I get frame skipping, or stuttering, in most of my games, and it's driving me crazy. It's like whenever I'm moving in the game there's a minifreeze every second, even though the framerate is a solid constant 60fps. If you don't know what I mean, here's a video that shows it: (The video isn't mine but I get the exact same phenomenon) Quick answers to some of the generic questions: * Yes all my drivers are up to date. * Yes all the temps are fine. * It's not a PSU problem, because I replaced the PSU with a good quality $170 more expensive one and it didn't make any difference. PC specifications: CPU: i5-2500 GPU: ASUS GTX 580 direct cu II RAM: APACER 8GB 1333Mhz in dual channel mode PSU: Thermaltake toughpower 850W Mobo: intel dh67cl Please I've been looking everywhere for an answer for 3 months now, and still nothing. I can't even play street cleaner simulator without this annoying frame skipping.
