If you use a DE with X11, then you probably have a compositor. The compositor does nice things like window shadow and effects. But it also reduces fps, adds input lag, and introduces stuttering. That's why you should disable it when running a game.
Disabling composition for your games
Disabling composition will dramatically improve input lag and "smoothness". Here is how to do it:
Gnome
This is the default DE on Pop!_OS.
You don't have to do anything. Gnome uses unredirection (the same thing Windows does), which is almost as good as disabling compositon. Disabling composition in Gnome is not possible.
KDE
- For Lutris:
- To disable it for a single game: Right click the game ->
Configure->System options->Disable desktop effects. - To disable it for all games: Click
...in the top right corner ->Preferences->Global options->Disable desktop effects
- To disable it for a single game: Right click the game ->
- For Steam, Heroic or others: Manually disable composition with
shift+alt+f12before launching the game. The same combination re-enables it. (TODO: It may be that Steam and Heroic automatically disable composition. But I don't know.) - You can use Autocomposer. This should make it unnecessary to do anything of the above.
- If you want to use a terminal command (for example for automation, launch options for Steam, etc):
- disable:
qdbus org.kde.KWin /Compositor suspend - enable:
qdbus org.kde.KWin /Compositor resume
- disable:
Cinnamon
This page needs work, for the following reason(s): I don't know whether the procedure for disabling composition in Cinnamon actually works. In case this does not work, you should not be using Cinnamon. If you want a DE that looks a bit like Windows, you should choose KDE Plasma instead. Please edit if you know more.
Go to settings -> general -> disable compositing for full-screen window
Xfce:
- Disable composition with
$ xfconf-query -c xfwm4 -p /general/use_compositing -s false[1] - Enable it again with
$ xfconf-query -c xfwm4 -p /general/use_compositing -s true - For Steam: You can automate disabling/enabling with the launch option:
xfconf-query -c xfwm4 -p /general/use_compositing -s false; %command%; xfconf-query -c xfwm4 -p /general/use_compositing -s true[2]
