Oh damn, I forgot something crucial to get the most performance out of that sucker.
(1)- Go to laptopvideo2go.com
(2)- Get the latest .inf enhancer/patch file to match the driver set you want
(3)- Get some current/recent Nvidia drivers
For whatever reason, most OEM notebooks with nvidia video have really old drivers, and just trying to install the latest from Nvidia won't work (it says something like no supported hardware detected IIRC). Anyway, the .inf patch unlocks the driver to work on notebook drivers.
Going from old drivers to current drivers can fix graphics glitches and increase performance in many games. You could also try a *very* mild overclock, so long as you keep an eye on the temps. I'd try to keep it 5-10% at most over stock, notebook cooling usually isn't the best.
