Reduce the number of loop iterations
Does this patch impact performance at all?
No noticeable difference with you patch. BTW I did repeat bisecting and it again showed commit c298bab60ea63882f34825a35cbc60f662783e64 as the one introducing this slowness. So indeed your analysis in comment 17 looks right. I wasn't able to bisect any further slowdown with glsl2 merge which Sven mentioned in comment 24. However we might have different setups because for example I don't have any troubles with libtxc_dxtn.so
