Optimization of moving brushes.

Hi guys, i have a cabin made of func_physbox, it is fairly complex and when it is destroyed (by explosions) the frame rate drops to 10 (and my machine is a real beast). I have been informed there is a way i can improve the performance, is this by changing them to func_physbox_multiplayer. Will this change the way the game loads so it knows that the brushes are not static from the beginning meaning there is not so much of a peformance hit when the cabin is hit? Any help would be great guys. Thanks.

Func_physbox_multiplayer is designed for less network lag in multiplayer games, it wont affect framerate significantly. How many physboxes are you using for this cabin? If theres a lot of them, explosions affecting them will kill your framerate. Try simplifying the cabin, merge some physboxes together.

What if i can't simplyf the cabin, it's part of my boat map so it needs to look as it is. Is there not a way i can improve it?

making parts of it as wall toggles, and having them disappear, while other broken pieces(again toggles) appear already in place a second later, may save some of your fps. it wouldn't look great to anyone close enough to see it, but as there's an explosion happening, no-one should be allowed to see it and live anyway.
