D3D device is your GPU. This error is saying that the game lost communication with your graphics card.

This is usually not a good thing.

  1. Best case, driver issue. Update your drivers using a "clean install".
  2. Next best, overheating. Make sure you've got decent airflow, and monitor your card's temperatures.
  3. Next, your PSU may be insufficient to drive the card and all the fans and such needed at the same time. PSUs do have lower power capabilities over time, so maybe look into how much you're drawing vs producing.
  4. Worst case, your GPU has a hardware issue and may be dying.

Good luck.
