This test simulates the G-SYNC variable refresh rate (VRR) technology.
G-SYNC eliminate stutters by varying the refresh rate to exactly match a fluctuating frame rate. This G-SYNC emulation uses interpolation techniques to emulate the look the smoothly variable refresh rate on NVIDIA G-SYNC displays, with seamless transitions between framerates. This is good for games with variable frame rates.
