Ah, I guess that was that memcpy I always saw in moveIn / moveOut ;)

Ah interesting, because I saw 4x better performance with intel-2.1.1 /
With this configuration the putted data was just memcpy'd to vram, but
now it seems to be a readback->put->upload cycle :-/
I'll try to find a small test-case and report a bug.

Yes, I also really hope they merge it back soon.

Thanks again, Clemens
