Stop spreading misinformation. Even if you're a non-techie you can add non-Steam games to Steam's launcher (my extremely tech illiterate friend just did this) and they'll run with Proton.

It comes down to a game by game basis, and it's still extremely rare (outside of recent 2025/2026 anticheat AAA title stuff) that any game would have a Linux specific/impacting patch.
