OK, I am doing some optimizations on my 3D engine... There are places where I have many meshs, and can probably combine them into one... of course, just doing addmesh seems to make no difference in speed whatsoever... but I have heard that combining the models manually so that they are all on one surface actually does speed things up.

Is this true? I haven't found a function in the code archives or on blitzcoder to combine meshs to one surface, so before I spend an afternoon coding one myself, it would be good to get some input.

Also, what are some other tricks for squeezing out a few more frames per second.
