I recently updated to macOS Big Sur, and I wanted to use my external mouse for work and gaming. I plugged in my mouse using a USB dongle, but every time I moved the mouse, the screen would freeze. In the games that I was playing, if I didn't move my mouse, I was getting around 80 FPS but as soon as I started moving my mouse, my frames would drop significantly, to around 15 FPS, but they would improve as soon as I stopped moving my mouse. This issue doesn't happen at all when I use the trackpad. Is there any fix for this issue?

  • I plugged in my mouse using a USB dongle, What type of dongle? Is it for the mouse itself (like Logitech) or some 3rd party brand? – Allan Nov 27 '20 at 18:17
  • It's a USB-C hub that I attach to my MacBook so I can plug in USB-A devices. I am using a Razer Deathadder wired mouse, and I plug the mouse USB into my USB hub. – Tushar Nov 27 '20 at 18:53
  • I've seen it before.... Discount hubs can cause all sorts of issues. Get a proper USB-C hub that only gives you more USB Ports not a multi function hub with ports, video, Ethernet, etc. Anker, Plugable and StarTech are all go-to brands IMO. Yes, they cost more but they pay for themselves with the issues you don't have to deal with – Allan Nov 27 '20 at 19:08
  • I only recently started having this issue. I have used my mouse with this USB-C hub before and it worked perfectly fine. I will get a better USB hub and let you know though. – Tushar Nov 28 '20 at 14:18
  • I got the USB hub from Anker that you had linked but I am still having the same issue. Thoughts? – Tushar Nov 30 '20 at 0:20

I have been experiencing a similar problem with my Logitech G Pro Wireless mouse plugged into an Anker hub. I believe I have resolved my issue by changing the mouse's polling rate from 1000 to 250 in the G Hub software for the mouse. You may try changing the polling rate, if your mouse supports it, and see if that helps with your issue.
