Preventing Screen Tearing in Unity
Enable V-Sync
The most common solution to screen tearing is enabling Vertical Synchronization (V-Sync). This forces the game’s frame rate to synchronize with the monitor’s refresh rate, reducing discrepancies between the frames the game generates and how the monitor displays them.
void Start() { QualitySettings.vSyncCount = 1; // 1 for V-Sync on }Synchronize Frame Rate
Ensure your game’s frame rate is not exceeding the monitor’s refresh rate. You can limit the FPS in Unity to match your monitor, which helps prevent tearing.

void Start() { Application.targetFrameRate = 60; // Adjust this value to match your monitor's refresh rate }Consider GSync or FreeSync Technologies
If you have compatible hardware, consider using GSync or FreeSync technologies which dynamically adjust the monitor’s refresh rate to match the frame rate of your game. This can significantly decrease screen tearing while minimizing input lag.
Reduce Input Lag
While enabling V-Sync helps with screen tearing, it might introduce input lag. To mitigate this, optimize your scenes and reduce computational overhead to maintain a smooth performance even with V-Sync enabled.
Monitor Refresh Rate
Adjusting the monitor’s refresh rate can also help in reducing screen tearing. If your monitor allows it, try experimenting with different refresh rates in your system settings to find a sweet spot for smooth gameplay.
Use Alternative Rendering Paths
In some cases, using different rendering paths like DirectX or Vulkan can affect how screen tearing manifests. In Unity, you can configure this in the player settings.
