Thanks for this information Zenith432! :-)
The performance without the 2D acceleration code is not better on a El Capitan host and a High Sierra guest OS. The GUI (Finder & windowserver) of the guest OS is slow as hell!
I uninstalled the VMware Tools newer than 8.5.3 (8.5.10 at the moment ) and reinstalled VMware Tools 8.5.3 in the guest OS. You can download the 8.5.3 VMware Tools "com.vmware.fusion.tools.darwin.zip.tar" from http://softwareupdate.vmware.com/cds/vmw-desktop/fusion/8.5.3/4696910/packages/
The 2D graphics performance is now much better than with newer VMware Tools. Because the VMware Tools 8.5.3 do not depend on newer APIs they require only OS X or macOS 10.5.x or newer. It seems VMware Tools newer than 8.5.3 are optimized for Metal graphics acceleration (upgrade to Fusion 10 or newer without reinstalling the tools), OS X or macOS 10.11.x or newer and VMware Fusion 10.x.x, the first version which supports Metal graphics acceleration on OS X or macOS hosts.
Btw, I use VMware Fusion 8.5.10.
