Hey, I'm having a problem with all of my games, I've googled like crazy but still don't know what the proper cause is or how to troubleshoot but I suspect it's a CPU issue.
Most if not all games, especially newer ones, have these constant stuttering hiccups, as if the game cannot load something quick enough. It happens more when there are NPC's around. But it has nothing to do with framerate, my FPS remains high at 60fps and above but it still happens.
It seems like a CPU issue because I can put the video settings on a game to the lowest settings and it still happens regardless. However I also found some google results saying this is a particular issue with the model of video card I have, so I'm not sure.
Windows 7 64 bit (with all recent updates)
CPU: AMD Phantom 2 quad core 955, 3.2ghz
GPU: Radeon HD 6870 2gb (drivers updated)
Ram: 8gb ddr3
PSU: Raidmax Hybrid 2 630 watts
I think Metro 2033 is the worst offender out of the games I've tried, it's basically unplayable, but my specs surpass all of the system requirements. Even system requirements lab says I reach the maximum recommendation. When I've played The Saboteur, while driving the game often has to literally stop and load the textures on the floor before you can continue driving, it's crazy.
So does anyone know how to fix this or what could be causing the problem? Thanks.
My motherboard is Biostar A880GZ. I ran the game, then alt-tab (because the game is in full screen), then checked the clock speed in hwinfo and the GPU speed is at maximum, but then it goes back down to minimum (because game is no longer full screen).
I checked AMD site but I have the latest drivers, I've tried uninstalling and reinstalling the drivers before but it still happens.
I recorded a video of how it is, this is at lowest settings in-game, the framerate is high but the stuttering still happens.
