I don't have a lot of space where my desk is but wanted a combo space combat and racing rig that was fully rigid except for the seat.
The chair sits in a wheel trough with some 3d printed wheel chalks that fit the wheels exactly so it doesn't really move much at all when braking.
Everything is running on Linux using a lot of SDL and input device spoofing hacks to get it all recognized correctly in games. I mostly play DirtRally2.0, BeamNG, AMS2, and Overload. Trying to get into Elite Dangerous but it's not really my type of game. Maybe it will be some day though. Also play a little RBR but not all that much.
List of gear:
T300rs with a R383 Mod wheel - tmff2 driver. I designed a "quick" release ring so it's not a pain to take the wheel off for flight.
Heusinkveld Ultimate+ pedals - protopedal or xboxdrv depending on the game
TH8A shifter - heavily modified to fit in the small space I had and with a 3d printed short throw plate that I designed. It's not ideal, but works for occasional use.
Some ebay handbrake - I use xboxdrv for this sometimes if necessary but most games can find it. I also modified it to be mounted under the plate for a bit more space on top.
Gladiator NXT EVO Omni Throttle (Left and Right hand models) - These are a pain in most games. I use a winehid hack where I adjust the registry values HKEY_LOCAL_MACHINE System CurrentControlSet Enum WINEBUS VID_231D&PID_{200,201} {Service, CompatibleIds} from xinput to winehid. This works but depends on the bus the device is currently connected to. Looking for a better SDL env var alternative but haven't got it working yet.
Acer Nitro 37.5" QHD+ 3840 x 1600 curved display
NextLevelRacing "Wheel Stand 2.0" - I made some steel parts for it on the mill to increase rigidity, 3d printed spacers for the adjustable arms to tighten them up a bit since the stock ones are a bit sloppy, and made some extra plates for mounting the sticks and other stuff out of 10mm aluminum plate.
VKB UCM-S drop mount brackets for the sticks. I modified these as well to fit under the aluminum plates. The left one is hinged so that it can be folded upwards to get in and out of the chair when the chair wheels are fixed in place.
annnd... yes I know the shifter and handbrake are reversed... I like it that way.
Ah, yeah the Nacon WRC games are weird. I could never get them to work either but just with device detection in general, not only my wheel. Also people tend to say they weren't amazing in terms of FFB feel and gameplay either so I stuck with the more popular titles. You're totally right and I had completely forgotten that those games are just non-functional at the moment.
I don't use lutris for anything, I run umu directly with proton-ge for RBR and a few other non-steam games and it's been great. Upgrades are as easy as just launching explorer in the prefix and double clicking the RSF installer, and since 10-22 I think you don't even need the dll overrides since they are included in recent proton-ge. My opinions of the game and RSF are not as amazing though so I admittedly don't play it much. I used to a lot but found interacting with the community to be pretty taxing at best, and not good as a Linux player. All the wine/proton development work in the world can't improve a community that is borderline hostile towards a subset of players.
JacKeTUs has a fork of proton-ge which helps with device detection stability which is the issue with AMS2. They are working on upstreaming that work I believe, but I'm unsure what the status is. From what I've heard soon devices constantly unbinding in many games will be fixed very soon across the board in wine. Assuming there are no holdups with that work that I'm unaware of. For now I do as you said and rebind my wheel axes every time. It does seem to remember buttons and other controllers though, just not the steering axis.
