To touch on gaming performance, we chose two games that draw moderately on system resources, Half-Life 2 Episode 2 and Enemy Territory: Quake Wars. We then ran a pre-recorded demo of each at a resolution of 1280x800. The resulting performance achieved is indicated in frames per second in the graph below, and for comparison with machines that are able to play at higher resolutions with larger screens, we'll provide you with a link to our chart from the Asus G51J review.
As the Windows Experience score hints at, the Tecra A11 isn't the best at gaming performance. The machine can handle Half-Life 2 Episode 2 and Enemy Territory: Quake Wars, but its performance doesn't begin to compare with a more serious gaming rig.
