v25 PTC PC Software Release Notes

Oculus Link

  • You can now set your refresh rate to 80hz and 90hz when using Link with a USB-2 cable.
    • Keep in mind, that even with some of the newest and most powerful GPUs, maxing out values for the render resolution slider with a 90 Hz refresh rate may result in dropped or missing frames.
  • Fixed an issue causing Link to show a black screen after exit.
  • Reduced incidence of “Oculus Link is not working” errors that were happening on shut down. 

(Quick note version numbering: v25 will be the next live release for everyone, as v24 will stay as an internal stability build only)

    Tbh, Oculus should cut USB2 support. VR ready PC, but no USB3? lol 



    i do see your point, however some people with usb3 have problems when using less than perfect cables (and sometimes even the offiical one) where a usb3 connection will occasionally drop to usb2...... at the moment when this happens it does still work at least,  if they did what you suggest players would not be able to play at all.


    Fiat Coupe, gone. 350Z gone. Dirty nappies, no sleep & practical transport incoming. Thank goodness for VR :)

    The recommended maximum cable length for USB3 is 3 meters and the signal will quickly degrade once you go past that because of signal timing and high frequencies needed for USB3 bandwidth.
    For USB2 the recommended length is 5 meter, and the signal will degrade less on subpar cable because the frequency is lower. And the USB2 High Speed bandwidth (480Mbit/sec) should be enough even for VR streaming.
    So in short, nothing is free. Faster usually means shorter cables and less resistance against interference and signal degradation.

    You should not have these problems.  If you do, contact Oculus Support and start a ticket.  Also, why are you posting on a PTC thread?

    I have the same issues. Link stopped working completely right after v25. Can't get it to work and have the official Oculus cable.
    Also seeing reduced bandwidth when doing a speed test.

    On v25 i started seeing an issue on Quest 2 Link playing dirt rally 2.0 (steam) where the bottom half of my screen would have like a white-distorted overlay on it shortly after entering VR mode for a race.  Exiting quest link resolves the issue in the headset... appears to be a quest link related issue.

    Reverted back to v23 and couldn't reproduce the issue.

    Specs:
    Win10 latest
    RTX 3090 - latest drivers
    i9 10900k



    Good description. I've encountered this in DCS. When I have been able to connect to DCS without the recent regular 'link' disconnections I've encountered since the v25 update (not had this occur once with v23), at times (not all the time) I have experienced what you have described. When I have encountered this strange white/grey distorted overlay (bottom half of each lenses) it can happen shortly after connecting into DCS, or after a period of time.

    Would you mind posting how you reverted back to v23?

    Guys I think I have done this downgrade back to 24. I get much better cable bandwidth and no home screen. But the version still says 25 is that right?

    I think there isn't v24.
