Basilisk Stutter on MacOS 11.0.1

I have a Razer Basilisk X Hyperspeed, and I just updated my software to Big Sur: 11.0.1. On Catalina, the mouse was working fine, but now it is very scuffed: 1. It stutters a LOT. Basically makes any game unplayable with that mouse. 2. It makes my game laggier but what I find interesting and what stops the lag immediately is when I just move my finger on the trackpad. There is no lag at all. I can't download Synapse because that is only available for Catalina and somewhere before; not for Big Sur. So I was wondering what can I do to reduce this lag and whatever.
