Yes. Let's play TTT on gmod tower's lobby!
Yeah though.
If you take one of TTT's maps that runs pretty poorly into sanbox, and enable sv_cheats, you can do mat_wireframe 1 to test optimization. If you see the entire map being rendered at all times, even though you shouldn't be able to see parts, It's not optimized well. (For instance, go into the FRG's event map, and do this. You will see parts of the map aren't rendered until you reach certain parts.)
