    You know I just realised.
    Are there any Crossfire laptops out there? I really want to know if Nvidia is just pulling our legs on this one,having the only sollution of 2 cards in one laptop and allowing the stuttering to go on due to lack of competition...

    I think people are targeting NVDIA too soon. Using a tool once posted by Shyster that messures DPC, my system would cross the red line too often for my test.

    I'll add the following, and I don't know if it is related or not but the effect is somewhat similar. At work, when I go out for lunch my laptop stays on. When I come back, dragging windows and some other 3d effects get the micro stutter and the laptop is slow.

    1) I measure the CPU speed and everything is fine
    2) Do the same for the GPU ... same thing.

    I need to reboot the system in order to come back to normal.

    By the way, Vista does not go to hibernate, sleep or any other mode you might think of. I simply don't use power savings most of the time fot testing purposes.

    By the way here is the link to the tool I mentioned. A DPC-latency utility, DPC Latency Checker by Thesycon, which can be downloaded from here: http://www.thesycon.de/deu/latency_check.shtml

    The actual d/l link is: http://www.thesycon.de/dpclat/dpclat.exe

    ARGH, can you test on yours and chek if you get any warnings with this tool?

    yea i got some kind of warning messege with that program. i am not really concerned, though. the system is running just fine with the exception of the micro stutter which i now firmly believe is the currenty nature of multi-gpu's on all platforms so i am not blaming the laptop design for this.

    Mheh, more recently I can`t put the computer in standby, it will resume to a black screen.
    So I take it some of you have it also, since I initially heard about it on you SLI system users...
    Darn it.
    About the stutter,Trance, you have 5400rpm drives. Maybe switching to faster ones would help...
