The performance of the PBXGK-BB PowerStorm 4D10T ELSA GLoria Synergy 
was low, and the early drivers didn't help.  Text scroll was really bad.

For VAX, AFAIK, all of the graphics controllers used in later-series 
VAX boxes were descendants of the GPX and SPX graphics.

By current standards, the "top-end" Radeon 7500 is glacial, but then 
it's also a PCI widget.  (Yes, the AGP variant reportedly sometimes 
works in a couple of the OpenVMS boxes that feature AGP slots, but 
AFAIK that is not supported.)

HP has a new graphics controller (an unspecified-model ATI FireMV) on 
the roadmap for the rx2800, FWIW.
