    Ok slight annoying prob. I have an alienware mx17 ive ordered recently. basically it has 4 gigs of ram with the dual 260s n such. Up until npw, it played games like crysis on high settings with no problems.But now when i unplugged my laptop then turned it on at my friends house for a lan. But now when at home and plugged in, but now the performance seems to have taken a hit? crysis on the exact same settings previously, now plays like a slide show. What could the problem be? i went on the alienware program and everything is running on max performance

    You're most likely running it on the 9400M integrated chip designed for longer battery life. I think you hit Fn+F7 (can't remember exactly which F-key it is, should say I/D GFX on it) and it'll prompt you to restart. Do so and it should be back to normal.

    My guess is that your are now using the integrated graphic chip and not your 260 SLI cards. Are you in Hybrid SLI?

    You can go into your bios and and under graphics settings and select disabled/disabled as this will make the machine only run on the 260s until the next time you unplug it .

    When you boot the computer when on battery it will start running on the integrated chip.

    To go back to the 260's, go into the bios(press F2 when booting the computer when the Alien head is on the screen) go into the middle tab, go under graphics settings, and either set them both to disabled, or both to enabled and set the Nvidia hybrid SLI to boost performance

    If he is on the 186.82 driver I have also noticed this. The only real bug I can find at present with it. I ended up having to hit F7 once I was back into the OS on AC Power. Personally I believe it should be able to autodetect your power source and adjust correctly (unless you have chosen to disable the mGPU in the BIOS in which case you shouldn't even see the NVIDIA chevrons icon in the tasktray).

    AC Power = Discrete + mGPU (Boost Performance)
    DC Power = mGPU only (Save Power)

    Just a thought.
