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

2,7 GHz 2‑core processor Intel Core i5
8 GB 1867 MHz DDR3
Intel Iris Graphics 6100 1536 MB

yes, the interface ceases to slow down when switching graphics - well, the question is why should I pay for the laziness of the developers with the laptop autonomy by using radeon videocard

Going to battery under system preferences and unchecking Automatic Graphics Switching fixed this for me.

ever since I updated to big Sur ive been having terrible lag as well. theres a lot new features I like with the ui and looks of the OS but when scrolling, switching apps its completely rubbish

2 month old 2020 13in macbook pro 16g Ram and i7

using a dell 27in S2719DGF currently overclocking the monitor @155hz and its crazy choppy and raggidy when I switch between apps and scrolling through pdfs. especially when using goodnotes, while scrolling through notes it looks like im using a 1990s hp

Hi,
Even i cant watch videos on youtube at 720p. Forget 1080p. It is so lagging. Updating to big sur was a big mistake.

If you are experiencing video lagging try resetting your SMC:

Power off MAC and leave the plug attached
Hold down Shift + Ctrl + Option and Power On button for 10 Secs.
Release buttons and then power on mac.

This should remedy most issues with the new update Happy Crimbo.

After installing big sur, the animation started lagging when scrolling in Safari / notification center. Does anyone have a similar problem? Scrolling occurs in some jerks, and this is on a standard MacBook trackpad. When scrolling through applications or scrolling through the Launchpad, some animation problems are also noticeable . folders in the Launchpad open with some slowing down.

When restoring to Catalina there are no such problems

Macbook Pro 16", typing lag with intel gpu. Safari scrolling lag with both gpu's. All started after big sur update. Hopefully fix is coming.

I found partial solution for me. You need to reduce mouse polling rate to 125-500 in mouse program. Example: Synapse 3 for Razer Mouse. But Synapse 3 dont support macOS, and i reduce this setting via Windows. (has just been installed for some work tasks). I hope its help for you guys.

The SMC reset worked for me. I was skeptical, but the video performance after doing that is now what it used to be before updating to Big Sur. I'm using Mac Air 13 inch, early 2015

This really works!
Just go System Preferences -> Batter -> And Battery in left side menu.
I already wanted to reinstall whole system...

Confirming that the SMC reset made a massive difference for me.
