BeamMP On Steamdeck?

Sure thing! Check out these links:

EDIT: beamMP has gone native! works ONLY on non-steamOS distro’s (steamOS is on read-only FS, therefore compiling native beamMP is NOT recommended on steamOS) and ONLY in X11 desktop mode (e.g. KDE). beamNG was NOT coded for wayland. my recommendation: cachyOS handheld edition, bazzite or endeavourOS.

below are links to PROTON beamMP and NATIVE (vulkan) beamNG
or
NATIVE beamMP and PROTON (directx) beamNG
and vice versa

Take care <3
