How deep did you look into it? Don't be misled by maybe your manufacturer not supporting Linux directly. As an example https://github.com/berarma/oversteer helped me to set up my wheel better than any rubbish windows OEM software could have.

There are apparently are some semi-experimental FFB drivers out there for a few wheels... but yeah, most hardware has a zero percent chance of working, because it's a niche of a niche. And then if you're doing online racing, they all(?) have anti-cheat stuff that won't work for you anyway.

If games transition to SteamOS/Linux in general, I think this niche is going to be one of the slower ones to move, but never say never.

Have you actually tried it? Dual sticks (which is not quite as niche as a racing cockpit but still somewhat) via Wine just worked for me with zero effort - actually less than Windows which had joystick ID horrors.

My only limitation to ditch Windows for games is my nvidia card. I wonder if their drivers will become better before I go for an upgrade. I do have a Steam Deck for lower requirement games.

There are lots of niches like that. The other big one is competitive games with invasive anti cheat.
