CoreApplication.DisableKinectGpuReservation Property

Disables or enables the NUI system GPU reserve.

Syntax

public:
static property bool DisableKinectGpuReservation {
         bool get ();
         void set (bool value);
}

Property value

Type: bool

Returns true if the NUI system GPU reserve is disabled and false if the reserve is enabled.

Remarks

Titles that do not use NUI Gestures (streams based on depth or IR) can disable the NUI GPU reserve and make use of the 4.5% NUI GPU reserve. To disable the NUI GPU reserve, set the CoreApplication.DisableKinectGpuReservation Property to true:

Windows::ApplicationModel::Core::CoreApplication::DisableKinectGpuReservation = true;

Note It is recommended that titles re-enable NUI gestures when the title is in in-game menus or lobbies (by setting DisableKinectGpuReservation = false) to allow controller pairing and bio-metric sign-in to work.

NUI Interactions for Opt-Out Titles and Snapped Shared Apps

Because an exclusive app can elect to disable the NUI GPU Reserve, there is no guarantee that the shared app would have the available GPU processing resources to receive these Kinect streams. Shared apps do not support NUI depth, skeletal tracking, or IR while they are snapped (although they can continue to leverage them when they are full screen).

Both for exclusive apps that disable the NUI GPU Reserve and all snapped shared apps, the specific behaviors for existing NUI APIs are as follows:

A number of NUI streams are not available:
The KinectSensor::IsAvailable property continues to behave as before (that is, it accurately reflects whether the sensor is plugged in and not disabled in the Settings app).
Streams that are not available will not generate frames:
- *FrameReader::AquireLatestFrame always returns nullptr.
- *FrameReader::FrameArrived events will never fire.
- MultiSourceFrameReader will not generate frames if the app has requested anything more than color and/or audio.
All gesture input, including PointerPoint input, is not supported.
