has been released with a so called support for SLi. I'm wondering if anyone's got it to work without much trouble.
