Hello @napastnikiek, we're using one issue report per unofficially supported game title, so I've gone ahead and transferred this issue report to https://github.com/ValveSoftware/Proton/issues/1237#issuecomment-3476356528.
proton experimentalx1 2025-11
BeamNG.drive includes a native Linux version located in the "binLinux" folder.
However, Steam currently marks the game as Windows-only and launches it through Proton by default,
even though the native Linux version runs perfectly without any issues.
This appears to be a manifest or packaging issue where the Steam client does not detect
Steam should recognize and launch the native Linux version automatically, without Proton.
Game: https://store.steampowered.com/app/284160/BeamNGdrive/
System: Debian 13
Steam client: Latest stable build (as of November 2025)
GPU: NVIDIA GeForce GTX 1050 Ti
Driver: Latest proprietary NVIDIA driver (from Debian non-free repository)
Proton version (used automatically): Proton Experimental
The native Linux version of BeamNG.drive runs correctly when launched manually from its Linux executable.
Steam should detect and launch this native build instead of forcing Proton.
