noticed something interesting yesterday.
I maxed all the sliders out and had FPS of around 7 when sitting at the isle of Man airport (I have a 2.44 quad core, 4gigs ram, 8800GT crad). I then increased my screen resoloution from what it was (forget which) to a higher resoloution. FPS shot up to 14 fps.
I wondering if this has something to do with using a widescreen monitor?
