Are the buildings the problem?

Another weird thing is that my old Core2Duo is running at 20-40 percent load while buzzing those peasants The collision detection ought to be in the CPU so that should push that up in those cases one might think? As it is now it seem extremely GPU limited (which may be true with that GPU), but being at below 20 percent as I am at some times on that old CPU? Feels good though as the opposite would be a lot worse while optimizing!

EDIT: having said that the CPU load was "measured" using the Logitech G510 lcd app for performance monitoring. Not the sharpest tool in the shed

I think you're right, it definitely seems GPU-limited. I get good FPS (average 60 over land with medium/low except for models (high). My HDD is not being accessed much, my CPU is not struggling at all (and is using all cores by the way) but the GPU is fully stressed at 100%. If SLI was supported I'd just get another GTX480.

The stutters are the real problem for me. I can get good FPS but it is not at all smooth. Just wish I knew what bit of hardware is responsible...

Oh, and do you have a mirror on your plane? Turn it off! Instant FPS jump of 60 to 80 for me.
