This concerns a multi monitor setup with different refresh rates (e. g. 1 with 60hz and 1 with 144hz).
The text below is part of the linked article. If you have both nvidia and picom installed, check both sections.
NVIDIA (propietary)
- Open
nvidia-settings
- Go to 'X Server Display Configuration'
- In the bottom right, Click on 'Advanced...' if it says 'Advanced...'
- Make sure anything regarding 'force composition pipeline' is checked off
- Make sure you selected the highest refresh rates possible. You can either select it through the settings, configure it with
xrandr
or with your DEs Display Settings, is applicable
picom
- Make sure to start picom with
--no-vsync
Misc
If it still doesn't work, try settings these environment variables:
CLUTTER_DEFAULT_FPS=<your highest refresh rate>
__GL_SYNC_DISPLAY_DEVICE=<your highest refresh rate display>
__GL_SYNC_TO_VBLANK=0
Find the DISPLAY_DEVICE name with xrandr | grep connected
Add the text block above to /etc/environment
(Tip: Use EDITOR=<your editor, if EDITOR is not set anywhere else> sudoedit
instead of sudo nano
or sudo vim
)
-> sudoedit /etc/environment
I don't seem to have a tab named 'X Server Display Configuration' 🤔
