Concave Mesh performance hit

[Grunge]

Hi All,

Im expereincing a problem that I hope you can help with, we have an entire level of our game working quite well, untill this morning when we added 2 concave meshes to the world, these are about 60 primitives each and have knocked our game down from about 30fps to maybe 2fps.

Any one got any ideas of some optimisations we can add to these or any clues as to why 2 concave meshes would kill the frame rate so badly?

Ta in advance.

Not the best 1st post, turns out our artist had added stuff off screen that was killing the frame rate so it's not the physics..


Sorry all.
