Less efficient than using the hardware texture sampler filtering > capabilities, though certainly doable. Also, it can't be accelerated on asics with limited shader capabilities. It'd be nice to handle it in a way that's friendly to more limited hw as well. -- Configure bugmail: https://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug. _______________________________________________ xorg-driver-ati mailing list [email protected] http://lists.x.org/mailman/listinfo/xorg-driver-ati
