I did wonder about the OpenGL command buffer limit -- any way to verify for sure that I am hitting it?
I would be surprised if that's the case, though -- it's not a real complex scene, maybe 3000-4000 textured triangles. But I'll admit to being almost a complete novice where OpenGL is concerned... The various meshes are all done with glDrawElements(). 95% of this is in the cow mesh -- same mesh drawn w/ different transforms, and different textures bound each time. The mesh itself uses ~54k of memory for vertices + normals + tex coords. How big is the OpenGL buffer? seems like it's got to be significantly larger than that.
