I have a core i7 @3.4Ghz + Geforce GTX 560 ti. In the scene in the video I get ~196 fps. Shadow quality can be reduced if you need more performance and of course shaders can be disabled altogether.
Hah cool that's the exact same specs as my computer. What's your case?
I wish environment settings were host only.
I can't see them not being host only.
does the sun use the game's real east and west?
In the video I think I see him rotating the sun on the horizon, so I'd assume not.
edit: one of the controls is solar azimuth, so yes he was rotating the sun on the horizon.
