Yup, similar boat but with planes instead of cars. Most inputs Linux can support on a single usb device is 86 or so, my throttle alone has well over 150 buttons on it. Add in all the stuff for my sim cockpit (probably around 1000 buttons), my haptic feedback chair, and then VR… as much as I’d like to use Linux, I don’t think it’d be possible for the foreseeable future for me to switch.
This actually kinda reminds me of PointCtrl used in VR mouse control for flight sims. It may look uncomfortable but if it works similar to it it’s actually incredibly intuitive to use
