Yu-Gi-Oh! Master Duel is a globally popular card game, but some players experience lag, login failures, black screens, or low FPS on PC and consoles.  This guide offers eight proven solutions to help you restore a smooth gaming experience.

Method 1: Optimize Your Network with LagoFast Game Booster

High latency and login issues often stem from unstable cross-region server connections. LagoFast Game Booster intelligently selects low-latency nodes and optimizes data transmission routes, significantly reducing network fluctuations.  Launch the booster, search for "Yu-Gi-Oh! Master Duel," select the server matching your account region (e.g., Japan/International), and restart the game after acceleration is complete.

Method 2: Verify Game File Integrity

Black screens or crashes on startup can be caused by corrupted game files. Steam users should right-click the game in their library, go to "Properties - Local Files - Verify Integrity of Game Files." Console players can try uninstalling and reinstalling the game. This process compares local files with the official server's original data, automatically repairing missing or corrupted files.

Method 3: Update Graphics Drivers

Low FPS or stuttering is often due to outdated graphics drivers. NVIDIA users should open GeForce Experience and click "Drivers - Check for Updates." AMD users can get the latest drivers through the "Updates" function in Radeon Settings.  Ensure you restart your computer after installation and set the game to "High Performance" in your graphics control panel.

Method 4: Close Background Applications

Background processes (like antivirus software, browsers, and streaming tools) can compete for system resources, leading to lower FPS or game freezes. Press "Ctrl+Shift+Esc" to open Task Manager, and end unnecessary programs (like Antivirus, Chrome) in the "Processes" tab.  Prioritize the game by setting its priority to "High."

Method 5: Adjust System Virtual Memory

Insufficient memory can cause black screens or crashes. Right-click "This PC," go to "Properties - Advanced System Settings - Advanced - Performance Settings - Advanced - Change Virtual Memory." Uncheck "Automatically manage paging file size for all drives," select your system drive, click "Custom size," and set both the initial and maximum size to 1.5 times your physical memory (e.g., 24576MB for 16GB RAM). Save and restart.

Method 6: Disable Fullscreen Optimizations and DPI Scaling

Compatibility issues between the game and system display settings can cause windowed black screens. Right-click the game's shortcut, go to "Properties - Compatibility," check "Disable fullscreen optimizations" and "Override high DPI scaling behavior," and select "Application" in the dropdown menu. This prevents system scaling from interfering with game rendering.

Method 7: Reset Network Configuration

IP conflicts or DNS issues can prevent server connections. Run Command Prompt as administrator and enter the following commands: "netsh winsock reset," "netsh int ip reset," and "ipconfig /flushdns." Restart your computer. If the issue persists, try manually changing your DNS to Google's 8.8.8.8 or Cloudflare's 1.1.1.1.

Method 8: Lower In-Game Graphics Settings

For low-end PCs with FPS issues, reduce graphics settings. In the game settings, set the resolution to 75% of your native resolution, disable anti-aliasing, dynamic shadows, and ambient occlusion, and cap the frame rate at 60 FPS. If using a dedicated GPU, ensure the game uses it in Windows "Graphics Settings."

These methods address common network, hardware, system, and game-specific issues. Try them sequentially. If the problem persists, contact official support with log files for further investigation.
