Well I started having an issue of mayjor fps loss in most of my games. FOr example in Tribes 2 I was running 100-110 now I am running 12-48. I am so lost on what the cause could be. System: P4 1.4 MHz 512 MB of Rambus RAM 160MB/512MB in use. 64MB G force 4 TI 4600 ( 40.72 Detonator Drivers ) EDIT: Windows XP with SP1 (forgot about that) NOw nothing has changed from the time I was getting 100-110 to now where I get 12-48. UT2k3 is running anywhere from 30-60 just depends. Thats ok with me but my recent loss in Tribes 2 baffles me. The only thing I can think it may be is all the heat inside my PC. I have one fan and it is for the P4 only and is sheilded so it's doens't cool the other areas. I took the side off my case and will try that when I get home from work tonight. Just wondering if anyone else has any tips. Thanks!
