It seems to happen to my dad's computer too!
I got a P3 500mhz,512mb SDRAM,GeForce4 MX440SE 128mb and the game is just fine if i put Graphics performance Medium,otherwise is a bit slow!
Anyway,sometimes the game accelerate at high speed(nothing uncontrollable) for quite a time,its kind of cool...
On my Dad's notebook P4 1.4Ghz,ATI Radeon 7500 the game runs fast(But i still can control the game)!Its just that the battles finish very fast... <img src="/ubbthreads/images/graemlins/silly.gif" alt="" />
