I must be strange, it seemed fine to me at that frame rate. It's not the fastest thing I've ever used but certainly much faster than the Pi. I opened Kodi, wtf is that name anyway? and it locked up the whole machine. Kodi is still beta right? That could be some of it. I've moved to Plex, at least it's not a stupid kids toy name or a fucking dog or something.
Anyway, for the price of a Pi it's decent, but not earth shattering.
I think it was like that at one point. But it seems like they now do a major release with a couple of point releases. Currently on 13.2 with the betas/RCs being for 14.
