So I consider myself an intermediate mapper, but I've always had trouble with compiling times. This is probably because most of the maps I've been making recently take place in large outdoor areas and contain numerous buildings with windows, making it almost impossible for me to use areaportals or hint brushes. I've used func_detail as much as possible, but to no avail.

Any other ideas? Fog and editing the rendering distances for props really isn't an option right now. I'm mainly having issues with vvis, which tells me that there's still something I'm missing here.
