My home gaming machine has an AMD Athalon 1.4GHz, 512MB DDR 2100, and a geforce3 64mb, and I can get UT2004 to run at 1280x1024 on normal/low settings across the board, 12 bots, any map, no problems. The only frustrations I run into are that the game loads really slow, and that it closes slowly. That's just 'cause my system is slow. Otherwise, besides not being able to have the max settings on and full-fog, I'm fine.
