result in tearing where your monitor would essentially try to display multiple frames at once because the GPU has FedEd a new frame in the middle of a refresh cycle the historical solution to this problem was to use a feature called vertical sync or vsync which would lock your graphics card's frame rate to your monitor's refresh rate however if your GPU's frame rate Falls below your monitor's refresh rate vertical sync can cause stuttering as the GPU isn't finished rendering the next frame yet vrr adjusts what your monitor is doing instead making it a very attractive solution while it is
