Quest Pro Help

I have crashes with Rift-S and running MT with Turbo Mode On when taking headset off (ST is fine). Turbo Mode set to OFF solves the problem.
Bug has been around for quite a while, nothing to do with latest updates (either DCS or Oculus).

I wonder why it has only just become a problem for me? I had occasional issues but not as frequently as it has been for the last few weeks.

Could an update have reset the 'sleep timer' type setting that was introduced back in an earlier headset update? Pretty sure q-pro received the option. I believe turbo mode makes the game/gpu communication ignore some kind of frame sync info, which cures the DCS jitters when GPU scheduling is enabled, but will cause DCS to crash if headset sleeps/wakes 

The last q3 headset update changed my headset frequency back to 70hz. It's never happened in earlier updates - so I guess anything is possible after an update

OK. I have resolved my regular crash issue. Clearing out the metashaders2 and fxo folder appears to have solved that one.

As part of my troubleshooting endeavour, I stripped DCS back to vanilla install with all the mods, etc, removed and then I started putting them back one by one. My observations:

1. Vanilla DCS and Quest headset removal works as expected.
2. OpenXR Toolkit with Turbo on, remove headset - DCS hangs.
3. OpenXR Toolkit with turbo on (as we know it smooths the sim out a lot), Quad View Foveated Rendering Layer active (but not advertised for DCS - so running but not doing any QVFR), remove headset does not hang DCS.

So, as I said previously, the workaround to stop Quest headset removal with OpenXR Toolkit hanging DCS is to install QVFR. And if, like me, you don't want QVFR to actually do QVFR because it increases frame times and causes stutter in densely populated areas for high-specced systems, unadvertise it for DCS in the config file.

Thus, it's unfair to blame ED for the hang, as it works ok without the OpenXR Toolkit running. However, I'm not too keen on running an extra layer to fix another issue. I've seen mbucchia's code change in QVFR to solve the headset removal hang. I might look at the OpenXR Toolkit and see if I can migrate the change across for those who don't want to run QVFR or VDXR.

Is that helpful, or am I still being a smart arse???? Lol.

I've turned off "turbo mode" in QVFR and OXRTK and after 4 hours I have had no issues. 

[slughead]

You can leave it on in QVFR if you are using the QVFR. mbucchia fixed the problem in that OpenXR layer. But if you don't want to use QVFR but want turbo on (as it does have a decent benefit), turn it on in OPXR Toolkit and unadvertise QVFR for DCS in the QVFR settings file: no more hang, but turbo boost on — best of both worlds. Just don't enable it in both.

Thanks. I'll try that. I don't really use OXRTK anyway. Just for contrast/saturation adjustments. 

[slughead]

Yeah, me neither. I only use it for turbo mode.

[Qcumber]

I tried enabling turbo in QVFR and crashed when i took my headset off. Disabling it in both QVFR and OXRTK seems to work. 

[slughead]

I don't use Turbo Mode in QVFR as I have effectively disabled QVFR. So I only use Turbo Mode from OpenXR Toolkit.

I thought I'd give Virtual Desktop another go. It's a stutter fest, and frame rates are unstable. How are people saying this is great / better than Oculus Link? Is there a tuning guide somewhere? For the life of me, I can't find anything official. I'm running a 13900 and a 4090 with 64GB RAM.

I am finding it is the same since the v64/65 update. The frametimes are all over the place even when I have plenty of GPU and CPU overhead. I need to post some logs on their discord server. Oculus link is better, when it works (the last few weeks have been a challenge). I am hoping () that I have now solved all of my issues with link-cable. I really want VD to be the ultimate solution. I would love a cable version but I don't think it is doable. 

[slughead]

I couldn't see any chatter about it on their discord. Oculus Link works great for me. No more audio jitters since a few releases ago.

Hey @Qcumber, can you share the DCS and VD settings that you were using so that I can compare?

I'll post some screenshots later.

Don't worry. I've sorted it to a degree. I was using my machine as a hotspot. I switched to my router, which has improved it dramatically but still has some stutters and network delays. I think that can only be resolved with a dedicated gaming router. That's something I am not willing to fork out for to try out VD with DCS.

What do your latencies look like? 

I use a dedicated router which cost me about £40 in Amazon. 

[slughead]

The problem is the network frame times, mainly in the amber. All others are okay. Hence, it's a network issue.

[Qcumber]

Here are my settings in case they help. It does sound like a network issue.

 

[slughead]

Yeah, my networking is 17ms and upwards. I'd need a dedicated router. What router are you using?

This is the one I got. It was a bit cheaper when I bought it.
