Please address the 72hz bug when using Link. I sent a feedback form with log many weeks back informing the Oculus PC devs of the issue with v27.
edit - I should clarify I'm still on v26, but ppl have reported the v27 rollout still includes the 72hz bug.
My Quest 1 updated to v27 a few days ago and my PC updated to v27 today. Absolutely no problems with my Rift cv1, Quest 1 w/official Link cable, Q1 wireless with Virtual Desktop, or Q1 standalone. My Q1 is also v27. Only thing I noticed was that my usb3 (MB 3.2gen2 port) connection speed test now shows 1.2Gbps instead of 1.7Gbps with v26. This does not seem to make any difference to me, even with high demand flight sims. Also, I noticed that my link graphics settings for my Q1 are capped at 1.0x. I have a rtx3090 so I was previously using 1.3x (remember these will be different for the Q2). Also capped at 72Hz as expected with my Q1.
While I did not see any differences with either my Rift cv1 or Q1 wireless w/VD, I have never seen Link look so good and run so smoothly before. Still a few compression artifacts, but not really all that noticeable. If Link keeps on improving maybe I'll be able to finally retire my good old Rift cv1, lol!
I hope others are as 'lucky' with these v27 updates.
Since you own a Quest 1, you are certainly unaffected by the 72hz bug which prevents the Quest 2 from running at 80 or 90hz due to the V27 headset firmware.
I noticed though that your Quest 1 is limited to a render resolution of 1.0x when before you can set this to 1.3x. This is probably due to the V27 headset firmware. Us Quest 2 owners are also limited to a render resolution of 1.5x when we can set this before to 1.7x on pre-V27 headset firmware.
