    Why is it easier and/or better than 3dmark11?

    possibly because 3dmark11 runs at low enough framerate to not be affected by whatever factors bottleneck performance on games / applications that run at higher fps.

    Quick question, how is it you were able to use the Sandy Bridge processor of your HM with the 7970M? It was my understanding that the 7970M with a compatible vBIOS for the HM motherboards haven't been released to the public yet.

    So you installed the 2920XM into the P150EM and used that with the 7970M?

    Okay, gotcha, was curious as to your configuration because I hadn't seen it earlier.

    So with the EM models, the dGPU interacts with the display and the rest of the system chipset differently than that of the Alienware machines, even though they are both HM77, yes? Since Enduro can be disabled on the Alienware machines, that means the dGPU and iGPU both output to the display independently of one another, whereas apparently this isn't the case for the EM series, as the dGPU runs through the iGPU to the display.

    Correct me if I'm wrong here, just trying to put together things from what I've read across different threads. In any case, if we aren't seeing the same problems on HM series machines with the 7970M, that would eliminate any possibility other than an issue with how the dGPU interacts with the HM77 chipset in Clevo machines. If so then Enduro really has nothing to do with this, nor will software remedy the issue. This would be a design flaw in the way the hardware is managed, wouldn't it?

    Again just speculating, I'm not entirely sure how these components interact with one another.

    time will tell, at the moment I am hoping this can be resolved with some drivers or bios updates.

    In alienware the display lines are connected each to a MUX. That mux is then connected to IGP and dGPU and at boot the bios tells the MUX which way to transmit display data. This is only set at boot and can't be changed part way through which is why switching requires a reboot.

    In the sager the display lines will be hard wired to the IGP.
