VM running slow after upgrading host from Win10 1809 to 1909

[yaronkl67]

I use  VMware Workstation version 16 .1.0 build 17198959, running on  Windows 10 . It has been working very well on   Windows 10 build 1809.

My computer was upgraded to  build 1909. Now all the  VM's are running slow: keystrokes a re sluggish,   disk operations take much longer, everything is like in slo w motion. 

The VM's are   Windows 10, 8,   Windows 2016 server. All   slow now.

Is this a known problem? Is there a fix?   

Thank  you.

Problem solved by disabling   3D   graphics acceleration (VM Hardware | Display | 3D Graphics | Accelerate   3D    graphics).
