Game constantly crashing / Video driver hung / PC restarts (Hardware tested & OK)

So I’ve been playing War Thunder and the game was running super smooth for the last few weeks, but 3 days ago it started constantly crashing mid-game. It either shows a small window saying “send crash dump to developers”, goes to a black screen and says “video driver hung and was restarted”, or sometimes even restarts my PC.

I tried playing other games like Rainbow Six Siege on max settings and also ran a 3DMark benchmark right after War Thunder crashed to see if the problem was my PC, but everything passed without any issues.

What I’ve already tried:

  • No mods or custom content installed (100% vanilla game)
  • Cleared the game cache and GPU cache
  • Switched between DirectX 11 and 12
  • Cleaned GPU drivers using DDU and tested both the latest and previous driver versions
  • Verified the integrity of the game files
  • Used the standalone War Thunder launcher instead of Steam

Nothing seems to help. Is there anything else I can try?
