Stuttering, Small freezes and framerate Issues

[jdw5000]

ok with the new update there is almost no stuttering, just a little i the part before the piano.
But in some areas there is a massive fps hit like 60 to 40 maybe.
And i have a system that should run this game at always 60 fps.
But overall is a good improvement.

Same thing happening on my game, no noticeable stutter until the piano.
