A couple of demo problems i found...
1) The Graphics Options, where you can change the screen resolution.
I see all the resolutions listed, but the max refresh rate is 85htz. My desktop resolution is set higher at 100htz. Why does the demo limit my refresh rate.
2) The space battle section in the galatic conquest.
Some units have a strange ability to keep drifting, even after I tell them all to stop moving.
