I pulled my nvidia card and switched back to intel HD graphics onboard, 
it's a G6950 (similar to i3). With the new codebase (I think vaapi is 
running) I get great performance on it, wheras 0.24 was noticeably slow.
It still has exactly the same skipping though.
So no, I don't think the graphics card itself can have anything to do 
with it, it has to be something earlier in the chain.
