I love this game,but I can't completly agree that this game runs smooth(at least for me.)
The problem I seem to have is that the ground feels choppy or jerky when flying(speedwise that is, not graphics.) I'm running this game on a q6600 @ 3.0, 4Gb Mem, 295gtx on vista 32bit. I just read the FAQ and I'm going to try to fiddle with the graphicsfile when I get home.
When looking at this video
it all seems to be very smooth. Going to test to run FRAPS to get a FPS value(or if anyone knows how to turn this on in BS, please inform me.).
