Simulated Variable Refresh Rate on any monitor without G-SYNC or FreeSync

A new TestUFO animation simulates the appearance of variable refresh rates (VRR) on any display even without VRR support. This animation works on any monitor, laptop, iPad, and most smartphones.

Without variable refresh rates, you get stutters and tearing. Variable refresh rates displays allow seamless frame rate transitions with reduced lag, judder, and tearing.

That said, hardware-based variable refresh rate displays such as FreeSync and G-SYNC look even better than this software-based simulation.
