    Hi, I wonder is there any way to force intel gpu to work along with nvidia gpu at the same time?

    Not how Optimus works.
    AMD based systems with a a AMD Llano / Trinity cpu and some AMD Radeon HD gpu models can do Hybrid Crossfire and i think thats what you where aiming at with the question.

    So I guess, that's a negative? What a pity, I thought that there was some way to get intel gpu out of an idle mode and force it to join the big brother. That would definitely give a substantial performance boost in games.

    Theres something called lucid ... it works with intel sandy bridge video cards and a dedicated card..not sure if it works with optimus.
    Its really good for video encoding but not great/is worse for gaming.

    And what if I bought some external graphics card? Would I be able to make it work together with 540GTm or would I still have to choose between the two, or I guess the three?

    No. You can't get it to work. Even if somehow you could, the performance would be garbage without nvidias support in providing asymmetrical SLI profiles.

    Right. The answer is NO YOU CAN'T.

    Even with Asymmetrical Crosfire on the Llano notebooks, the difference in performance was only about 10-20% FPS improvement and it causes microstutters like crazy in most games WITH proper driver support. And that's an IGP and dGPU from the same manufacturer. Imagine from two different manufacturers.

    It works with Optimus system, however there'll be a big logo floating around whenever the dGPU is in use. Because Clevo boards are not registered in their support line, so it became trial mode.
