Im sure it is the game, ppl with great system are having unstable FPS.
Im running a prity nice system although its not the best.
TB 1,2 gig
Solteck SL-75KAV/-X mainBoard.
GF3 TI200 (at TI 500 speed)
256mb SDRAM.
Most of the time im gething 70+ frames a sec, but at points it falls down below 20.
Im sure it has something to do with the game.

You are my adversary, but you are not my enemy. For your resistance gives me strength. Your will gives me courage. Your spirit enobles me. And tough I aim to defeat you. Should I succeed, I will not humiliate you. Instead I will honour you. For without you, I am a lesser man
