Thanks for giving more information.
There are a couple of "beginners mistakes":
- Visdata size is pretty huge.
Seems like you use a lot of world brushes. Do you use func_detail for the small brush objects like the window frame, the tables (?)?
If not, you should really read some beginners guides especially about VIS leafs. ![]()
- Many point light sources -> try to use light_spot instead, and not so many in each room
- prop_static using dynamic props -> they won't show up in the compiled map -> use prop_physics_multiplayer for these
