How to Fix "Game Error [128] - DirectX Fatal Error"

Simple Steps to Fix the Problem

1. Update Your Graphics Drivers

  • Press Win + X > Device Manager
  • Expand Display adapters > Right-click your GPU > Update driver
  • Select Search automatically for drivers
Why? 90% of DirectX errors are fixed by current GPU drivers

2. Change Game Display Settings

Launch the game > Go to Video/Graphics Settings
Try:
  • Lower resolution (e.g., 1920×1080 → 1600×900)
  • Windowed or Borderless Fullscreen mode
  • Different refresh rate (60Hz instead of 144Hz)
Why? Some resolutions/refresh rates conflict with DirectX

3. Install Latest DirectX Runtime

  • Download from Microsoft: DirectX End-User Runtime
  • Run the installer > Restart your PC
Why? Games require specific DirectX components

4. Verify Game Files

  • Steam: Library > Right-click game > Properties > Local Files > Verify Integrity
  • Epic: Library > 3 dots on game > Verify
  • Battle.net: Options > Scan and Repair
Why? Corrupted game files cause DirectX initialization failures

5. Disable Fullscreen Optimizations

  • Right-click game executable > Properties
  • Compatibility tab > Check Disable fullscreen optimizations
  • Click Change high DPI settings > Check Override high DPI scaling
Why? Windows' fullscreen handling can conflict with DirectX

6. Clean Reinstall Graphics Drivers

  • Download Display Driver Uninstaller (DDU)
  • Boot in Safe Mode > Run DDU > Select Clean and restart
  • Install fresh drivers from NVIDIA/AMD/Intel website
Why? Removes all driver conflicts completely
