The best gaming mouse on the market right now is the Razer Viper V4 Pro. It's the best because it's light, very well-built, performant, and has great battery life. This last quality—its battery life—is largely thanks to Razer's new FrameSync tech, which is kind of like G-Sync but for a mouse sensor rather than a monitor's refresh rate. And now we have independent testing confirming that the new and innovative tech works as Razer describes it.
We had indirect confirmation of it before just from the fact that the Viper V4 Pro's battery life is so good (180 hours at 1 kHz polling), but it's reassuring and, frankly, just cool to see it confirmed regardless.
