This interface adds some memory residency methods, for budgeting and reserving physical memory.
Inheritance
The IDXGIAdapter3 interface inherits from IDXGIAdapter2. IDXGIAdapter3 also has these types of members:
Methods
The IDXGIAdapter3 interface has these methods.
| IDXGIAdapter3::QueryVideoMemoryInfo This method informs the process of the current budget and process usage. |
| IDXGIAdapter3::RegisterHardwareContentProtectionTeardownStatusEvent Registers to receive notification of hardware content protection teardown events. |
| IDXGIAdapter3::RegisterVideoMemoryBudgetChangeNotificationEvent This method establishes a correlation between a CPU synchronization object and the budget change event. |
| IDXGIAdapter3::SetVideoMemoryReservation This method sends the minimum required physical memory for an application, to the OS. |
| IDXGIAdapter3::UnregisterHardwareContentProtectionTeardownStatus Unregisters an event to stop it from receiving notification of hardware content protection teardown events. |
| IDXGIAdapter3::UnregisterVideoMemoryBudgetChangeNotification This method stops notifying a CPU synchronization object whenever a budget change occurs. An application may switch back to polling the information regularly. |
Remarks
For more details, refer to the Residency section of the D3D12 documentation.
