Instead of setting the camera view individually 4 times and calling SYNC after setting each view, programatically change the camera within the main loop using only one SYNC call. In this example, I splits the screen into 4 views using only 1 set camera view call and one sync. To show that the FPS remains at 60 fps and isn't reporting a false value, I also calculate the frame rate using the timer. The FPS and the timer frame rate should be about the same.
