Are you using cg_subtract a lot? cg_subtract is the devil for new GTK radiant users. It is so easy to make brush architecture with cg_subtract, but unfortunately, it takes the soul of your map. using excessive cg_subtract can cause tiny tiny brushes that the compiler doesn't know what to do (two tiny brushes). This causes poor frame rates (the game still draws them) and can increase the size of the bsp.
The pict you posted might be from one of those little tiny brushes. It was small enough to show up in radiant, but the game cannot physically draw it.
Only use cg_subtract
when you have to or not at all. If you have to use cg_subtract, make sure you know what you want it to do, and then double check that it actually did what you wanted it to do.
For a really good rock wall tutorial, go here:
http://www.simonoc.com/pages/articles/rockwall1_1.htmI think all the SG mappers use or have used this method. Its hard to get used to (still working on it), but they come out beautiful.
It is a very good tutorial because you have to manipulate brushes by hand. Once you get used to doing that, cg_subtract will be the past
