performance issues, dealing with stealth mode

Hey i have a m15x with an i7, gtx 460m , 8gb ram, playing BF3 i was noticing after I played for a short time I would get a frame rate drop slowly throughout my play time. Now I'm starting to play League of Legends and it happens with it too. weird thing is if i toggle the stealth mode on and off it usually kicks it back to normal operating for a short time, then it goes back.

I was running cpu-z while playing bf3 and it was showing my processor shows it is running at like 530mhz while i was playing bf3 single player, seems like it should be going quite faster i would think.

anyone else have these issues? i have the latest drivers

 

update i was just watching cpu-z and i was just doing nothing ont he computer and it was going around 750-1100 mhz, the second i started up the game and loaded the level it went down to 532mhz

 

Are you using the latest bios version?

You might want to run ThrottleStop with the log file option checked to find out what's really going on. Some of these laptops use Chipset Clock Modulation which is a method to slow a CPU down to a crawl. If the log file doesn't show both types of clock modulation at 100.0% then that's a problem. ThrottleStop can help with this but your best bet is to update the bios first.
