Which menus are these?
We have been unable to reproduce any menus in Office animating as windows.
End of Neil's quote
I'm sorry to have misled you, Neil. Office2010 technically doesn't have 'menus'. I should have said 'dialogs' - FileOpen, FileClose, FileSaveAs, OpenRecentFile; they all behave as windows (I assume they should) & use the Open & Close animations. I use a 1600x900 display with right-side Taskbar and have those dialogs set as large as I can. The Open & Close animations are choppy enough on my rig, particularly with large windows, to be a distraction so I've abandoned using them. The Minimize & Restore animations, on the other hand, are smooth and I still use them. The difference in quality between Open/Close animations & Minimize/Restore animations is significant on my rig for some reason. It's Intel graphics, of course.
I've seen an issue with WindowFX's own UI, BTW - the window opens with a lot of white blocks which fill in one at a time over a period of half a second or so - which I thought at first was due to the WFX animation, but it happens with the Windows default animation, too.
