Measuring the time lag (latency) between a mouse click and the muzzle flash in a video game has been an expensive, lab-only capability. But now, Asus and Nvidia say, you can do it with your PC.
That is, you can do it with a PC with Nvidia’s new GeForce RTX 30-series graphics cards. You’ll also need a certified mouse from Logitech, Razer, or Asus, and a monitor such as the new Asus ROG Swift PG259QNR.
That last letter ‘R’ stands for the Reflex Latency Analyzer capability of the G-Sync monitor. Such capability would cost more than $7,000 in high-speed cameras and equipment. The latency will be displayed in real-time on the monitor’s OSD. It’ll even break down where that latency is occurring—whether it’s the mouse, the CPU, the GPU, or the display.
