As the title asked. The version 16.2.0 causes 3D graphics getting much slower comparison with the version 16.0/16.1. The version 16.2 seems just a little faster than version 12.x's for me.
I noticed a new option called "rendering remote client" or something(I don't remember now since I have reversed the vm workstation to version 16.1.2), But I don't believe it was the cause.
BTW is it possible to edit the vmx file for an encrypted virtual-machine manually(if it was encrypted by myself)? After all some option switches can't be set directly with virtual-machine configuration dialog-box.
