Screen tearing is a common issue in arcade game machines, where the display shows parts of multiple frames at once, disrupting gameplay. Here are the most effective methods to prevent it:

1. VSync (Vertical Synchronization): This technology synchronizes the game's frame rate with the monitor's refresh rate, eliminating tearing by ensuring frames are displayed in sync.

2. Adaptive Sync (FreeSync/G-Sync): These advanced solutions dynamically adjust the monitor's refresh rate to match the game's frame rate, providing smoother visuals without tearing.

3. Frame Rate Limiting: Capping the game's frame rate slightly below the monitor's refresh rate can reduce tearing by preventing frame overload.

4. Double Buffering/Triple Buffering: These rendering techniques store extra frames in buffers to ensure smooth transitions and minimize tearing.

5. High Refresh Rate Monitors: Using monitors with higher refresh rates (e.g., 120Hz or 144Hz) reduces the visibility of tearing by displaying frames more frequently.

By implementing these methods, arcade game operators can deliver a seamless and immersive gaming experience.
