The removal of the traditional DirectSound 3D Hardware extension API in Windows Vista has flattened the PC 3D audio landscape. This resulted in teething problems for gamers – who lost DirectSound 3D HW positioning, surround sounds, and EAX effects while playing a multitude of existing DirectX game titles in Windows Vista. To circumvent this problem, ASUS has utilized the new DS3D GX gaming audio technology for not only the latest Xonar D2X and U1 products, but also existing Xonar ~ With DS3D GX technology, proprietary API deployment efforts like OpenAL are unnecessary for both game developers and the sound devices. Unlike other competitive solutions, DS3D GX does not require patch installations or additional expense. Users automatically get DS3D GX functions immediately after installing the updated Xonar drivers. |
No "alchemy" that has to do translation for most (but not all games) and forcing there Audigy users to pay (and do internet activation) for this feature. (X-Fi users get this software for free).
