Solution Steps
- 1 Force the game to use DirectX 12 or Vulkan instead of DirectX 11. For Steam, right-click the game in your library, select 'Properties', and in 'Launch Options' type '-force-d3d12' (for DX12) or '-force-vulkan' (for Vulkan). For other launchers, look for a similar option. This bypasses the problematic DX11 renderer.
- 2 Update your graphics drivers. Newer drivers often improve DirectX 12 and Vulkan support. Follow the steps in the first guide to install the latest driver.
- 3 If forcing DX12 or Vulkan doesn't work, try running the game in windowed mode. Right-click the game's executable, go to 'Properties' → 'Compatibility', and check 'Run in 640x480 resolution' or 'Run in compatibility mode for Windows 8'. This can sometimes fix rendering issues.
- 4 Check if your GPU supports DirectX 11. Press Windows key + R, type 'dxdiag' and press Enter. Look at the 'Display' tab — under 'Drivers', it shows the feature levels. If it doesn't show 11_0, your GPU is too old for the game.
- 5 If the game has a 'Graphics API' setting in its options menu, try switching it to 'DirectX 12' or 'Vulkan' from there.
