Well, the game is very playable at low settings - not nessacarily with a uber hax tweaked cfg, just some minor tweaks like disable shadows and some stuff, mostly cut out of other peoples cfgs. It gets good fps, with noone in a server on q4dm11v1, when I look over the edge on the first laucher pad to the side (towards rail gun) it drops to about 50 fps, but the q4dm6 map someone made which is 17 pages long, which is 20fps.
What do you think I should do? I heard about it being CPU Sensitive, and it limits fps, like in UT2K4. Personally, I think its the 6600GT holding my FPS back. Whats your opionion?
