Hello. I am having some odd issues running games on my machine. World of Warcraft reports that it is running 60fps on the ingame fps counter with everything maxed out on ultra, but goes insanely slow when ever i turn, but when walking straight it is fine. Also, I am getting some HEAVY artifacts when I turn on antialiasing. This occurs in Skyrim as well. I'm not sure if this counts as slow fps, but whenever I'm walking it does the same thing as wow, however every few steps it will freeze for a second, the nreturn to normal, then freeze for a second again. Also, Skyrim automatically reccomends High instead of Ultra.
I think it is worth noting that this did not used to happen, but only happened after I was having issues with my pc crashing, then I blew everything away and completely reinstalled Windows 7, and all of my drivers. I really hope someone can help me, and I really appreciate any input. Thank you!
