Head tracking is a gamechanger for flying or driving games. I’ve used opentrack successfully with Star Citizen via lutris but have been struggling to get it working for steam games. LookPilot seems to work well and is fairly cheap but isn’t FOSS. I know there are loads of other alternatives so I’m wondering what have you found that works well?
You’d be surprised. Linux is where good hardware goes to live forever.
For example, the super weird “Sidewinder Strategic Commander” runs out of the box on Linux. A Microsoft device. That got its drivers deprecated after XP SP2, runs today on new kernels without doing anything
