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
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.
Disabling composition will dramatically improve input lag and "smoothness". Here is how to do it:
- If you use Gnome (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.
- If you use KDE:
- For Lutris: Right click the game ->
Configure
->System options
->Disable desktop effects
. - For Steam, Heroic or others: Manually disable composition with
shift
+alt
+f12
before launching the game. The same combination re-enables it. - You can use Autocomposer
- For Lutris: Right click the game ->
- If you use Cinnamon: Go to
settings
->general
->disable compositing for full-screen window
