The framerate in doom3 seems to jump constantly between roughly 2 values about
20 FPS apart. So my framerate jumps between ~30 FPS and ~50fps. This is
accompanied by game graphical stuttering. 

System:


3.8 GHz PhenomII x4 core AMD processsor
4GB DDR3 RAM
Sapphire Radeon 6950 graphics card


$yum info xorg-x11-drv-ati.x86_64
