I tried the following: 1) Changed viewport to 1/2 and 1/4 of original size - no effect. 2) Changed all textures to one,so there is just one texture binding per cube - no effect. 3) Culling is on
For all other points please take a look at my code which is in the forum post I linked here, as I am not sure how to do all of them.
