Hello! Help please, after updating the system to Big Sur, my MacBook Pro 13 began to slow down, previously there were no such problems.

Only One Fix is Download Easyres App on App Store and put Resolution to Retina 1x 2048x1280.

Problem Solved.

now try lagging apps, like  tv, maximise and minimise apps.........

I have a similar issue. I have no major applications installed except Ableton Live 11 and Chrome. Scrolling through webpages is choppy and using Ableton is very choppy and laggy (Even with an empty arrangement). Performance is not the issue as I'm not even close to using these apps to the fullest extent.

FIX*

I had the exact same problem. Lag on Youtube, desktop videos and Adobe Premiere pro playback.

The answer is to reset the PRAM.

Press and holding the Command, Option, P, and R keys right as you turn the computer on for 20-30 seconds. You'll hear the startup sound twice over this time. After the second startup chime let go. It will chime for a third time and startup. Carry on as normal.

At least, this worked for my Macbook Pro 2015.

I had the same issue and finally managed to fix it, at least for me.

I have 2019 16" almost maxed out configuration MacBook Pro.
Everything was super smooth until I upgraded Mac OS to BigSur.
After upgrade all animations were lagging. Especially moving the windows around was very laggy and the issue was especially bad when I had external monitor connected.

I tried multiple things including SMC reset, NVRAM/PRAM reset etc. These helped a bit sometimes but the issue came back within minutes.
Finally what really worked was to completely factory reset my MacBook. I went to recovery mode and first erased all volumes and then reinstalled Big Sur. After fresh install the lag went away and everything is super smooth again, even with external monitors connected.

Can't say it will work for all, but for me it did the trick

The issue I am having is typing lag problems when using intel gpu.
I have Macbook pro 16" 2019.

The solution (until fixed by Apple) is to force the use of the more powerful, Discrete Graphics card in your MBP. Simply install a tool like Gfx Card status and make sure you set it to discrete only.

Same issue, nothing is opened, and it takes like 5 minutes to open the settings.
Worst version ever.

MBP 16 inch with a i9 and 5500m. I cant do any cpu intensive things without getting 6 fps on my Mac, this never happened on Catalina and I am very annoyed and im probably going to buy a windows laptop if this isn't fixed.

Same issue on my 13 inch 2019 4TB3 MacBook Pro
I5 8579U
16GB RAM
intel 655

it stutters even if I’m not doing nothing and switch desktop or resize a window, the weird thing is that sometimes it doesn’t happens and it is smooth.

I hope in 11.3 otherwise I think I’ll just downgrade to Catalina (although I really like the new UI)

Okay so i was having the same issue drove me nutz two hdmi external monitors with big slur brand new laptop... almost went back to a 5 year old laptop,,, the itermittent lagging was pissing me off very annoying... I research and tried all sorts of things like turning the auto switch graphics in battery settings... nothing... so i was about to wipe this thing and by habit just turned off all my cloud data backup ,,, pretty much anything to do with the icloud and programs sending / storing data to it i turned off now things are working... who the hell knows hope this helped... no lag.

Same problem on air 13-inch, Early 2015, i7, 8 Go 1600 MHz DDR3 with the update big sur 11.2.3. The only solution I've found is to open a new user session to improve the response of the finder

it's because of NVRAM or PRAM ..You just need to reset it .Google it hoe to reset NVRAM.Good to go.

a 3000€ mpb 16 that lags when the gpu is off, this is not acceptable. Any 500 € windows laptop currently delivers a smoother user experience... so annoying...
