6.9DS3D GX (for Vista Only) and DSP Modes

Xonar D2X is introducing an innovative technology –DirectSound 3D Game Extensions v1.0 (DS3D GX 1.0)- to restore DirectSound 3D Hardware acceleration mode and its subsidiary EAX effects on Windows Vista for 3D games. Unlike some proprietary API like OpenAL, DS3D GX doesn’t require games to support OpenAL API. All existing games compatible with Microsoft DirectX and DirectSound 2D/3D will be supported with DS3D GX technology. Before you start EAX and DS3D HW games, please enable DS3D GX on the Xonar D2X audio center, and disable the function after the games.

Besides the abundant sound effects described above, the Xonar D2X also provides quick Digital Sound Processing modes which are configured for typical applications including Music, Movies, and Games over different output speaker types. In addition, Xonar D2X also offers a Hi-Fi mode for hi-fidelity playback without any effect processing to keep the original audio fidelity. Every time you turn on Hi-Fi mode, Xonar D2X will clear all sound effects. It’s also recommended to use Hi-Fi mode for audio quality tests (using RMAA software or another machine- based measurement). Use the DSP mode button as the quick setup if you don’t wish to know the details of the effect setup. (Note: no sound effects will be applied to high-definition 96KHz/192KHz content.)
