This is a great update for the current Smokin'Guns beta testing engine. This great updated map demonstrates how farclip can improve FPS frame rate !! If you still got our v1.1b4 update, get this add-on and unzip it in your "smokinguns" sub-folder, next to other PK3 files. You can also connect to a beta server with autodownload activated...
There are lots of little black brushes in this map!
I thing this is a bug...
