That doesn't mean offscreen bitmaps are there and actually works. Highwire for example requires this cookie + vq_scrninfo(), but doesn't use offscreen bitmaps at all.

Offscreen bitmaps in fVDI are either broken or bogus. It's possible that there was some experimental implementation of it 10 years ago, but fVDI needs a lot of work in this area if it is to become a useful alternative to NVDI. I tried opening offscreen bitmaps on fVDI, and it fails. That was about a year ago though. Might be driver specific, but then it should create bitmaps in fastram instead - which it doesn't.
