I forgot to mention, there also seems to be a bug when entering full screen. While the screen aspect remains to whatever it's using by default, the mouse gets stretched to your screen, (16:9 in my case). So, for example, if you're in full screen and you try to put a turret on the sides of the screen, or try to click a button, you'll have to move farther to the left or right than what appears on screen.
Also, have you considered using LOD models when zoomed out? I'm getting framerate drops when zooming out on larger maps, and when it dips too low, trying to use fast forward ends up slowing the game down more.
