As a rule of thumb, I don't like my level mesh to go above 10,000 polys - but it's fairly simple geometry and it's pretty much visible all in one render (no occlusion) with a distant camerarange involved.
Of course surface count is a killer, but my feeling is that Blitz's 3d rendering is not overly quick (compared to other engines) - so it's better to underestimate/optimise I guess.
