I have an AMD Athlon 64 X2 Dual Core processor 4000+ ~600MHz and an Nvidia GeForce 8600GTS with Vista Ultimate Edition Installed and just recently, seemingly out of nowhere, the games that I was playing now run MUCH faster, like playing it in fast forward. I have AMD CoolnQuiet turned off, I installed the AMD Optimizer and still no success. The games I've tried running are Mass Effect, Portal, Assassins Creed, and Crysis. They all run way too fast. Strangely enough there's 2 games that don't run at super speeds: Ragnarok Online, and Oblivion. I have no idea what caused this as I haven't changed my hardware and I have no Idea how to fix it. I have Windows, all my drivers, and DirectX fully updated if that helps...
