SLI issues!

post #1 of 15
Thread Starter 
Hey guys...been trying to play a few games , and something very strange is happening .....for example crysis......I would be playing and gettin avg of 50 fps...then the next level loads , and it then goes down to like 25fps....kind of like the SLI is turning on and off???.......


also in the game grid , SLI works when its loading the map , my FPS are double to a single card , this is also like this in the main menu , but when it actually comes to playing the game and racing , i get one card speeds...as if sli aint working again???...

Bioshock works fine 100% of the time , HL2EP1 , portal also use SLI perfectly......just these two games?

any help would be appreciated!

GRID and Crysis are system hungry games..

I play them boath at 1680x1050 Crysis with all settings H and No AA i get about 25-40FPS

Grid I play with everything highest and 8XMSAA and it runs the game min 65FPS, if i turn up to 8XQAA it will lag a bit..

in nvidia cntrl panel select.

All AA AF settings to App Controlled
force split frame rendering 2
And Multi display performance mode

Hope this helps..

if not try http://forums.slizone.com/ lots of good SLI veterans over there

It may be software related... But seems odd... Have you tried uninstalling and reinstalling driver/cards??
