Not only DRI3/XPresent is performant, but with xorg-x11-drv-nouveau (xf86-video-nouveau) "v1.0.12" i.e. current git provides tear-free experience on Desktop. Guys, what about "[ANNOUNCE] xf86-video-nouveau 1.0.12" i.e. actual v1.0.12 release? xf86-video-nouveau-1.0.11 dates back more than 1 year, 03-Sep-2014 http://xorg.freedesktop.org/archive/individual/driver/?C=M;O=D _______________________________________________ Nouveau mailing list Nouveau@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/nouveau
