Hardware-Accelerated Voice Chat
As we mentioned, the Killer Xeno Pro has the ability to offload audio processing on its audio chip and its NPU, thus removing the load from the CPU. To use this feature, the microphone must be plugged into the Killer Xeno Pro and the mic channel must be passed through to the computer's line-in. This can be done with the supplied internal or external audio cables.
Does it work? Yes, the included Xeno Chat application was able to work using Mumble, which is an open source voice chat software. The feature will be more impressive when Teamspeak 2 is supported (as Bigfoot Networks promises it will be on its Web site), since Teamspeak 2 is a much more popular option.
Having said that, even the software version of Mumble showed 0% CPU usage on our test system, so we have to wonder how much of a benefit the hardware-accelerated chat feature will provide.
In any case, let's move on to our tests of the Killer Xeno Pro's core functionality during game play.
