Direct Known Subclasses:

VkPhysicalDeviceGroupPropertiesKHR
```
public class VkPhysicalDeviceGroupProperties
extends Struct
implements NativeResource
```
Structure specifying physical device group properties.
Valid Usage (Implicit)
- sType must be STRUCTURE_TYPE_PHYSICAL_DEVICE_GROUP_PROPERTIES
- pNext must be NULL
See Also

EnumeratePhysicalDeviceGroups, EnumeratePhysicalDeviceGroupsKHR

Member documentation
- sType – the type of this structure.
- pNext – NULL or a pointer to an extension-specific structure.
- physicalDeviceCount – the number of physical devices in the group.
- physicalDevices[VK_MAX_DEVICE_GROUP_SIZE] – an array of physical device handles representing all physical devices in the group. The first physicalDeviceCount elements of the array will be valid.
- subsetAllocation – specifies whether logical devices created from the group support allocating device memory on a subset of devices, via the deviceMask member of the VkMemoryAllocateFlagsInfo. If this is FALSE, then all device memory allocations are made across all physical devices in the group. If physicalDeviceCount is 1, then subsetAllocation must be FALSE.
