That's great! More companies should support OSS devs, as they are making a big profit from their labour

Yeah I love this. Christmas came early for me when I heard this news. In my Fedora 36 gaming box with proprietary Nvidia drivers and games from steam every game just works. I don’t even think about it. They have gotten the whole proton stuff very seamlessly integrated. It’s beautiful.

I'm thinking of moving my gaming box from Windows to Linux, but last time I checked, things weren't as great on the hardware tuning side of things.

I'm running a Radeon 6800 XT undervolted at stock clocks and 980 mV (+ custom fan curve) and I don't think I could keep it cool without the undervolt. How achievable is that in Linux these days?

I'm also thinking of getting a steering wheel and getting back into race simming, are these kinds of peripherals well supported, or is it a game of chance?

https://gitlab.com/corectrl/corectrl should do it. I've got a 6900XT and undervolting works fine. So does core clock and fan curve, but memory clock has issues: https://gitlab.com/corectrl/corectrl/-/issues/139 (edit: that issue is closed, so maybe it works now).

As far as peripherals, sometimes it works better than windows and sometimes not great. I'd look up the specific wheel you plan to buy and see if it's supported or someone has built something to support it. For example, you've got piper (https://github.com/libratbag/piper) for Logitech devices.
