Yes, this is certainly an issue. A player using hardware acceleration
will outperform a player that doesn't. You won't be able to do things
like overlay HTML over the plugin area, perform effects and
transformations, copy the image of the video frame to canvas, etc with
the plugin as a result.

Can you provide details of the specs of the computer, operating
system, and the page that you see these issues so I can test and fix
any issues?
