I am using AC21 on a small project and find some of its operations much slower that I am used to in previous versions. When I select la working on a model, the scrolled list takes measurable time to appear. When I scroll this list up or down, it takes measurable seconds to actually scroll and it stops and starts. The response to menu selections is also sometimes tardy. I've never had this with previous AC versions.

Am I alone in finding this?

No, you're not alone
I'm working on 150mb file project. Not big.
When I pass from a view to another view it takes up to a couple of seconds (and more in many cases) to redraw the plan ... I'm a bit disappointed. I bought a new machine in June with many cores in order to exploit the multi tasking but what I see a normale "behaviour", just a couple of cores working except for rendering where it runs all the cores ...
In order to speed up the things I had to disable the background update.
I found AC21 much slower than AC19 (never tried AC20).
Hope next versions will be faster and will be really multi tasking.

Alemanda, the post you were referring to was removed because it was Spam so your comment is without context.

One of my guys had a new machine that was going slow with version 20.
Info Box would take a couple of seconds to populate.
Turned out he had palettes dragged onto a second monitor.
I dragged them all back and docked them to the sides of the main program window and turned off those palettes he wasn't using.
Restarted the machine and it all seemed to be good again.

I’ve done all kinds of tests so far as this is affecting me and some of our clients. WE settings, video card settings, Windows 10 Visual Display settings. None of them made a difference.

The common theme seems to be nVidia so I suspect it may have to do with their drivers. It may be worth rolling them back pre-June 2017? Still waiting to hear back from GS on it.

If it is caused by NVidia, does it only apply to PC's? Apple uses a different video card, don't they?

Make sure that Nvidia GeForce Experience program is disabled or deleted if that is installed and running.

How do I delete or disable the GeForce Experience program? Have I even got it?
