Next, I tested the notebooks in two modes in Quake 3 :
- 640x480; 16 bit; Vertex Lighting; Low Detail; 16-bit Texture Quality; Bilinear Texture Filter
- 1024x768; 32 bit; Lightmap Lighting; High Detail; 32-bit Texture Quality; Trilinear Texture Filter
The Nvidia GeForce Go 7600 beats its more advanced opponent in this test. The resolutions are low here, so the overall system performance means more than the performance of the graphics card alone.
And again, the Acer Aspire 5654WLMi looks preferable due to the same reasons. Summarizing the graphics tests, I can say that this notebook is quite a gaming machine, even when powered by its battery. Nvidia’s power-saving technologies do not reduce the performance of the graphics core too aggressively when the notebook switches to the battery.
The notebook’s battery life was measured with Battery Eater Pro 2.60. The test was performed at the maximum screen brightness in the following modes:
- Classic (the system bears the maximum and evenly distributed load)
- Reader’s test (the pages are scrolled through each 15 seconds)
- DVD mode (the DVD movie was launched in Battery Eater’s Idle test mode)
The battery of the Sony VAIO VGN-AR11SR may be considered just as a good uninterruptible power supply, but the Acer Aspire 5654WLMi allows you to watch a movie or read from the screen for a good three hours.
Here are the battery discharge diagrams for the different operation modes:
