My system is old but should have enough juice to run these games - FIFA 08,UT 2004,Simpsons, MOH AA. I get stutter on all these games, with FRAPS enabled i can see they all run at 60FPS but then stutter and dip to 15-20 then back up to 60 and son. Interestingly, I can run the bioshock demo and it only performs badly when an enemy is on screen, almost replicating this stutter effect. I have tried various drivers, disbling my onboard sound etc all to na avail. Surely I should be able to run the above games quite comfortably at 1280x1024....apart from Bioshock that is? Any help much appreciated.
