Enhancement: enable high refresh rates (frame rates?) in guests

Description

From what I understand, VirtualBox caps the refresh rate (or frame rate - not sure which terminology is correct) of the guest's display to 60Hz, and attempting to force any refresh rates higher than that is pointless.

This results in a very noticeable drop in smoothness when using the guest operating system on a host machine with a high refresh rate.

Simple tasks such as dragging or resizing GUI windows are noticeably laggier than on the host OS.

For example, I'm using a Windows host on a monitor which supports 200Hz. The host OS feels far, far more responsive and enjoyable to use than any of the guest machines.

I am not a VirtualBox developer so I don't know the technical details, but it would be great if it was possible to allow VirtualBox guests to output higher refresh/frame rates, up to and including the refresh rate set on the host OS.
