Turbo boost/ Speed step not working while gaming

I'm on an MSI GT70-0NE laptop. It has:

Windows 8 Pro
i7-3630QM
GTX 680m
16 GB RAM

I recently downloaded MSI Afterburner so i could monitor my FPS and temperatures since i'm on a laptop, and I noticed that my GPU usage will jump all over the place on just about any game I play. For example:

Borderlands 2
Tomb Raider
Crysis 3

Like I can be ingame, and not move and stare somewhere, and the GPU % will go from 35 to 76 to 45 to 91.

The results of course are FPS that are all over the place. It's pretty frustrating trying to game with all the drops.

I've tried installing different drivers (WHQL 314.22/ 320.18 and the latest beta drivers 320.49). I've even tried installing the msi unlocked BIOS to over-clock it.

And the weird thing is, when i run a benchmark like 3dMark (2013) it will hit 99% and stay there through out the benchmark.

The card isn't heating up. It's generally in the 60's when gaming, probably mostly because it's not working hard. But i have the laptop on a cooler and it's getting good air flow.

After doing some more testing, this has to be because of turbo boost/ speed step (which is it now).

Whats happening is, the CPU is constantly throttling down to 1.2 GHz. So it will bounce back and forth between 1.2 GHz and 3.2 GHz. Of course when it throttles down, the GPU gets bottle-necked, and the frames crap out.

I assume this isn't normal, or else gamer's wouldn't be buying Intel CPU's. So something is either causing the CPU to downclock, or something isn't letting it over clock.

I have it on "performance" in power management settings. I don't know what would be causing it to down clock. CPU temps are only 55-65.

I'm guessing there's no way to manually keep it on, that would be too easy.

Anyone have any suggestions

Not sure what kind of CPU options you are given in your laptop, but I would try disabling Speed Step in the BIOS so your CPU wont downclock.

Speed Step only downclocks the CPU when it thinks the load isnt high.

Well, i can turn off speed step, but that apparently also turns off turbo boost. So it will stay at 2.2 GHZ for most of the time (instead of 3.2GHz turbo) but it will STILL downclock to 1.2 GHz.

If it's still downlocking you dont have speed step off. Think about it.
