In the Editor, targetFrameRate affects only the Game View. This default rate depends on the platform: - On standalone platforms the default frame rate is the maximum achievable frame rate. The default targetFrameRate is a special value of -1, which indicates that the game should render at the platform's default frame rate. For example, if the platform's default render rate is 60 frames per second and vSyncCount is set to 2, the game will target 30 frames per second. Instructs the game to try to render at a specified frame rate. We will be getting our X and Y values from input from our mouse. For this tutorial, however, we only need to be concerned about the X and Y axis, since our character only needs to look up/down and side-to-side. There can be fluctuations due to platform specifics, or the game might not achieve the frame rate because the device is too slow.ДЄdditionally if the QualitySettings.vSyncCount property is set, the targetFrameRate will be ignored and instead the game will use the vSyncCount and the platform's default render rate to determine the target frame rate. When making a 3D game, you usually have 3 axis to worry about: X, Y, and Z. Setting targetFrameRate does not guarantee that frame rate will be achieved. When using VR Unity will use the target frame rate specified by the SDK and ignores values specified by the game. Non-default values are only recommended if you want to throttle CPU usage on WebGL.

On WebGL the default value lets the browser choose the frame rate to match its render loop timing which generally produces the smoothest results.

Instead, the device displays frames on the first possible VBlank after the frame is ready and your application achieves the targetFrameRate. iOS ignores the QualitySettings.vSyncCount setting. Note: If you set the targetFrameRate to the refresh rate divided by an integer, the integer division leads to the same effective fps as setting QualitySettings.vSyncCount to the same value as that integer. Otherwise, the resulting frame rate is always lower than targetFrameRate. Therefore, you should set the targetFrameRate to either -1, or a value equal to the screen's refresh rate, or the refresh rate divided by an integer. Additionally, all mobile platforms can only display frames on a VBlank. Screen.currentResolution contains the screen's refresh rate. All mobile platforms have a fix cap for their maximum achievable frame rate, that is equal to the refresh rate of the screen (60 Hz = 60 fps, 40 Hz = 40 fps. Typically on mobile platforms the default frame rate is 30 frames per second. On mobile platforms the default frame rate is less than the maximum achievable frame rate due to the need to conserve battery power. On standalone platforms the default frame rate is the maximum achievable frame rate. This default rate depends on the platform:
