Hi, I am wondering how expensive it is to change the current texture being used by OpenGL via the glBindTexture command? Would it be worthwhile organizing a mesh ordering it by which texture it uses (like grouping by texture type)? I haven''t had a chance to test the performance hit properly of changing the texture rapidly.... Thanks, Cel

Delete your other two posts. Short answer: Yes, it is worthwhile to avoid texture changes.

Texture binding is expensive. You can gain quite a few fps by avoiding needless texture swaps.
