Framedrops in games using Ubuntu and Gnome

I experienced frame drops especially in AAA shooter games under Linux even through I have a pretty solid hardware setup.

So I ran the benchmarks of Borderlands 3 and Far Cry 5 with Windows and with Linux. The average values were pretty much the same. However the framedrops (short stops in fluid animation) were noticable under Linux but not under Windows.

I read somewhere, Gnome plays a role in this. So I installed a slimmer window manager and ran the benchmarks again.

With the slimmer window managaer (I used i3wm, maybe even XFCE is slim enough already - there are a lot of options) the games ran without framedrops stutter-free in the higher graphical settings.

An additional performance boost can be achieved when deactivationg anti aliasing in the game settings.
