If you let it run with Basic theme and few rounds you will spot i guess that only first round there is unusual maybe 2-3 times 1-2 sec stutters, then second time and later it is stutter free.
Andy, you have behavior like that (more or less those seconds for stuter) if PIPE_USAGE_STREAM is reverted, right?
The Bad was with vanilla mesa (couple of days old)
The good was that + the patch in Comment 19
I asked is Valley play the same with your good case here and with using Basic theme in Windows :). That is the case for me, and average fps is around 80% in comparasion.
I looked again at Unreal Reflections - there is a difference but it's only right at the start, both have a couple of stutters and they are longer with vanilla then the rest is OK in both cases.
Those Unreal 4 Engine linux demos are slide show fest on Kabini, so i can't recognize if there is stutter between two frames :D. Iguess those simply needs at least 10X+ more powerfull GPU then i have.
