Sometimes vista is extremely slow in games ( I tend to say Vista has periods as it mysterically is fine for three weeks and suddendly slows down for a week, easter egg?).
I had FPS 5 for a week but then I went online one day and my FPS was 60...
It doesn't matter much if you have desktop computer or laptop.
Check the heat of the parts every now and then with SpeedFan to be sure it's not the problem causer.

Vista? I wrote Windows 7!
