im averaging about 45-50 FPS on both SP and MP (with full version, not demo) with :-

AMD Athlon XP 1600+
256MB Ram PC133
Guillemot 3D Prophet
37 GIG Of Free Space

im pretty dissapointed. the only let down to this game is the shitty FPS you get. exactly the same with RTCW.

i would hate to see this game running on anything below a 500mhz cpu. my bro is really struggling on his Athlon T-Bird 1.2ghz / 256mb ram / 64MB Shared graphics (SIS Chipset). granted, the graphics is causing a bottleneck in the system and really holding its potential back, but still, this game is practically unplayable on his system. whereas he gets quite good Performance with Max Payne.

OPENGL SUX !!!!!!
