Both joker2000 and myself have had an issue with KB4601319 impacting performance (maybe in my case KB4601050 too). If you're a Windows 10 user its worth checking if you've received the KB4601319 patch and if it coincided with the loss in performance.

Im running into this too. It has affected all versions of Poser that I have...except for Poser Pro 7 (ironically). I'm also on Windows 10 and removed every update that I could, but it didn't help. I do not see any of the 3 updates on my system that you mentioned above (KB4601319, KB4601050, KB4601319), unless its one of these that show no number:

Uninstalled with no affect:

Microsoft  Visual C++ 2010 x64 Redistributable (KB2565063)
Microsoft  Visual C++ 2010 x86 Redistributable (KB2565063)
Feature Update to Windows 10 21H1 viea Enablement Package (KB5000736)
Update for (KB2504637) - MS .NET Framework 4 Multi-Trageting Pack
Update for Microsoft Windows (KB4584229)
Update for Microsoft Windows (KB5003254)
Update for Microsoft Windows (KB4601554)

Not Uninstall (Option is disabled/hidden):

Security Update for Adoble Acrobat X (10.1.1)
Security Update for Adobe Flash Player
Security Update for Microsoft Windows (KB4566785)
Security Update for Microsoft Windows (KB4570334)
Security Update for Microsoft Windows (KB4593175)
Security Update for Microsoft Windows (KB5003173) (allowed, but fails with error)
Servicing Stack 10.0.19041.985
Update for Microsfot Windows (KB4565627)
Update for Removal of Adobe Flash Player

Hope it gets fixed soon. On Windows 7 I am not having any slow down issues.
