[SOLVED] Bad performance in Xfce for games

I've been testing some native games on my Dell XPS 13 (1943, Intel HD 5500) , and I'm getting much better performance(more fps/no tearing) in Gnome(Xorg) than with Xfce on Xorg.

How is this possible, even with a lightweight DM like Xfce?

No, like I said in Xorg.
I'm not using Wayland since most games can't find other native resolutions. I'm also not able to use xrandr in Wayland, so I just run Gnome on X.

try to disable xfwm4 compositing and/or try openbox.

Re: [SOLVED] Bad performance in Xfce for games

If your WM doesn't do any compositing, and the game itself doesn't implement Vsync you will get tearing. On the other hand if a game does implement vsync, they can and do often, set a WM_Hint that the WM should disable compositing for this window, an option which something as full featured as GNOME is likely to hone and smaller WMs might not have implemented. That are two big reason I could think of why you see this.

Thnx! It was indeed just the xfwm4 compositing that was causing this choppy performance.

How can I do this in Xfce so I don't have to disable my compositing?

I don't think it has support for that directly. However even on GNOME compositing will be disabled here you just have to remember to do it yourself.
