The compiler combines the vis leafnodes in your map in vis clusters, and using -fast vis the compiler only checks visibility between those clusters. I found that in some cases, this can still lead to considerable fps savings with a compile time of only a few minutes (and a visdatasize of 1.6 MB)
I'm doing that right now, with a few man vis areas, since the vis compiler virtually draws everything execpt for farplane culling of course. Right now fps is 30-60 with full vis, now I'm going to see what is like doing -fast. The man vis I did are in high traffic areas with 40 fps so I thought I'd spruce it up a bit. THose areas with 30 are mostly not in the main drag so I'm not worried about it...
