Comment (by eero-t):

 Since I last commented this, there have been some noticeable changes to
 the performance in different APIs, but unfortunately they're all over, and
 too device / platform specific, for me to be able to do any conclusions of
 them.

 Btw. #7943 is now mainly about the 2x QSV memory usage, so I wonder
 whether gpucopy support should have another ticket?
