Hi
I hope someone can help me here. I got me a new PC in January and since then i cannot play COH2 anymore. All other games are running fine.

When the match starts the game crashes to desktop within the first 3 minutes, mostly. If it does not crash, it will randomly crash during the match. The warning.log file always say the following after each crash:

Error: DXGI_ERROR_DEVICE_REMOVED
Desc: Removed because DXGI_ERROR_DEVICE_HUNG
Code: 5, Facility: 2170, Severity: 1
Call: [pSwapChain->SetFullscreenState( bFullScreenMode ? TRUE : FALSE, nullptr )]
22:02:07.49 DB -- Unable to load symbols.
22:02:07.49 d3d11 -- Display device has been removed. Please check for newer display drivers.

What i have tried so far:
- All Radeon versions since november 2019
- always newest BIOS (current Version 2607)
- Chipset driver always newest
- fresh install of the game many times
- verified game cache in steam many times
- Different compability modes (Windows XP to Windows 8, run as administrator, ...)
- PCIe set to Gen3
- XMP On/Off
- different Startoptions (-refresh 60, ...)
- Different resolutions and grahpic settings in game and radeon driver
- No Software running in the background (MSI Afterburner, Anti-Virus, ...)
... and probably some things i already forgot.

My PC Specs
CPU: Ryzen 5 3600
GPU: RX 5700XT Red Devil
RAM: DDR4 32 GB @ 2133 MHz
Mainboard: Asus TUF Gaming X570-Plus WiFi
SSD: Silicon Power PCIe M.2 NVMe SSD M.2 1TB
Power supply: Bequit 550W straight power 11

I appreciate any help and try out anything to make the game work

Cheers
