[Techage]Creative EAX vs ASUS DS3D GX 2.0

post #1 of 4

When we first reviewed ASUS' Xonar D2 sound card in September of last year, 'impressed' didn't begin to describe our initial reaction - quite simply put, it rocked our faces off. Several other Techgage authors quickly picked up cards of their own, and were similarly stunned by the competency, clarity, and fidelity. We were sure that Creative's X-Fi cards had finally met their match, but one gripe that we repeatedly heard from our readers was lack of support for Creative's EAX versions 3.0 and above.
EAX, now in version 5.0, is a proprietary Creative Labs technology, but versions 1.0 and 2.0 of the specification were made freely available for use by other manufacturers, a practice that ceased with version 3.0. It was a clever scheme - versions 1 and 2 of EAX were hugely popular, and gamers hoping to take advantage of the technology's newest iteration would have to choose Creative hardware exclusively.
[...]
The centerpiece of EAX is hardware-based signal processing, controlled directly through the software itself, which is why we were surprised to learn that ASUS had released a new driver revision for their Xonar cards, enabling "EAX 5.0 Support". We initially assumed that ASUS' driver wizards had come up with a way to mimic the Creative X-Fi's onboard DSP through the driver software itself, in the same way that Dolby and DTS processing are handled.
In a sense, we were correct. To finagle the functionality of Creative's EAX 5.0 from the ASUS AV200 (D2, D2X) and AV100 (DX) audio processors (better known as the C-Media CMI8788 OxygenHD chipset), which rely upon software-based DSP, ASUS reworked the DS3D GX extension set to provide all the functionality of Creative's EAX Advanced HD 5.0 through the DirectSound engine itself - in software. That means 128-voice 3D positional audio and environmental reverberation. ASUS admits that this isn't true 'EAX' - rather an emulation of the functionality of EAX 5.0 through the software driver.

Nice! I will have to get one of those as my next card. More power to them for emulating eax5.

What I would like to add is that this test was as close to pro-Creative as possible: XP and the games were suggested by Creative themselves.

However, the reviewer was honest about it and he shows us a review which is representative only for such a configuration. If a test on Vista x64 and other games, I don't know, but I sure would like to.
