Splinter Cell Display Problems!!!!

Not sure if this is related to Open Gl or not, but I recently upgraded from a GForce 2 V/card to a GForce 4Ti 4200 V/Card, and now when I play Splinter Cell, there are like small spots on the screen, like little “tingly things” (very annoying). I also have Ghost recon installed, and when I played that,I got the same problem, but rectified it by lowering the “z-buffer” settings from 24 bit to 16bit (this is in the game itself)…but there is no such setting in Splinter Cell…Does anyone know how I can adjust this setting for Splinter Cell? i suspect this is the problem…

Splinter Cell uses the Unreal engine…

That’s DirectX
