Mouse lag Big Sur

Using the mouse by simply scrubbing on the dock slows the entire system and apps open in the background. It persists through any app slowing any and everything down even wired or with the included dongle (Razer Mamba Wireless)

However if I use my trackpad the system is perfect without issue. There's some sort of compatibility/connection issue with peripherals on the whole. If any advisor reads this, any feedback on future fixes or updates would be appreciated, cheers.

If it persists too long I'd have no choice but to downgrade to Catalina as it was perfect initially there.

MacBook Pro 13″, macOS 11.0

Hey guys! So I’ve found a quick fix for those who’re using mice which has special software managers. This in turn manipulates the frequencies that Big Sur negates. Long story short, the system lags when it’s trying to process the polling rate above 125Hz of the mouse we’re using. So to fix this you’re going to have to download the manager for that mouse you’re using(for eg. Synapse 3 for Razer, iCue for Corsair, G hub for Logitech, etc). Once you have this downloaded. Go to the “polling rate” tab and switch it to 125Hz.. Done! You’re good to go. Hope this helps!

This happens with me on MacBook Air 2013 and the built in trackpad. xcode is also slow.

Ill unsubscribe from this issue. In my case its only when Xcode is running.

otherwise there are beachballs but there is no lag.

Found the solution for me anyway, Turn off the trackpad...wait for it:) TURN TRACKPAD BACK ON🤦🏻‍♂️ Not sure if this works with third party trackpads or mice, hope it helps someone...
