Hi Ralf, first of all, you are making a really great job with Vorpx, now with the last update that Vorpx support extended mode for generic HMD, now to the point ; I like to play with Pimax 4K in extended mode, because I get better resolution (2K) than Steam Vr but I had not headtracking at all, Is there any solutions or cofig that I am missing out ?? Thanks and keep the good job.
The generic HMD mode is meant for people who want to use vorpX for pbone based VR with an additional software for tracking/streaming to the phone. For your Pimax please use Steam VR.
