    My Graphic is Geforce 6150
    when i's playing Heroes V with battery, i felt that the game was quite a lag
    but when i put AC power into my laptop the lag is disappear

    I check the CPU performance, it had the same speed between battery and AC Power, 1,6Ghz max and 800Mhz min with RMClock.

    does the graphic card will do better performance when it's plugged into AC adapter ??

    Sorry for my bad english

    Your English is fine. :)

    Yes, the performance is not as good on battery. Check the Nvidia PowerMizer settings - Right-click Desktop, Properties, Settings tab, Advanced button, then go to the Nvidia tab and locate "PowerMizer". There will be settings there for when on battery and when plugged in. Put the sliders all the way to the right.

    The video card downclocks on battery to save power. Note that you will not have as good of battery life if you tell it to use maximum performance on battery.

    This is similar to Intel Speed Step methords, which downclocks the CPU, when running in batttery power. And in fact, all this downclocking does make a difference, as shown by the Super-Pi figures in the hardware section of the forum.
