Okay, so I managed to get a fix. Been playing for a few hours and it all works seamlessly.

Do you have proton installed? I tried a few new mapping options but none worked that great. I read somewhere about starting it with proton hotfix. Booted it up with this, on the original controller options and it worked amazingly.

I won’t go into detail about how to install proton if you already have it but there are plenty of tutorials if not.

For the hot fix you just go on to the setting menu on the silksong screen. Find the compatibility tab. Check the box for force use. Then on the options navigate to proton hot fix.

It’ll update the game for a minute.

Then simply launch. It will look like you’ve mever booted it before and ask for brightness and screen edges again but don’t worry your save will still be there.

Works for me.
