I would have more diligent had I known there was going to be a playback improvement :-P

Are any of the more involved Dev's other than JYA paying attention to
this? (this is a callout for them to answer).

It's looking like this may be a major issue that many users, with
varying levels of hardware, are experiencing. I think it may be time
to  create a ticket for this issue, but it would be nice to have a dev
that can work with us in figuring out what's going on, and how exactly
to create a ticket that will lead to some debugging help from the
dev's for the users experiencing the problem to use to troubleshoot.

the other end of all this is that it may be an issue that some of the
further tweaking that's been done for the next release has resolved
already. I'm wondering if anyone running off the latest git is
experiencing?
