Framerate drop and polymesh collision

[Pastaspace]

I've noticed that whenever a character controller (the player, or some NPCs) collides with a particularly complicated static object, the framerate drops to an absolute crawl.

Now, I understand why this happens, my main question is, how do I prevent it? Is there some way I can generate a polymesh/phy object for these models that's less complicated and less intensive, or something else?

Yes, that's correct. You should always use one of the other shape tools for this:

Polyhedron is a good one that works for most things.

I gotta ask then, seeing as polymesh causes drops so easily, what's it really used for?

This is usually the best option for buildings where each triangle in the visual geometry should be collidable.

 

I also think CSG use this type of collision. If you look at the CSG in-game (which get turned into models), you can see the triangles on the faces. For models, I personally would not use it.
