Same problem here
I disabled one core, but my frames never go higher then 10fps. settings set to minimum or maximum doesn't make a difference.
Got a
Geforce 7900GT/GTO
AMD Athlon 64 4200+
2GB Ram
XP
I can Fly Il-2 on maxumum Settings with 90+ fps, so I should be able to play TOW fairly good don't you think?
