I still havnt been able to figure out after much testing what might be the cause of this. I play TF2 and WoW regularly and with my spec's ive been able to play both of these for many months on full settings and never notice any video lag. my specs are Intel C2D Q6600 2 gigz OCZ titanium ddr2 BFG 8800 GTS OC 512 500 gig raptor 7200 HD Ive defragged, tried different drivers, tried rollbacks. Nothings seemed to fix my vid lag though. In WoW i can usually run fine but if im in a big pvp battle i go down to like 5-10 fps. In tf2 i get constant noticable drop in fps if there's any firefighting going on. Neither problem was there before 2 weeks ago. Ive posted on my wow guild forums and my tf2 clan forums and everyone seems as dumbfounded as me. If the vid card was going out ida thought it'd be noticable constantly and not just heavy video situations. Any help would be appreciated!
