DXGI_ERROR_DEVICE_REMOVED or DEVICE_HUNG

What you see

• The game closes with a DXGI error
• The screen may flicker or go black first
• Other games or the desktop may also glitch

What usually causes it

• The graphics driver stopped responding and Windows reset it
• Unstable GPU overclock or undervolt (including 'factory OC' profiles in vendor tools)
• Overheating or an underpowered / failing power supply
• A driver version that is buggy for this card

Worth checking first

• Check GPU driver version and how old it is
• Check whether any overclocking tool is running (MSI Afterburner, vendor tuning software)
• Check GPU temperatures during play if you have a monitor for it
• Check whether the same happens in other games

Safe steps, one at a time

• Update the graphics driver from AMD's, NVIDIA's or Intel's own website
• Reset any GPU overclock or undervolt to stock while testing
• Make sure the PC has airflow and the fans are working
• If it only started after a recent driver update, install the previous driver version

When to stop and ask staff

Not an AGN issue in itself. Escalate if several players report it in the same AGN location, which can indicate a heavy streamed asset.
