Man half the topics started in the last couple of days are misplaced in the ESF Chat. They should be in newbie central...
Anyway u need a pretty high end system. Far over 2 GHz as alot of players with pc's of around 2 GHz have been moaning about low FPS and whatnot.
I have a P4 2.8 GHz and even my PC has fps drops if there are too many ki blobs stuck on the map, but nowhere near the fps drops some players experience. Then again I'm not running this game on the highest settings possible with Medium quality and a reso of 1024x786.
