Scrolling is not smooth and lags when panning

[Anonymous]

I've recently updated to macOS Big Sur and noticed that when I scroll in the model space and layout it is very jittery and lags. Its so annoying since I cant work fast since I have to wait for it to catch up on what I want it do do. Im asking if there's any solution to the lagginess in scrolling and panning or is it because AutoCAD 2018 isn't fully updated to macOS Big Sur or is it because macOS Big Sur still has bugs? HELP I'm so annoyed already...

PS. before updating the scrolling and panning didn't lag at all.

Hi Samuel,

AutoCAD 2018 for Mac is not officially supported on new macOS Big Sur, and will not be supported.

Only 2019 version with 2019.2 Update, 2020 with 2020.2 Update and 2021 with 2021.1 Update are supported on Big Sur.

So you need to upgrade your AutoCAD or to downgrade to macOS Catalina.
