I have been having a very odd problem with my videocards where I will be getting like 45FPS in Crysis, but it feels like 15FPS or so. After doing countless hours of research, formatting, upgrading to Vista, I finally stumbled upon two articles that explain exactly what I am experiencing. Unfortunately, there is no fix. I thought I would post these articles (even if it is slightly old) so at the least I could show people that are experiencing this "phenomenon" they they aren't the only ones who have this problem (like I thought I was). Anyways, heres a short excerpt from the article: Heres the links: http://www.pcgameshardware.de/aid,6..._-_From_micro_stuttering_to_macro_stuttering/ http://www.pcgameshardware.de/aid,6...ce_gains_from_current_multi_GPU_technologies/ Pretty interesting IMHO, too bad I have this problem though :\. Edit: I did a search to see if this was posted earlier, and it was. Sorry mods .
