Hi! I’ve encountered a problem. I’ll describe it briefly:

  1. I set Direct3D 11 in the settings.
  2. I restart the game - everything works for me.
  3. I restart the game twice in a row - the system automatically sets Direct3D 12

This is what helped me solve my problem:

  1. I launched War Thunder and set Direct3D 12 in the settings. closed the game.
    2 .In Steam → Library → War Thunder → Properties → Launch Options, enter “renderer:d3d11 -driver:d3d11”
  2. Go to the game folder: (for example) D:\steam\steamapps\common\War Thunder\config.blk and Find the line: driver:t=“dx12”. Replace with: driver:t=“dx11”
  3. Close Notepad. Right-click config.blk → Properties → check the Read-only box.
  4. Launch the game. In the graphics settings, make sure Direct3D 11 is set. To be on the safe side, restart the game 2-3 times and check each time.

When you’re done, write whether it worked or not.

If you have GeForce GPU, can you check Nvidia App settings (graphic section)?
It’s possible that app force settings on WT there.
