Auto CAD lagging issue in double viewport

[Anonymous]

I recently got a new laptop, a Lenovo X1 Extreme with 32 GB RAM. I thought it was enough to run AutoCAD and it was fine until I tried to make 2 viewports on the same layout and things got very glitchy. 

I tried to use command VPFREEZER to turn off layer in one viewport and the same objects disappear on the other viewport. I undo the task, redo it and it works. 

Wonder if this is an issue with my laptop strength?

Hi,

>> I undo the task, redo it and it works. 

is that mean that lagging is disappear ? if you restart your AutoCAD , any changes ?

Lagging did not disappear. Lags still occur when I try enter viewport view.

I tried to restart auto cad. Same issue happened. I then undo the task I just did and rewind commands until I saw my objects again.

disabling hardware acceleration from GRAPHICSCONFIG command make any changes ?

also make sure that you have the latest updates from your Autodesk Desktop App .

Glitchy?

Post a screenshot of your ABOUT command pop-up, as well as your GRAPHICSCONFIG command pop-up please.
