What it is

GE-Proton is a free, open-source custom build of Proton, a Steam Play compatibility tool based on Wine and additional components. Its base follows the most recent bleeding-edge Proton Experimental Wine described by the project. The protonfixes system applies per-game adjustments such as winetricks changes, environment variables, Easy Anti-Cheat workarounds and overrides. The build adds Media Foundation patches for video playback, raw-input mouse support, AMD FSR patches enabled with WINE_FULLSCREEN_FSR=1, and NVIDIA CUDA support for PhysX and NVAPI. NTSync is enabled when supported; the README specifies kernel 6.14 or newer with CONFIG_NTSYNC enabled. Installation instructions cover native Steam and Steam Flatpak, with release downloads provided. Heroic enables umu by default, and Lutris uses umu when GE-Proton Latest is selected. Non-Steam games outside Steam are supported only through umu-launcher. Linux installation requires suitable Vulkan drivers and packages.
