PP2019 laggy, unworkable on top-of-line clean computer (not playback, though)

[RyanPatch]

I own a Dell XPS 7590 - their top-of line laptop.

8-Core, i9 CPU, 32gb RAM, GTX 1650 4GB GDDR5.  I just acquired it for paternity leave, and it's clean.  I am editing off of an NVMe SSD attached with a USB 3.1 interface, that gets ~900 MBps read and write speed.  All drivers are updated. 28gb of ram allocated to Adobe apps.

Premiere on this computer goes slower, is laggier, and crashes WAY more often than my 4-year old i7, GTX 980 Desktop System.

I particularly have trouble when relinking files, when changing workspaces, or when toggling back to Premiere from ANY other app.  I have lesser but still noticeable lag when doing things like opening a new timeline. Actual playback is very smooth and rendering works great.

3-10 minute hangs when trying to open a folder for a re-link.  5+ minute hangs on workspace selection, and 30+ seconds to become responsive upon toggling.

This happens regardless of media type, and on both new, fresh projects as well as established, 5-10mb projects.  It even takes several seconds to re-draw the workspace when changing workspaces in a NEW project with nothing imported.

I am at my wit's end.  I need this software to work.

My first thought is to disable the Intel Display Adapter. Try from the Bios. If not, you may be able to do it from Device Manager.

This does not work - no BIOS setting, and when done from Device Manager, it makes everything run way worse, even playback.

Do a search of the threads. There's info on the Intel drivers, and making sure you have the Nvidia being used in PP. You might look in this folder for gpusniffer.exe, run that from a command prompt

C:\Program Files\Adobe\Adobe Premiere Pro 2020

Intels top of the line performance processors don't come with built in video, partly for this reason.
