I'm running off XP, which is why I was forced to use High settings and not Ultra High.
18-25fps in game round abouts. If I look straight at the sky, I get around 50 haha.
On the start up part with the planes and that going through the clouds, it knocked me to around 11fps when the plane was close to the camera.
But yeah, minimum of 18, average of around 19 and max at around 25 within normal situations.
That is trying to play all on high, with a res of 1680x1050 on my specs
Oh, and CPU is at 3.2GHZ, not 3.6GHZ at the moment
I've forced it to run at a lower resolution now 1280x960, and it doesn't look stretched, and at that setting, on High, I'm getting 25-30-40fps
