I really wanted to like Mint cinnamon but it didn't like my dual screen+built in screen on my pc case.
It would try and smush the display for the pc case screen into the monitor displays pushing everything over and making mouse clicks widely inaccurate (the click was half a screens away from the actual cursor).
Only ever had that issue on Mint
I'm also currently running Linux Mint but want to start gaming on Linux as well. Given what you've said it would seem that I need to consider distro hopping.
I have a "working" knowledge of Arch, I say working loosely as I have a home server running Manjaro and kinda maybe know what I'm doing with it and I'm comfortable following guides etc.
Which of the 2 distros you mentioned would you recommend? CachyOS looks great on the surface but Bazzite definitely seems to cater to gaming and it's website heavily leans that way
