Does the number of brushes and faces significantly affect performance? Or is it mostly the filesize that suffers?
More brushes = more filesize
More faces = worse performance
FYI I’m talking about situations like if I have a brush and cut it into a bunch of brushes.
That’s okay to do, as long as you func_detail the smaller/more comlpex brushes.
No, it won’t.
Yes it will.
It improves framerates overuse will not help though
This will work better.
This, plus messing with Map -> Load Portal File will help.
Also try typing these two commands in console to see how visleafs relate to which brushes are visible.
mat_wireframe 1 mat_leafvis 1
