Nvidia themselves are not ready to reveal more information regarding the matter.
VXAO is an unreleased technology which was mistakenly listed in select news releases. We will provide details as soon as they’re available.
VXAO is a Voxel Based Ambient Occlusion technology and is 3 times cheaper than full fledge Global Illumination(GI)
A voxel represents a value on a regular grid in three-dimensional space.
Voxel Based Ambient Occlusion also provides a more stable effect throughout the rendered world.
The results of SSAO are not always correct. For example, when geometry comes near the screen edge or when a far objects is close to a near object in the screen space. Voxel based ambient occlusion has no such problem.
Rise Of The Tomb Raider is shaping up to be quite an interesting title featuring two vendor specific technologies(TressFX from AMD and VXAO from nVidia), however the latter will be a Windows 10 exclusive feature. This is not the first game to use both technologies from both sides of the camp, Grand Theft Auto V also used both PCSS, TXAA from Nvidia and CHS from AMD.
