I was about to give up on Paintshop PRo 2019

[eja]

I've been running PSP 2019 on a dell desktop that has 16gig of ram, an SSD drive and a Navida graphics card. I found PSP slow and cumbersome to use compared to Affinity Photo. I was about to give up using PSP and then I decided to load PSP on my lenovo laptop with half as much memory, no SSd drive and no dedicated graphics card. I was so surprised to find that PSP runs better on my laptop than on my desktop. It is actually a pleasure to work with PSP on the laptop compared to the desktop and now I am scratching my head with how to trouble shoot what may be slowing PSP down on my desktop. Does anyone have any suggestions on where to start?

Thanks

Some extensions in system can slow down PSP. There has been lonn discussions here.
