A new Game Ready driver, version 456.55, is available today for owners of GeForce graphics cards. It enables NVIDIA Reflex, the latency-lowering technology announced recently by NVIDIA, in Call of Duty: Modern Warfare and its free-to-play Battle Royale spin-off, Call of Duty: Warzone.

According to NVIDIA, this can significantly reduce system latency, particularly when using older GeForce graphics cards. For example, in the scenario tested in the chart below, the GTX 1660 Super gains 10ms by activating NVIDIA Reflex, the RTX 2060 Super shelves 7ms, and the brand new RTX 3080 2ms. NVIDIA Reflex launched on Valorant and Fortnite recently and is expected to become available on other competitive games such as Apex Legends and Destiny 2, not to mention the upcoming Call of Duty: Black Ops Cold War.
