    I have run into a bit of a problem while testing games on my laptop. After updating everything, installing the BIOS update and making sure the 6770m was the one running 3d applications, I tried a few demanding games, and noticed the performance was very underwhelming

    -Witcher 2 was barely at 30fps on Low at 1366x768
    -Crysis 2 was at 20 fps on High(Low settings for Crysis 2) at 1600x900
    -Divinity 2 Dragon Knight Saga had atrocious framerate, almost at 25fps after disabling most eye candy at 1600x900
    So I ran a 3DMark06, and got 7325 at 1152x864 (free version wouldn't let me change resolution).
    Pretty bad performance all around.

    So I checked GPU-Z and the voltage was all over the place, as well as the clocks, jumping from 0.9 (clocks being 100/41) to 1.05 (clocks being 1.05/216) and finally, one that almost never seems to show up, 1.1 (clocks being 725/216). This voltage made Crysis 2 run much better (around 40fps on High at 900p), but since it wasn't around for too long, I couldn't try it with other games.

    Now, while all of this happened I was constantly getting a pop up on startup that said "For full performance, connect a higher capacity AC adapter". I investigated round the web a bit, and found out that there's a 90W adapter, instead of the 65W one I have.

    Now my question is, could the AC adapter that came with the computer be insufficient for gaming , and the cause of the unstable voltage and poor performance?

    Specs are
    - MR 6770 - Intel 3000HD
    - i7 2720QM
    - 8GB DDR3 RAM
    don't think they matter much though.

    I would suggest using the 90W adapter, obviously.
    You should see if you can get a refund and swap if a 65w came with your computer.

    Didn't it come with 120w adapter by default? Mine does..

    With an i7 and 6770 the AC adapter could definitely be the issue.. My dv6 with only an i5 and 7690 (rebranded 6770) came with a 120w adapter.

    Got the 90W AC adapter today. That seemed to solve the performance issues. At least for Crysis 2. Runs at 900p, everything but Shading, Post-Processing and Shadows on Extreme (those three on High) at 30+ fps. I'll re run 3DMark06 later and see how it goes. Thanks everyone.
