How can I disable VSync in Unity to improve the frame rate of my game?

Disabling VSync in Unity to Improve Frame Rate

Vertical Synchronization (VSync) is a graphics technology that synchronizes the frame rate of a game with the refresh rate of the monitor. While VSync can reduce screen tearing, it may introduce input latency and affect frame rate stability. Here are the steps to disable VSync in Unity:

Changing Unity Quality Settings

To disable VSync in Unity, you need to adjust the Quality settings:

Try playing right now!

1. Open your Unity project.
2. Navigate to Edit > Project Settings > Quality.
3. In the Quality window, you will see different levels (e.g., Low, Medium, High). Click the right arrow icon next to the level you want to modify.
4. Scroll down to find the VSync Count option.
5. Set the VSync Count to Don’t Sync to disable VSync.

Disabling VSync at Runtime

You can also control VSync via scripting to dynamically change settings at runtime:

void Start() {   // Disable VSync at runtime   QualitySettings.vSyncCount = 0; }

Alternative Method: Using Frame Rate Settings

Another way to improve performance is to explicitly control the frame rate:

void Start() {   // Limit the target frame rate to improve performance   Application.targetFrameRate = 60; }

Pros and Cons of Disabling VSync

• Pros: Potentially reduces input latency and improves frame rate.
• Cons: May result in screen tearing when frame rate exceeds the monitor’s refresh rate.

Consider testing and profiling your game to ensure the best performance outcomes tailored to your specific needs and device capabilities.
