What GE-Proton is
GE-Proton is a custom build of Proton, the compatibility tool used with Steam Play, based on Wine and additional components. The project says its build uses the most recent bleeding-edge Proton Experimental Wine. Its protonfixes system can apply game-specific changes automatically, including winetricks changes, environment variables, Easy Anti-Cheat workarounds, and overrides. It also adds Media Foundation patches for video playback and raw input mouse support. Graphics features include AMD FSR patches, enabled with WINE_FULLSCREEN_FSR=1, and NVIDIA CUDA support for PhysX and NVAPI. NTSync is enabled when the kernel supports it; the README specifies kernel 6.14 or newer with CONFIG_NTSYNC enabled. Installation instructions cover native Steam and Steam Flatpak, and releases are available for download. Heroic enables umu by default for GE-Proton, while Lutris uses umu by default when GE-Proton Latest is selected. Outside Steam, non-Steam games are supported only through umu-launcher. GE-Proton is free and open source for Linux, but requires suitable Vulkan drivers and packages.
