from what i understand the way AMD has it is that they dont produce every other frame its more like every third or forth frame so if that is how it would work it would not slow the process down but that is of course how they do it and if that would work. but hd 3000 isnt terrible like you say. it can play crysis 2 at 15 fps which to me isnt that bad for what the intel igp's used to be.
15 FPS is virtually unplayable, especially since actual FPS will drop well below that at times. 30 is absolute minimum for FPS playability.

do you know about the new AMD APU's and how they can crossfire with the dedicated gpu? that is what i am talking about. i dont think you guys know what i am talking about as you keep referencing desktop parts. this is a laptop and hd 3000 graphics are not too bad if you could sli them with my nvidia card. and maybe have it render every 3rd frame like how amd does it.
AMD's system works because AMD makes BOTH the APU and the discrete GPU, and has designed them specifically to work with one another. And they do have to be performance-matched to an extent (2:1 discrete:APU performance ratio, otherwise there's no real benefit and it ends up causing more severe and annoying screen stuttering). Intel and Nvidia have not done this for Intel graphics and Nvidia GPUs. Also, prior to AMD's A-series APUs, all notable attempts at linking different-tiered graphics cards were pretty much failures.
The reason people thought you were talking about desktop parts was because it sounded like you were intending to add a discrete Nvidia GPU to an existing integrated Intel desktop setup - something you just cannot do to a laptop. By the sounds of it, though, what you have is an Intel-powered laptop that has the Nvidia GPU already built in from the factory. Laptop hardware is locked down hard, as is pretty much anything else you'd get from a system builder like Dell. You can swap some bits and pieces out, but you can't do much to change the way they function overall.
So is it possible to hybrid-link the absolutely horrid Intel HD3000 graphics to a discrete Nvidia card? Given enough time and funding, a large team of professional R&D specialists could probably work something out. Is there an existing workaround? Nope. It's like trying to do a three-legged race with a deaf and blind paraplegic. There's just no real way for the two to communicate and work together.
