Constant CTDs with Varjo AERO

[Swooperduper]

I am experiencing constant CTDs while in multiplayer with my Varjo AERO. I notice it mostly when I have a lot of contacts on the Air-to-Air radar in the F-15E. But the issue has progressed pretty much to any module even just sitting on the ramp after about 5 to 10 minutes I just CTD. I am at a loss. I have installed the foveated mod via the instructions here: https://github.com/mbucchia/Varjo-Foveated/wiki  I have used Process Lasso to force DCS.exe to the P-cores on my i9-14900KF. I've set the affinity higher for all the Varjo apps, I've set all other processes to lower affinities. vrmonitor.exe is set just below the Varjo apps. I'm running Ultra Low latency mode and maximum performance power profile in the nvidia settings application. I only run in openXR I do not use steam vr. I've run sfc /scannow for Win11 dism /online /cleanup-image /restorehealth for Win11. I've run the dcsupdater.exe -repair in the command line. I've disabled the in-game VOIP. I need some help figuring out why I'm constantly CTD. Most of my dcs.log files seem to be corrupted... I'll post the ones I was able to succesfully extract.

The first file is a .trk file I just converted it to .zip so I could review it. You can just change the .zip on DDCS-Modern-Syria_0-20231208-195650 to .trk if you need to...

This one looks like a GPU crash:

In your dxdiag logs, we also see that the following apps have crashed a few times:

• AUDIODG.EXE (Microsoft Sound system) through "THXOutAPO-SSE2-v3.dll" (often)
• GvReadVBIOS.exe (often, Gigabyte app))
•  SimAppPro.exe (once)
• VarjoGazeTracking.exe (once)

 

I see that your motherboard BIOS is up-to-date.

I suggest you try and uninstall your GPU driver using DDU, then install a fresh GPU driver.

You can also try running DCS with Varjo gaze tracking disabled to see if the problem comes from it.

Sorry it's been a few days thank you for taking a look at it. I tried rolling back my gpu drivers, same results. Tried updating my drivers to the latest version, same results. Now that I'm back and I have a little bit of time on my hand I'm starting from scratch. Day one when I installed everything I was still on Windows 10 64-bit professional. I seemed to get Great visual fidelity but really choppy frame rates no disconnects because I had everything running on maximum settings. I was told to update to Windows 11 because for my i9-14900 KF Windows 11 was better at managing the onboard chip cache or something for the newer processors so I upgraded to a Windows 11 64-bit professional. That is when I started noticing massive decrease in performance and constant disconnects. So today I'm going to start from zero with Windows 10 and start working forward from there. Hopefully I'll keep a nice detailed progression record so that I can hopefully help other users of the VARJO VR headset.

Did you solve it?  I have a similar setup and just started experiencing big fps drops while taxiing to the runway along a busy parking full of various aircraft styles... big spikes in frametime for 2-3sec.  Goes away once in the air.   Hence curious about what helped u.  Thks
