Tested. Great map yet again. But there's one major flaw: That's 1024x768 (although windowed) on a quad-core, HD4850 powered machine. 21 fps is just unacceptable with that (my lowest when rendering whole zs_stormier_v1 is 50 fps). I suggest you cut down on the props, maybe even take away the whole central building and turn it into one brush, and remove one of the small water lakes.
