I've gone trough the first couple of missions. This game must be played by anyone remotly interested in FPS. I played lights turned down with big headphones and I'm scared (ar in really scared). The atmosphere is unrevaled.
The script is nice too and the gameplay, if not overly complicated, is tight and responsive. Now the best part, is that I've played with these settings on my rig :
800x600 with high details and every other option on (minus AA and Vsync) and I have yet to experience any slowdown. Maybe my FPS can go sub 30 but only for such a breaf moment I am not even sure it slowed down that low.
P4 2.8C (Not Oc'ed)
1 gig of ddr 3200 (2X512 with hyperThread) (Not Oc'ed)
A very modest Radeon 9600 pro (Not Oc'ed)
Onboard sound.
Long live Carmak for doing an engine so optimized I won't have to upgrade vid card yet ! Thx
