35 ASUS Xonar Essence STX
6.8 DS3D GX and DSP Modes
Xonar Essence STX 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, enable DS3D GX on the Xonar Audio Center, and
disable the function after the games.
Supports latest DS3D GX 2.0 for gaming on Vista & XP
DS3D GX 2.0 not only revives EAX and DirectSound HW effects, but also
allows you to run EAX HD 5.0 games on both XP and Vista. It provides the best
compatibility with existing DirectX games. GX2.0 also adds innovative VocalFX
voice effects for existing EAX games or VOIP applications.
Besides the abundant sound effects described above, the Xonar Essence STX
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 Essence STX 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 HDAV 1 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.)
