After using Visualize Pro 2017 SP4 for an arbitrary amount of time, could be 5min or 50, my PC will drop from 50+ frames per second to less than 5 FPS in the view port. Any renderings started at this point understandably have the same slow FPS issue. The only solution I've found is to Save and Restart Visualize. This rarely happened on 2016. This is happening on both of our machines that run Visualize.
Are other users having this issue? Is this a known issue that will be addressed in a future service pack?
I have had a roughly similar experience with SP4 Standard. However, FPS in my case drops from 50+ FPS to 3 FPS when I switch from Hi Quality Render to Med Quality Render. Sometimes it will stay locked at 3 FPS, and other times only for 5 minutes or so, depending on the complexity of the model.
