TBH I currently only “own” the game because of a voucher tied to my RX6600. Else I would have waited, too.
Sidenote: in 1080p it runs at ~50-60FPS without FSR (native resolution). Plays on Windows and Linux about evenly well, albeit that I have seen some graphical glitches (on Linux, did not try to reproduce them on Windows 10) e.g. my follower doing a bl*ckface for no reason.
My music player suggestions for local playback on Linux. Please note that you could pick any of these no matter the desktop environment if you do not care about consistently in look and feel. In that case I suggest to go with Strawberry.
