I havent had much time for gaming recently but now i've started again im having a very strange problem with stuttering. The computer was freshly formatted last month, no junk installed and all (relevant) drivers up to date.
Its an E6300, 2gb pc6400, x1950pro with an LG226WTQ as my monitor.
Neither CPU or RAM usage reach near full load, temps are fine but this is my problem.
In both GTR2 and rFactor my framerates are >60, sometimes around 100 but there is a definate noticable stutter (not tearing) thats really distracting. I would try other games but im confident there is something wrong because ATI Tool's 3d window test reports >400fps but has quite a large stutter
