VR crash toward the end of MP mission

[pixie]

Hi, 

 

It seems I 'm always crashing DCS (freeze) toward the end of my MP mission, it happens after 30 -  40mn or so. I haven't noticed any unusual temperature raise, or memory clogging. The only mod I have is VRperfkit 3.0. I'm running my own MP liberation missions on a separate dedicated PC on my local network.

Specs are :  ryzen7 5800x3D, 32GB, 3080ti, Quest2, no overclocking, and  SSD drive.

I'm playing VR on stable release, using Steam launcher with OculusVR api.

So far, I have : updated to the latest nvidia drivers, rebuilt fxo& metashaders, checked files integrity, run out of ideas !

Could someone make sense of my log and give me some advice ?

Hi. Your dcs.log doesn't show any crash nor freeze. Please attach the most recent ZIP file you can find in your "Logs" folder.

Thank you for your help Flappie

The last zip file is from june 2021, I believe it won't help you much since there was many hardware changes in between.

FWIW, here is my last log, again, there was the expected crash (DCS is not responding) tonight after playing almost 1 hour on liberation.

Since the crash always happens at some point or another, It could be memory related (or lack thereof). Since I have 32GB, the next usual suspect would be the pagefile. It's managed by windows, but I will be trying for a while a fixed 32go size on my DCS drive which is an NVME. I will let you know if it helps.

Do you have some more ideas ? Could this issue somehow be induced by Liberation ? Vrperfkit ?

Since I don't see anything wrong in your log file, I would have told you to try a 32 GB pagefile if you hadn't decided to do so already.

If this does not solve anything, please attach your Export.lua file (Saved Games/DCS.../Scripts/Export.lua).

Don't you ever sleep Flappie ?

I've just had my first flight without freezing  since a long time. It might a bit soon for a victory claim but this is a real progress.

I believe I'm not the first one to solve an issue by setting a fixed size page file. Not so sure why I would need it with 32gb, but DCS & Windows do have a lot of mysteries.

I will let you know if this crash is back or gone for good but I need some further testing.

Again Flappie, thank you for your help, insight and availability, you really are a (strong and helpful) pillar of this community.

I often sleep badly, wether I go to bed early or not, so... I often go to bed late.

Thank you for the compliment, and I'm looking forward to reading your feedback.

Another VR freeze after 45mn into the mission . I'm affraid the shiny new pagefile didn't help long.

Nothing fancy in the log, some audio error, but I don't think it's related.

I'm running short on ideas

oh well...

I think the answer might be here :

next step : restart the campaign and get rid of the AI F14, too bad

It's not, indeed. These audio errors are common.

If your freeze always happen when AI Tomcat are RTB, it's probable the Tomcat are the cause of your freeze, yes.

I'm happy to report more than 2 hours straight, with my wingman, on a single  local liberation MP mission.

This includes two successful returns to the super carrier deck for both of us.

No Tomcats=no issue.

Too bad 'cos I love having those big birds around, hopefuly, Heatblur and DCS devs are working on a solution.

[Flappie]

Good! I'm glad to know your PC is fine. That's the most important.

I'll try to reproduce the Tomcat freeze in a short track to help devs.
