whether I use the zoom tool or key combo/scroll, zoom in or out takes between about a full second to multiple seconds. makes it very hard to control. this seems to happen regardless of the document complexity. Photoshop and XD zoom well.

this PC got a fresh Windows 10 install a month ago, then Illustrator was installed for the first time. this has been an issue since then.

I've tried GPU Performance preference on and off.
I've uninstalled, cleaned, re-installed Illustrator a few times since then.
I've reset preferences.

Illustrator 23.0.1
Windows 1803 64, Xeon 2 X 2.60 GHz, 256 GB RAM
NVIDIA Quadro P6000
