Here some tweaks to improve framerate.

S!

Tested the "no SSAO" on my rig. Instant jump in FPS and really can't tell the difference in IQ. Make this an option in GUI..would be better to have more options with proper documentation what they do.

This mipmap thing. You notice it easiest with lower building settings how the houses change from "non-skinned" to detailed and back depending on your position. And the use of huge textures..why? With a bit of work you can make things look good with less size too..or?
