Is there any difference between rendering 1000 identical images and 1000 different images? oops I meant question, not questions

Aside from having to bind different textures per draw I don't think so. I don't know if glBindTexture automatically checks to see if a texture name is already in use (and thus doesn't perform any potentially costly state changes), you could always perform a quick test to figure this out.

One would hope that BMax avoids renderstate changes so rendering 1000 identical images should be slightly faster than rendering 1000 different ones. Perform the test and let us know ;)

A related question: Does anyone know if there is any speed difference in drawing a single 1024x768 image, vs. 192 64x64 tiles (both ending up fully covering a single screen, with no scaling applied)

In theory the first way should be a little bit quicker, but it wastes more memory (because it would use a 1024x1024 texture)
