I got a dule CPU, and a GForce7800GTX, with 2gig DDR of ram, and 2 HD I can run BF2142 on full with the resolution at 1280/1024 with only slow downs when I'm in the middle of an arty strike. But thats not going to be a big issue in a StarWars mod. It's only the dust that makes my PC crap out, every thing else in the game runs super smooth and looks great!
BTW we all get some FPS drops, in Titan mode when the titans are only 200 feet apart, and everybody is poding back and forth with the guns on the Titans blazing. But thats mainly Server lag. Even on my Lan server I get no lag from a 32 player Titan game.
Long live the Empire!
