Not a good idea. Game play really sucks if you use these tweaks. If you use the fps tweak, everything runs really fast. If you use all the tweaks (including the one that fixes the game play going really fast) the game will really slow down in graphicly intensive and populated mass combat areas. The system I'm running Quake 4 on includes:: 3100+ Athlon 64 (Socket 754), ASUS K8N nForce3 250 mobo, 2x512MB PC3200 DDR-RAM, Geforce 6800GT, Audigy 2 ZS, 160GB SATA HDD.
