I just built a system (for the first time yay!).
Someone told me he had over 30 fps with a Ti4200 and Athlon XP 2200+ in UT2004. Since they say the Duron 1.8 GHz is really a reconfigured Athlon XP 2200+, I decided to try the same thing. Well, in some Deathmatch maps on high settings, I hit up to 90 or 100 and rarely get down to 30 fps. So, I think I did everything correctly.
Anyway, what did I do? I wore a T-shirt so I could my forearms wouldn't be covered. I rested my forearms on the metal part of the case while I was working with the motherboard. As a matter of fact, I tried handling things with one hand while trying to constantly touch one hand on my case all the time.
They say before you start, you should touch both hands on the metal part of the case.
