It’s just that games are easier to run on wine because they touch a comparatively small portion of the Windows API. Windowing, controller input, file system, networking, audio and directx covers the overwhelming majority of Windows API endpoints that need to be translated by wine. Their interaction with these APIs is relatively simple, open a window, read a few files, open a udp socket. Directx is hard, but the tools have gotten scary good lately (dxvk, vkd3d-proton). Compared to a complex tool like Photoshop which will be touching many more system APIs that need to behave correctly (file locking, codecs, COM). Arguably a Windows PE executable using Vulkan and run in Proton is a better way to ship a game to run on Linux than building a native Linux executable. It’s actually more portable because the Windows API and environment is more stable and consistent than some arbitrary Linux user space. No glibc versioning BS or dynamic linker path BS or any other number of strange things users can do. Just stable Win32. Valve actually recommends this over a native Linux build currently.
