Heck if I know where this is supposed to be posted, but I figured it might be useful to note for posterity.

Apparently certain onboard Intel graphics chipsets operate very slowly with NTVDM, particularly when switching to full-screen text mode. Someone's made a patch. There's a nice little writeup describing the oversight as well:

I wonder how Microsoft and Intel feel about this guy fixing the problem.

Microsoft is surely indifferent to any further developments with NTVDM. (Well, except for maybe security vulnerabilities, but how many people could there be running still-supported versions of 32-bit Windows?)

The problem with Intel & Microsoft, and especially their combination (Intel HW running Microsoft OS) is that, being big corporations, they are absolutely unable/unwilling/unprepared to deal with technical issues from individual users.

If this issue had been found by internal validation, or raised by a major customer (OEM), e.g., it would probably have been spotted and solved a long time ago. But apparently, not one of these tests NTVDM during their validation.
