performance slowly when changing between layouts
In AutoCAD 2018 or even 2021, the software performs slowly when changing between layouts.
The first change to a tab is slower, but consequently new changes after opening the file are also very slow, taking up to 30 seconds if the file has many layouts with several viewports.
The greater the number of viewports per layout, the slower it becomes to switch between layouts, as I increase the viewports by layout, the slower the process becomes, I have already updated the software, put HPMAXLINES to 1000000, I have already made other solutions such as changing the INDEXCTL for 3, or, or UPDATTHUMBNAIL = 7, DISPLAYVIEWCUBEIN2D and DISPLAYVIEWCUBEIN3D as OFF, as you recommend and does not work.
I tried a ZWCAD software and then I don't have that problem, I can have 10 layouts with 20 viewports each layout with the exception of the first layout change, which can take about 10 seconds, the others are very fluid, which is not happening to me in AUTOCAD , I already tested it in version 2021 and it also presents the same problem as in 2018…
My computer has a Ryzen 3950x processor, 64GB of RAM and an Nvidia 2080 Super graphics.
In a file with a reduced number of viewports, there are no big problems, but when I enter the execution phase and I have to create several layouts, with several viewports, this becomes very uncomfortable, I spend a lot of time waiting to switch between layouts.
What makes this performance so slow when switching between layouts in AUTOCAD?
