SLI Question

[GWarrior]

Hi hows it going ?

my laptop has dual 8800gtx in SLI

in my Nvidia control panel SLI wasnt enabled !

so i enabled it & restarted .

COD4 looks amazing , grid race driver looks better, plays better more FPS ,

but GOW plays worse lags and freezes , why is this ?

with the SLI disabled did that mean i was only using one GPU ?

Sorry to ask so much

Yes, with SLI disabled you use only one GPU. Running SLI is still very finnicky... It can look amazing, or it can make your computer overheat and become terribly unstable. I have had a few weird situations like you:
Guitar Hero 3 is really "laggy" with SLI, but smooth as silk with only 1 GPU enabled.

Oblivion for some reason won't even play with (or without?) SLI (Can't remember which)

Without SLI enabled, Crysis won't work..

etc...

Of course in all these cases once I flip the setting, it magically begins working :/

GOW = may be because of Microsoft? J/K.

The problem with a SLI notebook is that the vendor(s) doesn't release driver updates fast enough unlike the desktop counterpart. Each notebook vendor has to customize the driver, in most case, they don't even provide an update until 6 months later.

These guys covered the most likely problem. Try a bunch of different drivers and/or turn off SLi while running GOW. You can do that via the nvidia control panel. Keep checking for newer drivers.

maybe why frontlines fuel of war wont work either

thanks for your help guys

I got a beta invite for that game while I was still on SLi and it ran horribly if it would even load.
