Same configuration, same problems.

Lags a lot. Have reset SMC, but it didn't help.

Please do something with it.

MacBook Pro (15-inch, 2019)

Same here. Scrolling, typing, selecting menu items, clicking buttons, selecting finder windows - lags like crazy. Often the wheel is spinning for several minutes, sometimes the system appears simply to be frozen.

Ran CleanMyMac, reset SMC, PR Ram. Turned off animations and transparency. The latter seemed to have helped a bit, but still - it is unacceptable.

Even as I type this, the wheel appears, input puffers and mouse movements, clicks and keystrokes seem to be buffered, the fired all at once.

Catalina worked perfectly fine with all graphical enhancements turned on.

Same issues here on my 13" 2020 Macbook Pro i5. Stutter animation, hangs and delays even with Apple's stock applications.
Hope Apple will fix it in the next update. Big Sur is such a let down.

Macbook Pro 2017 13". Updated to Big Sur. Nothing but LAG. Gaming Lags. Normal Desktop use Lags. Hangs, freezing, dock icon is absolutely jittery. Never seen it this bad before.

Playing games in Steam, e.g. Borderlands 2, on my

Pro (13-inch, 2018,
2,3 GHz Quad-Core Intel Core i5
6 GB 2133 MHz LPDDR3
Intel Iris Plus Graphics 655 1536 MB
running Mac OS 11.0.1 Big Sur

is really laggy even after i turned down resolution and all other graphic enhancements to low or off.
Before upgrading everything was fine on MAX settings.
Cheers

Same for me on an MBP 16" 2019 model.

Its laggy even to type in Pages. Mac OS Big Sur 11.0.1.

It seems to be related to the GPU, because turning off the automatic graphics card switching seems to improve the situation at least temporary and superficial.

It remains unclear, if it is related to a problem with Intel GPU or GPU in general and the reason it doesn't appear on the AMD GPU (5500 M, 4GB) may just be related to its increased computing power.

Hopes are up for a quick fix, I don't like the idea of going back to Catalina, but as it is right now, it destroys all the fluidity in the workflows I love so much while using my Mac.

Best regards

Same over here, MCP 2016 i7 2,6ghz.
The only way to improve is to deactivate automatic graphics switching in the battery settings and always use the secondary more powerful graphics card (I have the 2gb radeon 450).
Let's hope for a quick fix as it drains my battery pretty quickly

Same here, after that Gatekeeper incident, things have been very poor in general. Beach balling during the simplest tasks. Catalina seems very nice right now.

Macbook Pro 2020 after big sur update horribly laggy. I used to play Dota 2 on MBP late 2013 without any issues and now this 7 year old game is unplayable on latest MBP that cost me 2500€. This is a joke, I am seriously thinking to finally switch to windows again

A similar problem. slows down graphics, scrolling, animation.

lags when typing and erasing text, lags in any applications, especially noticeable when scrolling through pages in safari.
MBP 13 2020 i5 16gb-ram

Same macbook as OP and Dota 2 is basically impossible to play after updating. Constantly hangs and/or freezes in game.

I'm also having lag problems all of a sudden. I play The Sims 4, and prior to this, it has run beautifully. I've been able to switch between apps, run multiple things at a time, use Apple Music, use Safari, chat on iMessage, whatever. Suddenly, if I'm on the game, I can't so much as type a word without a multiple-second lag. All the fluidity between programs that I loved so much is flat-out gone.

Furthermore, even when that game is closed, my computer just doesn't run as well. It runs hot, and can't multitask like it used to be able to. The activity monitor says that, at worst, I'm using approximately 54% of my system at a given time. This wasn't an issue until Big Sur was downloaded onto my computer. I'm seriously considering going back to Catalina until it gets resolved. Why do we need a new OS every year, anyway?

MBP with i9 and 16gb and my MacBook is lagging when I log in. Never did this until the Big Sur update.

to narrow it down, please look in /Library/Logs/DiagnosticReports and analyse .diag reports,

what i did notice is that Big Sur has issues with com.apple.AppleUserHIDDrivers, as you move the mouse, that driver uses a lot of cpu, triggering the cpu limit that in turn starts to run diagnostics further worsening the issue.

games are currently unplayable on Big Sur unless you reduce polling rate of your mouse.

Hello everyone.
I too have the following problems after upgrading to Big Sure:

  • Lag cursor

  • blurry login image

It seems I solved them by simply turning off the FileVault.
Hopefully, Apple will release an update right away.
