Hi Robert, Hmm, I thought so too. It's not the texture functionality itself, it is (most probably) the pbo code that is causing the trouble. When I pretend that I am an Apple, i.e. the computer ( :-P ), and thus comment out the usage of the pixel buffer object, it runs fine.
This is all done on a modern nvidia (don't have access to the details right now), on windows, version 1.2 I believe (so not the cvs version). I will look into it some more when I have the time. Do you have any ideas in the mean time? best regards, thmx!
