    I know that when the laptop is unplugged it undervolts itself or something so games don't run as good as they do when it is plugged in. Is there a way to keep the performance of being plugged in with only the battery? I know the battery won't last too much unplugged but I'd still want to know

    The power draw of the GPU is too much for the battery to provide. Hence, the GPU downclocks significantly, for me, the GPU downclocks almost 75% (from overclocked) when the notebook is unplugged.

    AFAIK, there is no way to get around this. I have tried locking the GPU clocks at the highest performance state but it just crashes due to insufficient power.

    No, there isn't too much you can do about it unfortunately. The laptop power draw is significant enough that the battery just wouldn't cut it. Even if it could, you'd be talking a glorified UPS and getting a handful of minutes out of it at full power. Nvidia doesn't build any way to get around the automatic down clocking into drivers (short of trying a software overclocking utility- not recommended, and it may not even work)

    There was a way by modifying the driver's registry, i've done it before but my graphics card was an old nvidia 8600gt in my xps1530, so the battery could handle the power requirements for about 30 minutes, when it would normally last 2 hours. There is also a way of doing it with ATi cards via the Catalyst control center, but again 30 or less minutes of gaming isnt worth trying to get the thing to work at full clock.

    I could imagine that an nvidia 460m would be too much for your battery, as the guys above said.
