Windows 10 1809 has resolved almost all of the performance issues I was seeing with PR 2019. After upgrading to 1809 I reinstalled the same graphics driver I was using with 1803 because the upgrade changed my driver to a built in Windows driver.
- Ryzen 5 1600 CPU
- 16GB RAM
- 512GB NVME SSD
- Radeon RX 480 8GB GPU
Windows 10 1803:
- poor performance with masking brushes (lagging/stuttering)
- Cataloging issues
- Database would take about 10 seconds to close after closing PR 2019.2 and I don't even use the cataloging feature.
- Lag when selecting photos
Windows 10 1809:
- Masking brush performance is greatly improved. It will still lag after a lot of cumulative brush stokes, but it takes far more before performance starts to degrade.
- Database shutdown window doesn't even appear anymore.
- Will test cataloging this weekend
Still see a little lag when changing from photo to photo, but it's about a 50% improvement in speed.
Something else I noticed after the upgrade was a difference in RAM usage. While on 1803, RAM usage was always below 7GB. After the upgrade I found PR would use over 10GB of RAM when working on photos with a lot of masking brush edits and I believe it would have used more if it were available because my system as a whole was using about 92-95% of my available memory. This may be why I started to see the performance decrease. So I ordered another 16GB stick to bump my system to 32GB. I've been wanting to do this for a while, but didn't feel PR would take advantage of it until now.
I also had issues with PR freezing or crashing occasionally on 1803, but so far I have not had any with 1809, but I've only been on 1809 for a day. I will continue testing to see what else I notice, but so far I would say a lot of my issues were because of Windows, not PR.
