laggy map

[Seraphim19]

hey im makin a map and every time i look at an area (in game) it gets real laggy. i dont get it cuz its not that packed of an area. it looks like this:

why would this be a laggy place, all the sudden my FPS drops to like 5 and i cant do much. whats the problem?

why does it lag whenever i look towards it?

Check all your entitys and if that doesnt work just try deleting 1 piece at a time and see if its 1 thing fugging up your map. also your brush might be massive and that could lower the fps(although it looks small from the ss)

Did you get any compiling errors? Because it sure sounds like you've got a leak some place. I don't know how it's done now but you used to just load up your point file to track it down. You might look that up and check all you entities, especially your func_brush's.
