QualitySettings.vSyncCount

描述

垂直同步数。

The number of VSyncs that should pass between each frame. Use 'Don't Sync' (0) to not wait for VSync. Value must be 0, 1 or 2.

Windows Store Apps: It's not possible to disable VSync when DirectX 11 is used due to platform limitations, you can disable VSync if DirectX 12 is used.

using UnityEngine;
using System.Collections;

public class ExampleClass : MonoBehaviour {
    void Example() {
        QualitySettings.vSyncCount = 1;
    }
}
