Using Gamescope / a GNOME tip if you use fractional display scaling

Gamescope can be used to run Resonite at full resolution on say a 3840x2160 display, instead of 2560x1440 as mandated by 150% fractional scaling.
This 2560x1440 resolution limit on 4K displays without Gamescope is due to GNOME’s lack of support for native scaling through XWayland.

For Ubuntu 24.10, follow my instructions on how to compile and install Gamescope.

Through Steam’s library, here’s an example of the launch options you could give Resonite: gamescope -e -f -W 3840 -H 2160 -r 120 — %command% -LoadAssembly Libraries/ResoniteModLoader.dll -DoNotAutoLoadHome -SkipIntroTutorial
