    Hello all,

    Just got my Dell XPS 15 L502X and I am loving it. I had it configured with the Nvidia Geforce 525M 1GB card with optimus technology. I was curious, if I run a game using the dedicated nvidia card, will the Sandy Bridge integrated graphics work with my dedicated card to improve performance, or is it one or the other?

    Thank you!

    Nope, it's just graphics switching, you're always using just one or the other. I'm no nVidia engineer so if I'm wrong, correct me, but on my optimus system I was required to choose just one or the other when running applications/games.

    There could be an exception when you have a separate display plugged into the HDMI port as that runs off the dedicated GPU only. Not sure if the Intel aids what's on the attached display though. So you'd have one display using the dedicated GPU and the laptop screen itself using the integrated.

    my understanding is that when you're using the nvidia card it does the crunching, or rendering but it always passes through the intel graphics anyways.

    but, take that with a fistful of salt.

    The new AMD Llano chipset does this, but I'm not sure if there is a architecture problem preventing this.

    Yes the final display is done through Optimus. Also that is the reason why Optimus is not compatible with IPS screens (Intel IGP only goes up to 8 bit vs 10 bit IPS screens).

    You need a Sandybridge CPU to use this, but has anyone tried:
