At least here I have a couple of apps reading back from frontbuffer, and performance on i945+2.13 is horrible. No idea if it would be worse on SandyBridge if access is uncached, but even slower would *really* hurt. - Clemens _______________________________________________ Intel-gfx mailing list [email protected] http://lists.freedesktop.org/mailman/listinfo/intel-gfx
