After my issue, that after the download of PTC v25 my Oculus-app doesnt start anymore (seems like the OVRServer is crashing in loop) i have cleaned my Oculus-Installation, deleted anything related in %appdata% and Registry (Windows 10) and reinstalled the Oculus-App. Now - when i activate PTC in the settings, the Download of PTC v25 does not start. Ive waited several days (since last saturday) and nothing happens. I am on a clean install v23 and the download of ptc v25 is queued and nothing happens. Any hint, how i can solve this problem ?

No change since 1 week: The PTC-Download wont start.

I finally solved my problems - even though im a little bit pi**ed off regarding the support of Oculus - i want to share my solution for those of you, who also are searching the forums for hours and hours to find a possible hint to fix soI mething, that never should be broken.

On my system (specs are very unimportant) everything worked fine till autoupdate from PTC v24 to PTC v25. I am using the PTC because of FlightSimulator2020. After the autoupdate i wasn´t able to start the oculus app anymore, because the OVRService (exe within /support/runtime/) crashed and restarted in an endless loop. I wasn´t able to fix that and didnt found any reason or solution for this issue - so i decided to reinstall the oculus app.

After a new install of the oculus app (installed version stable v23) - everything worked fine. But to use my rift in FS2020 i have to use the PTC - so i activated it again. The new problem was now after the fresh reinstall of the Oculus app- the download of PTC v25 didn´t started (see posts above). Reason for that : my origin software-directory for Oculus Games and Apps was outside of c:/program files/Oculus/software. All my games and game-related-stuff is on a separated ssd-drive D:. Because if u deinstall/delete the oculus app, the registry-entries are not deleted - every new installation of the oculus-app set the data-directory back to Drive d: (in my case d:/oculus/) and the oculus wasn´t able to access or get write permissions on c:/program files/software this is reproducible. Just create a data directory anywhere else and make it standard - after that reinstall the oculus-app and you are f**cked up.

(note for myself .. could this be a solution, if i dont want the app to be updated ?!?!?)

My solution for this was to install the oculus-app also to drive d:. For that you have to run the OculusSetup.exe from commandline and give it the extension /drive. Then your oculus app will be installed outside of restricted c:/program files/

After that the download of PTC v25 started immediately but my origin problem was back again - the oculus-app crashed in loop. So beginning from the start - no answers from the community or oculus-support so far.

Another thread from a french rift user gave me the hint. He had the problem, that he had a windows-username with non-english characters. So do i - im using a windows-username with ö (im german) and on top of that - my username is my prename and lastname seperated by a blank. And to be clear - that was and is never a problem for me including stable v23 and ptc v24. So they changed this in PTC v25.

I made a new windows-user without any non-english characters and/or a blank, logged in and everything worked fine.
The oculus-app ptc v25 is working, no crashes .. everything as expected.

So far my cents .. have a nice weekend.

PTC v.25 USB-Link broken.
speed test in v.23 2.2Gbps-2.4Gbps
speed test in v.25 1.4Gbps-1.8Gbps .
And sound in headphones stutters in PTC v.25
What a hell ??? :#

Do you see any difference in quality/latency etc. with the reduced speed? 

for me:
speed test in v23 was 2.8 Gbps consistently
speed test in v25 is 2.4 Gbps consistently

For me it was 2.2Gbps v23 and now 1.9Gbps v25.
I didn't do any elaborate testing but I recently upgraded my system so I had a range of Gbps values. My old motherboard would only do ~1.1-1.2 Gbps and the fastest port on my new MB does 2.4 Gbps. From what I've seen, Link quality and performance has not really been affected by this at all. I suspect all you need is "enough" bandwidth and once you reach that threshold any headroom doesn't offer any benefits.
-->I would really really like to hear something from the DEVs on this, but I don't think bandwidth is the limiting factor when it comes to Link. But what else could be the bottleneck? Encode/Decode times?

Yes. in v.25 I have stutters and decrease fps with 500 mbps.But all fine in v.23

Did you really delete it? Where was it? Is it even possible to have backups of previous installs?
I've never deleted a previous install since 2017 (and there's been lots), so are they all still somewhere on my drives? I don't think so.
I don't think anyone has a backup of a previous PTC version. (but I could be wrong, it happened once before)
