Full-time Linux user & hobby dev here. I’ll say it. Good proton support is better than a bad native edition.

It’s an annoyingly frequent occurrence: I often need to run a windows version of a game to fix issues or get better performance over a neglected native release. They’re often started with good intentions or for good PR, but quickly realize the miniscule install base can’t justify continued investment, especially with the incredibly high fragmentation / variability of Linux environments. Supporting proton is often a much lower bar to pass, and usually gives better results anyways when you have a limited budget for Linux.
