[Bug 2038801] Re: Secondary GPU frame rates are held back by dynamic-max-render-time
** Description changed: + [ Impact ] + Secondary GPU frame rates are held back by dynamic-max-render-time as shown on this amdgpu setup connected to a 60 Hz monitor: main: 30 FPS main + CLUTTER_PAINT=disable-dynamic-max-render-time: 60 FPS https://gitlab.gnome.org/GNOME/mutter/-/issues/3070 + + [ Test Plan ] + + This is imprecise because many machines won't exhibit a measurable + difference... + + 1. Set up a dual GPU machine with dual monitors using an open source + driver such as amdgpu or nouveau. If you are using Mutter 46 or later + then the closed source Nvidia driver may also be used in theory. + + 2. In a Wayland session, check that the frame rate being achieved on the + monitor connected to the secondary GPU is at least that of the refresh + rate. + + 3. Add CLUTTER_PAINT=disable-dynamic-max-render-time to /etc/environment + and reboot. + + 4. In a Wayland session, check that the frame rate on the monitor + connected to the secondary GPU has not changed (didn't get better) after + the environment change. + + 5. Remove the change from /etc/environment. + + [ Where problems could occur ] + + Anywhere in frame scheduling and frame rate performance, since that is + what changed. + + [ Other Info ] -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to mutter in Ubuntu. https://bugs.launchpad.net/bugs/2038801 Title: Secondary GPU frame rates are held back by dynamic-max-render-time To manage notifications about this bug go to: https://bugs.launchpad.net/mutter/+bug/2038801/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
