EngineCreateOptionsCustomDeviceId Property

When set to a non-zero value, then the PhysicalDevice with this DeviceId will be selected as the used device. If the device with this Id does not exist, then a default device will be used (a Warn log message will be written about that). When setting this value, the DeviceSelectionType is automatically set to CustomDeviceId.

public uint CustomDeviceId { get; set; }
