GE-Proton vs Q4Wine

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.

Q4Wine is a free Qt graphical interface for Wine that helps manage Wine prefixes and installed applications. It can work with different Wine versions at the same time, and lets users create, delete, back up, restore, and otherwise manage prefixes. The Programs tab can create icons for user-configured applications and export them as .desktop files; the Process tab manages running Wine processes. The Setup tab can use the Winetricks script plugin. Q4Wine can record output from Wine applications, but logging is off by default, and saved log history can reduce performance. The Wine AppDB browser is obsolete and disabled by default in the v1.4.0 release notes. The maker lists Linux, FreeBSD, and OS X as supported systems, while stable Mac OS X packages are not yet available; users can build from source. Stable releases are linked from GitHub, and distribution packages are generally supported by community members and distribution maintainers. Q4Wine is published under GNU GPL V3 with no warranty, and its author says they do not provide support for related Wine, installation, Linux, or Windows issues.
