This test simulates the FreeSync variable refresh rate (VRR) technology.

FreeSync eliminate stutters by varying the refresh rate to exactly match a fluctuating frame rate. This FreeSync emulation uses interpolation techniques to emulate the look the smoothly variable refresh rate on AMD FreeSync displays, with seamless transitions between framerates. This is good for games with variable frame rates.
