Gundark: you are right the slowdown is not ralated with shader compilation. Is a classical VI desync because if you put the frame limmiter off in my case the fps down to 90 fps, if that was a shader compiler problem the down a lot for example you can test Mario Kart Start Race shader issue with frame limiter off you have a big slowdown, but Just dance is other issue not related
Edit: Strange dont seem to be a VI desync, I neve see that in the past the VPS slowdown in constant way, if you have frame limmiter off, 80, auto etc you always we have a 15 vps aprox slowdown :S
