PC Software Build 28.0 Release Notes

These features and enhancements will become available starting the week of April 19th, 2021.

 

Oculus Air Link

  • Oculus Air Link allows you to discover and pair your Oculus Quest 2 headset to your Oculus-ready PC over a secure Wi-Fi network.
  • You can opt in to this experimental feature from the Experimental Features section of Settings. Follow the instructions on our support site to set up Oculus Air Link.
  • Note: Air Link is part of v28 but it requires that both your headset and PC be running v28 software. That means we’ll be unlocking Air Link once both Quest and PC v28 releases are rolled out, which will happen soon - but you won’t see Air Link just yet, so stay tuned.

Bug Fixes

  • Fixed an issue with the USB Cable Benchmarking tool for Oculus Link which would result in lower than expected speeds to be reported.

      I got PTC 29.0.0.48.528 now. Any v28 problems aren't solved. White stripe problem, screen edge problem, encode resolution bug, distortion curvature bug... Link is still unuseable!!! 😡

      EDIT: Got 29.0.0.54.528. No difference.

        Edit - I fixed the issue by updating my nvidia drivers and disabling the Link settings in Oculus Tray Tools (OTT). Thanks to TomC for the troubleshooting help.

         

        I finally for around to trying v28, PTC v29 on wired Link (busy and playing Quest titles).  I too experience the same horizontal visual artifact in the lower 1/4 of the visual field. Below this line, there's also a different tint to the image.  The lower visual field has a very noticeable difference to the rest of the image.  I have never experienced this artifact when using previous versions of the Oculus PC app.

         

        I recently purchased some PCVR games to play via Link, so discovering this bug is pretty irritating. I hope it is addressed soon.

         

        I also submitted an Oculus feedback form via the PC app.

        Using the Quest 2, RTX 3080.

         

        Thanks

        ShocksVR  v28 (you should not try v29ptc yet imho) all working well with my Q2 with either my official link cable and Air Link.  With Air Link there seems to be a few changes that may effect wired Link as well.  Try going into ODT and make sure everything is default, esp. encoding and bitrate (both need to be = 0).  Also go into you Oculus Desktop app device/q2 Graphics quality and leave the slider on default.  With your strong gpu you should be able to select 90Hz refresh (then just accept the default rendering.

         

        If you are using OTT go into the Link panel and disable OTT setting.  After saving and restarting you can play around with global SS and ASW, and finetune these later using game profiles. 

         

        Also make sure your nvidia drivers and win10 are up to date.  Sorry, all I can think of.  With so many systems out there it's pretty hard to second guess exactly what is causing your problems.

         

        If you are still having problems I think you are best to contact Oculus Support and attach your log files.  This may give them a bit more info than the app feedback form.  Good luck mate and cheers.

          FYI Build 28 breaks the Rift S...persistent random black screens and driver crashes.  I manually rolled back to v25 (most recent version I had available to test with) and blocked the Oculus app from auto updating in firewall list and it fixed the issue, no more black screens after testing for 8 hours...as soon as I unblock in Firewall and it auto updates to v28 again (or the PTC update) the black screen/driver crash issue returns.  Someone in QC needs to get yelled at.

            PTC v30 notes ?

             

            I see the General tab now shows OpenXR status.  The Oculus Debug Tool also has some extra features - dual NVENC ?

             

            thanks !

            Oh, I got 30.0.0.18.502 now.

             

            White stripe problem is solved! Wait... not solved!!! 😂

            Encode resolution bug is still there. Worthless update... 🤣

            The Link problem could be on your end. 

            Go back and read my previous replies in this thread.  I had the visual line artifact in the lower 1/4 of my visual field, I was able to fix it by resetting my Link settings.

             

            And what's the Encode Resolution bug ?

            Got the Desktop-App v30 in the release-channel yesterday... no words on changes / release-notes.
            Also not on the official site: Oculus - Release-Notes - latest ist v29 back to may.

             

            Works with firmware v29 on Quest 2... Air Link has to be activated in beta-section as before.

             

            One new option (also in beta-section of the app) : OpenXR - runtime.
            (wich should reset OpenXR back to Oculus if that changed in multi HMD environments)

            I noticed "dynamic bitrate offset" was added in ODT. I don't know other changes. 😛

            I don't understand why they don't post release notes.

            Got an update of the Oculus-App from 30.0.0.36.502 to 31.1.0.67.507.

            As "always" no word on what's changed... nor a communty thread für the freshly released firmware v31.

            Oculus, what's up to you?
            No community work anymore?

            Recent changes to airplay and dynamic bitrate seems to have bricked some Rift S's into a loading loop. A loop that can be recreated by setting the bitrate to something unusable via oculus debug tool.

            Simply turning on Airplay ended my three dot loading loop and brought me to a failed dash with passthrough.

            I informed support of this issue with the recent updates and was told to not raise unneeded tickets.

            I don't want to say that this bitrate change was done to purposefully destroy some Rift S's that had camera sensors that were known to be out of warranty. I however will say that they sure don't want any help fixing what they broke.

            Why has there not been ANY posted updates on Oculus PC software.

            PTC is on v35 and NO patch notes.

            I've got a sinking feeling they are trying to kill pcvr.
