I got a v62 update on both my QPro and meta link PC app today. Still none for my Q3. I'm not on PTC with either headset or the PC app btw.
QPro version is v62.0.0.248.343
Meta Link PC version is v62.0.0.235.345
So far my QPro seems to be working fine, standalone and PCVR with Air Link. My Pro controllers seem to stay connected a bit better when going back and forth from standalone to PCVR. I haven't tried any v62 enhancements yet because they don't really interest me. I mainly use my QPro for PCVR with Air Link or Link. I may try out a few of these later with my Q3 since I'm mainly using it for standalone VR/MR.
My Q3 hasn't updated to v62 yet so I don't see a PCVR 120Hz option yet. I did notice that the PC app device graphics settings res slider looks like it has a small extension tacked on to the far right but since my Q3 doesn't have v62 yet this extension is not selectable. Looks like v62 may not only unlock PCVR 120Hz, but also provide a small encoding increase to take advantage of the Q3's higher resolution. It'll be interesting to see if this makes any significant difference in clarity, hopefully not at the cost of too much loss in performance.
I'll report back with updates once my Q3 receives v62.
