Yes 1.2 was working for me with Vorpx 0.9, whilst 1.3 was still on PTU, although 1.3 didn’t work at all with 0.9, causing a crash at startup. Then 1.3 published to live and of course it still doesn’t work, but I don’t have the option to play 1.2 (with Vorpx 0.9 or without) anymore either.
Of note however, opentrack have just updated so it works with Oculus 0.8 runtime, so we have headtracking back, once the 1.3 crash on startup problem is overcome.
