DCS just keeps crashing

[SWElynx]

Hi guys, hope to maybe find someone who've had the same issues as myself.

Flying online last evening I started experiencing flickering both in VR (Rift CV1) As well as on the 2d screen.

Eventually the image froze and I was able to end DCS via ctrl alt delete. Retry and could fly a bit longer (5-10 minutes, same thing happens again.)

I try flying without VR alltoghether, and the same thing occurs.
Unable to play for even a few seconds after entering instant action and multiplayer servers.

Now the computer totally freeze and I have to shut it down completly by forcing the power button.

 

One time I was able to get a crash log out and I'll attach it here ofcourse.
What stands out I think is this:

ERROR   DX11BACKEND: DX device removed. Reason: 0x887A0006

 

This happens only in DCS though. Other games work fine.

 

Managed to film some flickering if it could help?

 

 

I have so far:
Updated to newest OB 2.5.6.58125

Updated to newest graphic drivers. 460.89 (for RTX 2080Ti) (And the previous drivers just to make sure)

Downclocked the GPU in both Core and Memory MHz.

Ran a repair of DCS.

Lowered graphic settings to absolute lowest in DCS

Physically removed the GPU used dust off to get any dust off, wasn't really that much there.

 

If anybody have had similar issues or know how to fix this I would be extremely grateful.

Ok, I've had this happen too and it only happens in DCS, rarely in anything else except Metro.

 

For me, and a lot of other people, it's caused by default GPU clocks being much too high. You graphics card and motherboard have a feature called GPU Boost, and it ramps up the GPU clock speed to much higher than the original manufacturer's recommendation under heavy load, which can cause graphical glitches/artifacts and crashing to desktop.

 

In your crash log it says "ERROR   DX11BACKEND: DX device removed" which mine did too, meaning a GPU crash. Obviously you didn't actually remove your graphics card while it was running! It just quit working and DirectX couldn't detect it anymore, and crashed to desktop.

 

The solution for me was to slightly down-clock my GPU. It took about 60-65 MHz downclocking for me, not very much, but if your GPU is running at close to 2000 MHz then it can be a problem, because these chips are actually designed to run at closer to 1700.

 

I can attest that the 460.89 driver is very good, that's not the problem. Try using MSI Afterburner (or something similar) to downclock your GPU and possibly VRAM, by about 200 MHz or so. Try DCS, and see if it runs properly. Slowly increase your GPU clock until it crashes again, and bump it back down.

 

Have fun
