How to keep laptop nvidia gfx at full power all the time?

I had this problem with Vista 64 and Win 7 x64. Laptop: Asus M70vm. Core2Duo 2.53ghz, 4gb ram.

Graphics: Geforce 9600M GS, 128bit, G96 512 DDR2.

This happens in everything from moving windows around the screen to scrolling in Firefox.

The worst offender is when i'm animating in Maya (uses OGL) and i'm manipulating the viewport...for 2 or 3 seconds, it will go at 10fps, then jump to 60fps. I let it sit for a few seconds, then back to choppies again.

Another simple example is if I am moving a window around, it's choppy....i shake it for a few seconds, then the motion is smooth as warm butter.

Here's what I think is happening: Nvidia power settings aren't enabling 100% power in my GFX card all the time when I'm in windows...once it detects that it needs more juice, it switches to high power mode- only problem, is that it isn't seamless. I'm so tired of dealing wit this, it makes everything feel sluggish.

Does anyone know how to fix this? I don't see anything in the control pannel. I recall trying to use some app from nvidia when i had Vista, but it would BSOD hardcore when I opened it. Thanks in advance!

EDIT: well, i think all i need to do is disable powermizer...however, whenever i select the "performance" tab in the Nivida control pannel - it does a hard BSOD - nvock64 or something like that is the culprit. Any ideas how to disable powermizer via command prompt or something similar?
 
eerp. I think i found the solution: change the value of "PerfLevelSRC" in regedit from 3333 to 3322. this disables powermizer when on AC power. the 2222 value disabled powermizer completely (including on battery mode). I haven't tested this out yet...but it seems to be my solution.
 
be careful with that, esp on a laptop you could end up with very early heat death if the power optimizing feature on your vid card is disabled.
 
I've found that if I switch my battery plan to "Performance", it clears up a lot of the stuttering.
