https://bugs.freedesktop.org/show_bug.cgi?id=103486 --- Comment #5 from Andy Furniss --- glxgears is no good for this one, it doesn't seem to really get fullscreen. I don't use a compositing window manager, if you do I guess you'll need to set it to disable compositing for full screen. To seeing if I can get full screen tearing I would use something like - vsync720p60.mp4 - https://drive.google.com/file/d/0BxP5-S1t9VEEejRkMzlRck5GNTQ/view?usp=sharing With no compositing and TearFree off I expect to see tearing playing like - vblank_mode=0 mpv --vo=opengl -fs vsync720p60.mp4 For the frame rate capping issue I noticed with xonotic. In the settings menu, video tab, make sure vertical synchronization is unckecked. On the misc tab check show frames per second. When on the menu screen fps should now be seen lower left. For "bad" it's 120 for good it will be 200. Running a timedemo will also show being capped at 120 for "bad" but unlimited for "good". -- You are receiving this mail because: You are the assignee for the bug.
