>>38676303I mean, it's still pretty simple geometry.
The issue is, since there's so many windows that enemies shoot through, so much of the interior of the building has to always be rendered in the chance players will look inside and see it.
Basically, the more that COULD be seen by a player at a single moment, means it all has to be rendered at the same time.
So pure interiors are okay because they're hallways that the player can only see in two directions. Outdoors are worse, and mixing indoor and outdoor areas is the absolute worst for the engine.
>>38676109I feel you, brother. The struggle I always have with goldsrc is I want to add too much- do too much, and it either just isn't possible, or even if it is, it's too taxing on the 20 year old engine. Gotta force myself to make the level geometry simpler and remove details I'd rather have.
