 Hello,

I'm using a quest 3 via steamVR wireless link.  The game loads fine in multiplayer and after a few minutes, the game freezes, my PC fans spool down, PC freezes and when it comes back I get the bug reporting tool popping up.  This started after the last update as it was fine before.

 

 

 

PC Specs

9800X3d

X870E Asus Hero

96 GB DDR5 

  • DDR5 8000 (PC5 64000)

2TB NVME Seagate Firecuda

Asus 4090

 

Running AI overclock via armoury Crate

Discord

OBS (streaming Software)

SRS

USB wattage watcher (ASUS)

Lian Li L Connect 3 (For CPU Fan Control Left on Full SP for DCS, other fans spool down, not these)

Simapp pro

And google chrome for music and streaming to  youtube.

 

It happened while I was live streaming and when I wasn't, I'm also listening to music on a web browser as well.

Log is spammed with DXGI_ERROR_DEVICE_REMOVED errors. Generally a GPU issue of some description.

Dropped your log into the DCS log analyzer which verified the same.

  • There is a GPU-related error
  • Remove any overclocking from your GPU. Some GPUs may come with a factory overclock, you can confirm whether or not this is the case with MSI Afterburner
  • Uninstall your GPU driver with DDU and install a clean one.

See also this DCS FAQ article on it: https://www.digitalcombatsimulator.com/en/support/faq/startup/#3312253

You also have a dxgi.dll file in the DCS bin folder. I'm aware of only two reason why this would be placed there, this does not ship with the game. Remove that as well as it has been known to cause crashes. It may be fine if you resolve the other GPU issue, however I would recommend trying that.

Some additional tuning advice. The SSAO and SSLR are a performance hit with little benefit.

  • Turn off SSAO.
  • Turn off Depth of Field.
  • Disable civil traffic.
  • Turn off SSLR.

I see you also have the VirtualDesktop API layer, any reason you're not using that vs. SteamLink? Will be more performant and less VRAM overhead than that introduced by SteamVR.

I finally got some time off work to play around with this. 

Driver uninstalled with DDU, driver reinstalled (however NVidia did release a new Driver)

Updated the bios

Installed MSI afterburner, confirmed no GPU overclock

 

Anyway, thank you and the steps above worked.
