A method is provided to measure a relative frame rate of a remote desktop on a first computer and accessed by a second computer. The method includes playing a video timestamp on the remote desktop at the first computer where the video timestamp includes unique timestamps, screen capturing the remote desktop at the first computer and the second computer, determining a first frame rate at the second computer based on the screen capturing the remote desktop at the second computer, determining a second frame rate at the first computer based on the screen capturing the remote desktop at the first computer, and determining the relative frame rate as a ratio between the first and the second frame rates.
