frame rate drops while playing games on sony vaio pro (HD 4400)

Hello, 

 

While playing games, every 5 min I get this significant frame rate drops during 15 sec. 

 

I think its main processor or graphics processor which is reducing peroformance. Ive read that there is something like speed step. 

 

Could you help me turn of this performance reduction option. 

 

BTW. I have sony vaio pro with hd 4400.

 

Thank you.
