2.7 Crashing in HP G2 VR after extended session

[Redliner7]

Specs:  11700KF, 32GB RAM, 3080, HP G2.

Issue: After getting this setup to run smoothly at 90FPS, the framerates will drop to about 50 with dips into the 20s and a lot of stuttering after 30mins of running.

I followed the 2 VR guides linked below below in getting my DCS to run well.   Attached are my DCS logs.

This is a brand new build, only a month old btw.  The only mod I run is Kegetys VR shaders mod.  I've ran it disabled with no change in effect after the frame rates have dropped.

Can someone help point me in the right direction with my logs to see what the issues are?  FWIW, I never had any issues with the Rift S crashing or losing frame rates. 

I have also randomly gotten a "Unexpected Kernel Mode trap" BSOD as well after these sessions.  Here was the info in the Windows Event Viewer:

when you say extended what do you mean i just finished a 2 hour mission and i didnt crash? i don't know what is causing it from the data files you have provided, but a BSOD usually comes from a driver failure... are you patched and fully up to date on Windows? Or the Steam VR files ? what version of Windows are you running ?

This is also a useful report. Can I ask you to save this report in *.evtx format?

Thanks for the reply

I'm still testing for maximum FPS, so my 2 test missions is the F14 Instant in Syria against the 2 Vipers and the Lantirn at Night mission at the Marianas.  I test these over and over with different settings and after awhile my FPS degrades until it hops around to 20FPS-60FPS but it's stuttering and pretty much unplayable.  If I reboot the computer, it's between 75-90FPS again.

I'm on Version 21H2 and there's no additional updates required according to Windows Update.

Had similar problems last year when the G2 was new. Things got solved with a new BIOS for my AMD chipset (which you don't have, because you're on Intel), new G2 Firmware and a new cable (different model) for the G2.
Be sure to have the lastest Firmware on the G2 installed and the new G2 cable part No. M52188-001

are you using WMR for Steam VR Beta and or Steam VR Beta, some people have reported stability issues in the past with either beta variant...

I've tried both Beta and Stable Steam VR and neither really makes a difference.  I also read that turning PCIE to Gen 3 over Gen 4 would help.  I haven't gotten a Win BSOD yet thanks to that change but I'm not 100% positive that has solved it.

HP G2 is from Black Friday so it should be the latest variant.  Affirm on the latest firmware as well.

Update: Trying to replicate the factors that cause the issues I've discovered that if I start up the F14 Instant Mission, Clay Dagger Lantirn MIssion in the Marianas - after a fresh reboot the frames are stable at 45fps on the carrier and climb to 70fps in the air. 

If I exit the mission and restart - the frames are jumping from 45fps down to 20fps while it's around 30-45FPS in the air.

But if I restart DCS then the frames climb again to stable 45fps.  Is this some kind of memory leak? 

I've reinstalled WMR and Steam VR as well, deleted metashader and FXO folders to no change in effect. 

Other things I did:  DCS, VR server set a high priority.  Turned off Dropbox and Windows Defender for sessions. Pagefile set to 65k.  

Edit:  Testing this morning, even after restarting DCS - frame rates are still terrible.  A reboot solves the issue for a round of play.   Any help appreciated!
