Oculus Crescent Bay resolution is higher than DK2. Refresh rate is higher at 90 fps vs. 75 fps. The device is lighter and more comfortable than previous generations.
Crescent Bay however is more than just a nicer Head Mounted Display (HMD). Crescent Bay provides 3D positional audio. You may think you've “heard” this before with positional audio from companies such as Creative Labs with their CMSS-3D technology in cards such as the X-Fi. Oculus 3D positional audio however is different. During the Crescent Bay demo I took special note of how it worked. The audio gives you a clear idea of where and how far the sound is away from you. As you lean into something producing the sound it gets a little louder. It no longer sounds like an approximation of 3D audio as it does with Creative CMSS-3D.
With the addition of precise head tracking that VR devices provide. It providers audio developers with a greater set of tools to provide the listener a greater sense of VR immersion.
Oculus had previously licensed technology from Real Space 3D Audio and integrated it into their SDK.
Onto the really good news. Oculus have disclosed that we will not need to wait for the Consumer Version (CV1) to try 3D audio for ourselves. Oculus will release a version of the SDK for the DK2 prior to the CV1 launch.
So make sure you have a nice set of headphones on your desk.
Want to try 3D Positional Audio now? You can in the latest TECHNOLUST: A Way Out demo that I reviewed last month. You can also try some Real Space 3D Audio Demos from their own site.
