Quoted from Setsul

[…]
Intel Turbo Boost or similiar things can still mess it up. You should really check the actual clock speed while playing to be sure it´s not this problem. Unless you already found the problem it´s worth a try.

Checked, clock speed while playing is just normal (3725 MHz) http://i.imgur.com/HjjOp.jpg.
