@Oppo,

Please check the thread posted by yigit, see link below which will bring you directly to the solution.

Just another suggestion to try even though yigit and jamez's advice prolly fixed your problem. You may want to check what programs are running in the background. Things like Norton and other bloatware like them tend to be resource hogs and will cause your system to slow down.

I have already fiddled with battery management and the problem still surfaces.

Also i have nothing running but the games themselves, my CPU usage is nowhere near maxed out,

I am sure that is not the problem.

@Oppo,

Try going into the BIOS of the Y470 and do a BIOS factory reset.

Ok I'll give that a shot.

Do you have the NVIDIA GPU Control Panel software installed?  I noticed that you need to add specific applications to the "Manage 3d Settings" portion of the control panel.  

So open NVIDIA GPU Control Panel -> click "Manage 3D Settings" on the left -> click the "Program Settings" tab on the right.

Next, click "Add" in the "Select a Program to Optimize" area, choose the *.exe for the game.  Then select "High Performance NVIDIA Processor" from the drop-down box below the "Add" dialogue.

You can customize what "High Performance NVIDIA Processor" actually does from the "Global Settings" tab.

Again, it does not seem that you will experience full GPU usage without adjusting this setting.

I reset my BIOS and yes, I have all applicable programs set to "nvidia high performance" in the NVIDIA GPU control pannel.

The problem still exists however.

My theory is that the games I am playing are switching between integrated and dedicated cards, resulting in serious frame rate reductions. This theory is backed by the fact that the dedicated GPU usage spikes downward on consistent intervals, suggesting the program has, for some reason, stopped using it, and has switched to the integrated card.

Is there any fix to this? Has this problem ever been reported or is it a rare occurrence? 
This is only a theory of mine I would like to have it confirmed or denied.

I've been posting with the guys on the Nvidia forums, we believe it to be the work of the optimus technology in the mobile cards, that is, in badly ported games it switches between the integrated and discrete GPU's for no reason. I'll post any updates as I troubleshoot.

Hey I'm having similar issues with my Y470 when playing games such as League of Legends and D3 Beta. Like you said before, I've tried updating my drivers and it didn't fix anything. My fps will randomly drop from 60 to 5 for a few seconds and go back up to 60, during which the sound gets really distorted and at times i hear a beep from my speakers. Please let me know if you find out anything to fix this problem.

D3 Just runs awfully. The 550M should be able to run it at high settings on my native res, but it fails to even run it at a consistent frame rate on low at 800x600. Is it just me or is it my card? It skyrockets to temps about 75-85 deg C and then lags horribly. I have no idea what to do here anymore. Reinstall the game, go to stable driver versions, nothing works ever.
