DOOM 3 QUAKE 4 PREY ID TECH 4 ENGINE

Recently bought myself a new computer. It’s a fast system. When I play one of these three games the environment stutters when moving around using asdw. When I look around using the mouse everything is smooth. It has nothing to do with:

-Keyboard or keyboard repeat rate (tested)
-Ingame settings; tried them ALL
-drivers; al my drivers are up to date and I have tried ALL drivers available for my system
-Bios is up to date
-system not overclocked
-compatible soundcard is in my system
-display is 2ms 740 bf
-no background progs are running
-nvidia controlpanel settings set for ‘use opengl specification’ but should work if set to ‘let the 3d aplication decide’

I think it has something to do with the game engine. These three games are all three opengl games. ALL my other games work fine as they should. I’ve been trying to solve this problem for almost a year and have contacted both nvidia and activision. They can’t help me.

Please help!! more people must have this problem

Drop the console, type gfxinfo which prints a lot of stuff. It will print GL_VENDOR = …
GL_RENDERER
GL_VERSION

so see what it says.
