Fixed by the CB_SHADER_MASK fix.
Hurray,
r600g (Turks) ~10% performance drop for Mesa's 'objview' is _mostly_
fixed.
Mostly 'cause it is NOT on par as before (the 'broken') version.
E.g. 'buddha' was stable at 600 FPS (see below).
Thanks,
Dieter
Without fast clear: with new fixed version:

Taken from former posts with Michel (about enabling DRI3/glamor):
Mesa-demo's 'objview' show this:
bobcat.obj: ~790 => ~1048 fps | ~25% with glamor ~1388 fps
buddha.obj: ~370 => ~527 fps | >33% with glamor ~600 fps
bunny.obj: ~530 => ~720 fps | >25% with glamor ~863 fps
GreatLakesBiplaneHP.obj: ~435 => ~593 fps | >33% with glamor ~687
