Quake-style games have options like gl_swapinterval and gl_ext_swapinterval but they do not seem to do anything. Honestly I don't even know what they should do, but on other platforms they used to disable vsync on some cards. > > The code in the ddx you are asking about has nothing to > > do with the GLX vsync/vblank extensions; it is there to prevent tearing on > > GL buffer swaps. And it hurts performance not being able to turn it off without a patch. I like tearing! ;-) Btw. are we still on-topic on this bug when the actual fix for vblank_mode was already committed? -- Configure bugmail: https://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug. _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/dri-devel
