This was wonderful
easy to find an estimate of how much poly you should render on screen at maximum in your games, 59-60 fps with 216k polys
with a HD3870
intel e4300
2gb ram in windows vista
just tweak the vegetation codes and double the amount of trees rocks and bushes, and increase distance to 5000 and you get a great view of polys :p
300k polys at 25 frams :p quite a large fps drop there :p cpu load at 60% on each core while running, gpu I bet running a great deal more
