Troubleshooting Gameplay Problems of Modern Windows Port (.NET MAUI WinUI 3) - hyvanmielenpelit/GnollHack GitHub Wiki

Problem: Game Screen Turns White for a While When Starting the Game

Reason

You are using an NVIDIA GPU and with an in-game overlay.

Solution 1: Disable NVIDIA In-Game Overlay

  1. Start Geforce Experience.
  2. Click a gear icon near the top-right corner of the app.
  3. You should be in the General tab.
  4. Find the IN-GAME OVERLAY switch and turn it off.

Solution 2

Wait until the NVIDIA in-game overlay popup has disappeared.

Problem: Game Does Not Use My Dedicated GPU But Integrated One

Reason

Windows detects WinUI 3 apps by default as apps and not games.

Solution 1: Use Windows 11 Settings App to Enable Dedicated GPU

  1. Open the Settings app.
  2. Go to System → Display → Graphics.
  3. Select Microsoft Store app in Add an app.
  4. Click Browse and locate GnollHack.
  5. GnollHack should appear in the list.
  6. Click GnollHack and select Options.
  7. Select High performance and click Save.
  8. Start GnollHack. It should now use the dedicated GPU. It can still do some work on the integrated GPU.

Problem: Red Lines Appear During the Game While Rendering the Screen

Reason

These are rendering artefacts, which are probably caused by video card drivers.
