Since i love Fallout i ignored all the complains about Rage and ordered it. Today i recieved it and yes, my weekend is saved

But to the bad news. Is the game locked to 60fps only? If so, why? Both my head and eyes is burning after 30min since i'm used to play with 120hz/fps
And i've also notice white glitches in the graphics every second. It almost seems to be an graphic bug. Everything is flickering and it's impossible
to play more then 20-30 min before i (my eyes) needs an break.
Is there any fixes to this? Or is it just me who has this problem?
EDIT: Ohh almost forgott. I have the newest drivers for my HD 5970
