even on LOW settings, i chop on p4 2.6!!

[eliasryu]

really bad chop, on lowest settings
running:

p4 2.6
1gb ram
ati saphire 7000 64mb <- i know it sux

still should be able to do something better than LOW for my settings.
looking at my system specs while the game is runnings, it's using 97~99% of my cpu!!
only using about 300mb ram tho
any suggestions? ran virus scans, ad-aware, didn't defrag, but the hdd barely lights up during play.
also crashes a lot in heavy combat areas, almost always
