It’s so cringe too scrolling down and seeing 5 posts at 0 with like 10+ comments all saying that the new update is being buggy is fine and not acknowledging things like the microSD card wiping bug, and conveniently omitting that Valve skipped the beta channel entirely
The only way for a lot of games is mods. Nexusmods/gamebanana would have any button input mods you would need, if they’ve been made
You can easily choose not to update for both OS’s, people clamoring to update either one would be dumb. I always wait 2 weeks minimum to update steamOS. There’s also such thing as LTSC Windows where you don’t get updates (versus LTSC IoT Enterprise, both easily installable)
If you pair a more official controller like an Xbox series/dualsense controller, the steam input enabling box re-appears. Then you can enable it for the game, and can then switch controllers
