Stuttering, Small freezes and framerate Issues

[rattlehead]

Exactly what is it that happens with the piano when it stutters? I have a laptop to test with:

Settings - medium
OS: win 7 64bits
GPU: HD 5850m
CPU: i5 2.4CPU m something or such.
RAM: 4 Gb

and I don't get stutter with the piano but perhaps I don't notice it because I am trying to notice it at the wrong spot/time of the event (the big quake? or when it starts to play?).

Your settings are only high? You have not increased SSAO to high and 32x samples or some such? Just want to make 100% certain!

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.

Settings - high
OS: win 7 64bits
GPU: HD 7950 3Gb
CPU: i5 3570k
RAM: 8 Gb
note - nothing is overclocked.

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

Settings - High
Windows 8 -64 bit
GT 640m
i7 3632QM
6 Gb RAM

Before the piano there is a tiny stuttering before the quake and thats all
No, i haven´t change nothing, just high on the launcher
The only problem i see now is the areas where the fps is only around 30/40 even on low settings.
