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

After getting my reply video up, I read the comments on yvesclv's video and one of the commenters mentioned that the reason wired mice are causing issues with Big Sur is because their Polling Rate (or how many times the mouse reports its position back to the Mac/PC) is too high. Higher polling rates are great for PC gaming, but Big Sur seems to be liking the "classic" value of 125Hz.

I'm using a Logitech G502 wired mouse and using the G HUB application, I was able to see my mouse's polling rate was at 1000 (!!!) and was able to drop it down to 125. The lag went away! Depending on your make and model of mouse, check to see if there's MacOS software you can download to change the polling rate (and if there's only Windows software, download the software to a Windows machine temporarily and save the settings to the mouse directly, so it's remembered when reconnected to your Mac).

Hopefully, this temporary workaround helps you out until Apple pushes out a true fix!

I'm having the same problem since the last update. My Magic Mouse starts to lag at the same time every day and I have to restart my computer. I had the same problem with my track pad...it lagged too.

This is still happening! I've replaced the mouse with a new Apple one. I've tried my Track Pad. Nothing helps. It locks up at least once a day and I have to restart my computer to get it to start moving again. This is killing my productivity with working from home. Apple really needs to fix this. It makes my computer useless when it's locked up and it's not always a good time for me to restart it and get back to where I was when the mouse stopped working.

Hey! I have this problem and I am using a mouse with the software for which that I cannot access. I have a Model O Glorious. If you find a way to change the weird sort of smoothness in the mouse on Bigsur please let me know as I am very frustrated with this.

Yes. I have this problem, when I was playing minecraft, my mamba wireless mouse was laggy, but the trackpad worked smooth. I hope apple responds and tells us how to fix this issue.
