The number of vertical syncs that should pass between each frame.
An integer.
The default value of QualitySettings.vSyncCount is 0. In the default case, Unity doesn't wait for vertical sync.
Otherwise, the value of vSyncCount must be 1, 2, 3, or 4.
In the Unity Editor, this corresponds to the VSync Count property under Project Settings > Quality > Other.
QualitySettings.vSyncCount specifies the number of screen refreshes your game allows to pass between frames. Depending on your target platform, use either vSyncCount or Application.targetFrameRate to set your application frame rate.
Mobile platforms ignore QualitySettings.vSyncCount. On mobile devices, when a frame is ready, it displays the next time the screen refreshes. You can use Application.targetFrameRate to control the frame rate on mobile platforms.
VR platforms ignore QualitySettings.vSyncCount. Instead, the VR SDK controls the frame rate.
