DCS crashing after some time

[siwymaligan]

Hi,

My problems started when DCS crashed on Caucasus after about 10mins of flying.

Then at syria it started crashing at Mj-24 startup.

 

What I did since then:

- repairing DCS
- reinstalling it from scratch, with importing only controlls
- deleting metashaders2, fxo and bazar/shaders folders
- reinstalling windows together with disk formating
- installing newest and older nvidia drivers (465.89, 466.47, 466.77, 471.11)
- installing DX11 and 12

- decreasing clocks of GPU and VRAM

 

only difference is, that it crashes now after about 30mins.

Here's latest log:

Have you tried just running everything stock? No overclocking or undervolting?

[siwymaligan]

*Underclocking or overvolting- I wanted to decrease performance of GPU

 

I tried. No joy

Hi. You're having the dreaded "DXGI_ERROR_DEVICE_REMOVED" crashes:

Usual causes are:

• GPU / RAM / CPU overclocking or undervolting (recent example)
• a faulty or insufficient PSU
• dust clogging the CPU

Some weeks ago, someone said his Corsair iCUE software was messing with his SSD. As soon as he disabled it, his DCS stopped crashing. If iCUE is installed on your computer, you want to give it a go.

- My GPU, CPU and RAM are running at stock clocks. No undervolting or overclocking was made. Only once I tried DOWNclocking or OVERvolting. It didn't change anything.

- PSU is OZC ZT 650W- worked fine with Radeon 5700 XT, which has bigger power consumption

- CPU is running at 40deg C, with new bequiet dark rock pro 4, so it's not overheating

 

I don't have Corsair ICUE installed

Do you have nVidia in-game overlay enabled? I know that this can sometimes cause issues

 

Alternatively, there are pages such as https://thegeekpage.com/dxgi-error-device-removed/ that provide some possible solutions (all at your own risk of course)

@siwymaliganThis sometimes works when DCS freezes. Maybe it will help you:

1. Empty "C:\Users\username\AppData\Local\Temp\DCS.openbeta"
2. Empty "C:\ProgramData\NVIDIA Corporation\NV_Cache" (Windows might refuse to delete some files unrelated to DCS - just hit "Ignore")
