I don't think there is such a thing as a throttle free nvidia laptop GPU. I mean, I would hope not.

Maybe this will be useful: http://www.nvidia.com/object/nvidia-system-tools-6.08-driver.html
I can't remember anymore if it allows you to underclock as well but if it does, you can use it to prevent overheating, or at least delay it. Maybe this way you can have consistent performance for a longer time until thermal throttling kicks in.

HLSL is difficult to configure and there are different ways to achieve the same final look. Some settings are major GPU burners, others not so much. Careful with the prescale value for example, don't set it higher than 2 or 3, especially on later games that run at higher resolutions.
If you give it some time you could probably achieve a look that you are happy with using settings that put less stress on your GPU.
I'm still not done tweaking mine. I have no idea what most of the parameters even mean. I'd have to study CRT technology for a few years at least. Until then, as far as I'm concerned, "Front Porch" is a place where you might sit and enjoy a cold beer.
