E1505 + ATI Mobility Radeon X1300 + Good trick

I do not know if everyone already knows this but here is what I found out about this combo..

I was playing EA Sports Cricket 2007 and FIFA 2007 on E1505 with 1GB RAM and X1300 video adapter. The games were going real slow (slowmo!) even I set everything to minimum.

But, then just to give it a try, I plugged in the battery charger and it brought life!!! The games are now running fast and furious and without any graphical glitches. My details settings are 2x antialiasing, 1024x768 resolution and HIGH as details setting.

So I think the battery alone is not able to pump enough energy into the graphic adapter here. If you supply AC power directly to it, it is performing very well indeed.

 

Thats what happens on most notebooks with dedicated graphics cards. The card will automatically clock down to save on power. Without that, it would seriously decrease in battery run time. When you do want to game, the it is best to be on AC power, so that clocks are all the highestt they can be.

 

An alternative would be to force your computer to the "always on" power scheme. Disabling ATi's powerplay feature and disabling max battery will give the same result. Zero is 100% right that they clock down to save battery at the expense of gaming performance. Usually people don't game on battery so it's a good way to save some juice. Gaming on battery is probably the fastest way to drain it, so be careful.

 

In the Catalyst Control Panel, find a setting for PowerPlay and you can set it to max performance when on battery. However, this will decrease your battery life.

 

Oh..so I was the only one who did not know this
