Hey Everyone,

The Public Test Channel (PTC) for Quest v78 started to roll out today for Meta Quest 2, Meta Quest Pro, Meta Quest 3 and Meta Quest 3S.

If you're seeing an issue or bug after updating to PTC v78:

1) For issues: Go to our Get Help board and search for any existing thread on the issue, if you don't find one, make a new thread. Please add the tag "PTC v78" to the thread and in the title. This way everyone can look for just PTC v78 issues too.

2) For bugs: If you come across a bug, please post each one you spot in its own thread, to keep track of individual issues separately. Please make sure to also send in bug reports along with posting on the forums if you notice anything going wrong.

Share your impressions in the comments below and let us know if you see any issues.

We know it's tough when you run into a problem on a PTC build and want to thank you all again for testing out PTC and sharing your feedback! This feedback is extremely helpful to our engineering teams. We appreciate your interest and persistence in testing out the core functionality of software as we develop!

    I like that you can say whatever you want in these threads because it's obvious from the state of the regular updates that nobody from Meta actually reads them.

    They don't care about our feedback.
    They don't care about our opinions.
    They don't care about our problems.
    They have no purpose in communicating with us.

    bowow 

    quest pro wifi throghput has been restored massivly in the last update in v78.

    it trippeld (thank you for that meta) BUT for me it looks like it is NOT COMPLETLY restored yet!

    i had measured quest 3 and quest pro on same router in the past before the quest pro performance was cut to ~400mbit/s AND both, Quest 3 and Quest Pro performed nearly same in terms of throughput.

    i am using a wifi 7 router that supports 6ghz and 320mhz channelbandwidth at max. (Quest Pro and Quest 3 both use Wifi 6e and 160mhz channelbandwidth, i have also checked if both connect with 2401mbit/s and they do.) 

    i still measure difference around 400mbit/s as can be seen in the image (left is quest pro, right is quest 3)

    so i am very thankful that wifi throughput performance has partially restore on quest pro BUT i think there is still something to restore left, so that the old value come back completly!

    offbeatkid and antoher thing.

    the navigator ui is interesting BUT it eats so much performance on quest pro with its xr2+ gen 1 that when it is open and the user scrolls though his app-icons the user gets a choppy experience because framerate tanks below 90 fps in a standard home environment like oculus home (that does not eat that much performance)

    maybe meta can improve performance of navigator or the lazy solution should be to drop refreshrate to 72hz in the homeenvironment as the standard on quest pro (probably on quest 2 aswell, but did not test on quest 2).



    it also drops below 90 frames/s while i am not recording ...

    you propably need some of these optimization people like carmack back that can make things run on a better toaster with their optimizationtricks because they had to do these things on old pc hardware all the time to get something running  😁

    That's not good considering this new UI is being designed for AR specs which are a lot smaller and less powerful than a Q3 ? Unless meta has designed a chip that is a fraction of the size of the latest XR2 chips and twice as powerful and output nearly no heat when running full tilt..!! (Yes a tad sarcastic here!) 

    Personally I think they should scrap that UI and go back to the old one..! A newer UI is meant to make operating a device faster and smoother with less interactions to get stuff done and this UI is the complete opposite ! Example, 1 click to get to settings in old. now takes 2 clicks and then multi clicks to get back! and currently your jumping between 2 UI's one for just to view your Apps and the old one for everything else!!?? At the very lease give us the option to switch it OFF!

    Moriarti4  the 'puck' for the new AR specs is the size of a large travel suitcase with wheels and an extendible handle, which will need to go in the cargo hold if you ever travel by air.

    I'm not sure what to say anymore. I bought the headset for fitness, which is a really important part of my life right now. All I was doing was playing modded Beat Saber and tracking my calories with the Move app. I didn’t want anything else.

    But now, first you removed the Move app, then Beat Saber stopped working, and today, after I reset the headset and lost everything, I can't install anything anymore. It's just a useless brick now.

    I've been contacting your support for months, and you keep ignoring me when I ask for a refund for the headset and accessories, even though it's still under warranty.

    Before V78

    After V78

    After the V78 update, the charging speed has slowed down. Now, when I connect a power bank and play games, the battery does not charge and slowly drains. 

    The photos above were taken using the Quest Pro's bundled charger (45W).

    Please fix this issue.

    DeathTree The information in your photos says something else. On version 78, your helmet charges with more power.
