So...Quake 4 for the most part runs without a hitch...but...

I can't help but notice that when there is a flame or something that involves a standing fire, like flaming debris, the effect is something like a mirror...it just magnifies the area around it...also when I zoom in with the machine gun scope, it shows whatever is over to the left of it...it's still technically pointing at what I'm aiming at, because when I shoot, it still hits what I thought I was zooming in on...it's just like I have a cockeyed scope...is this a simple problem that can be fixed by messing with some graphical options? or perhaps something more sinister? By the way I have a brand new Macbook pro with the 2.4 dual core and 8600m graphics and 2 gigs of ram and all that goodness
