Bottles is just a GUI to help you set up wine environments without having to deal with wine directly.

For troubleshooting just the lutris forums and wine bugtracker. I mostly play steam games so protondb is the best source of troubleshooting tips.

For those of us who didn’t know, CachyOS is and Arch-based distor with performance focus and some ease of use tools.

this blog explains some difference to other Arch-based distros

Da Vinci Resolve has native Linux builds though and should work. And does on Ubuntu based, Rocky Linux, arch and NixOS. I’m not sure about Nobora (Fedora based).

Though it’s hard to know what went wrong with vague descriptions like “everything was crashing”…

Tip: Add your non-steam games to steam to launch launch them with Proton. thats probably the easiest way.

Otherwise there’s Bottles and Lutris (and maybe HeroicLauncher)
