I got this annoying issue with my graphics in nearly all the games like: NFS: Most Wanted, S.T.A.L.K.E.R Shadow of Chernobyl, C&C 3, Silverfall.
The problem is that in the middle of a game I experience graphic lags like missing triangles and annoying polygons stuck here and there...
I have Leadtek Geforce 7900GT 256MB, and I've tried all the driver versions I could get, including the newest drivers.
has this always happened or did it just start to happen? If it just stared to happen try dusting the card and/or revert to the previous driver you had when the card was working. but it sounds like a heat issue to me
I hope you're right, but I've already tried to dust the card and it was not always so, and I've tried to install old drivers, nothing really helps. :(
