Problem with Viper Mini

Hello everyone, my name is Alex, and I have a problem. I've had a Razer Viper Mini for 9 months, and I'm having a specific, strange problem. In all games, more specifically Fortnite, I have big FPS drops, around 80%, when I move the mouse. This is strange, it's never happened to me before. I did several tests with other mice, the FPS is stable, but with the Viper Mini the problem continues. Can anyone know what it is? (FPS drops only happen when I move the Viper Mini. With 150 FPS, Viper Mini reaches 30-20-10 FPS, and with another mouse the fps does not drop)
