First, the Turok 2 demo was used to measure frame rate using the built-in Tmark frame rate counter. All default settings were used, and the resolution was set to 800x600 resolution. Again, resolution was set to 800x600 and all default options were used, except that sound quality was set to high. Finally, I ran Ziff-Davis' Audio WinBench 99 Version 1.0 to measure CPU utilization during sound playback using DirectSound and DirectSound3D. All tests were run a minimum of 3 times and the results averaged, except for the Quake 2 tests, in which the tests were run until 3 consecutive runs generated frame rate results that were within 0.1 frames per second of each other.
