Are the buildings the problem?

Test and see if you can smash into the side of Westminster maybe?

Yep, they have, and the trees don't so you may very well be correct. A simple farmhouse is enough though

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
