FPS issue

Well never thought that i would have a problem that would stump me with FS9.
I have my frames locked at 35FPS
Any ways for some odd reason my FPS won't get above the 20 FPS mark. just last week i was able to play at 35
I reinstalled but even at the default settings it hangs at 20FPS. every once in a while it'll pop to 26 or something but other than that it just stays at 20.
any suggestions?
