Ok, I have a question... I'm running on a 1.3ghz p4,64meg geforce4, and 256rdram. My conn. is 1mb/300+ cable. Is the main reason I lag like if I was running on a mac because of the low ram? I know the min. requirement is 512, but I wanna make sure that if I upgrade, it will fix the lag problem. So... Yeah, help plz.
