Crosswire vs GE-Proton

Crosswire runs Windows games and apps on macOS, letting users install a Windows .exe and open it from a searchable library. Each installation has an isolated space, keeping apps separate. During installation, Crosswire detects common runtimes such as Visual C++ and .NET and offers to install them. For recognized games, it applies known-good settings automatically. The app can check for and update its Windows compatibility layer; automatic releases are available on version 1.1.1 or later. Crosswire is free and open source under GPL-3.0, with source published on GitHub. It requires an Apple Silicon Mac running macOS 14.6 or later, plus about 1 GB of free disk space for the base install. It is not Apple-notarized yet, so macOS requires users to confirm opening it in Privacy & Security. Compatibility varies by app version and macOS release. Microsoft 365 is unsupported, while League of Legends and Valorant are blocked by Vanguard.

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.
