Hmmm, I just tested a few songs and did not see a delay.
 

you may experience the same i was gotting ... 5FPS for skin 30FPS for video or 15FPS for both depending on build and GPU
latest early builds b5978 and b5980 fixed this (at least for me)
some new settings parameters may help : safeVideoDecode and useLowPowerGPU

safeVideoDecode will not help to make things faster. it's intended to make things a bit slower but more stable, in case your videocard has not a lot of memory and stability issues.

useLowPowerGPU on the other hand, will indeed make video decoding faster if you set it to NO (and if you have a laptop with dual video-cards), at the expense of making stem decoding a bit slower.
 

I agree it shouldn't but
...In fact it seems safeVideoDecode helps to make things faster with some drivers maybe a side effect of inhibiting some software emulated functionalities
and (with intel+nvidia combo) setting useLowPowerGPU make use of intel GPU whitch may be faster maybe due to the nvidia drivers
before these options exist, disabling "accelerated" decoding and/or disabling "fast" GPU was accelerating thing already
that's something like desactivate dxva or use default drivers making things faster
