DXGI_ERROR_DEVICE_HUNG: The graphics driver stopped responding because of an invalid combination of graphics commands sent by the app.

This method returns one of six possible DXGI error codes indicating the reason for the device removed error: To investigate the cause of device removed errors, call ID3D11Device::GetDeviceRemovedReason before releasing the Direct3D device. It can also indicate a hardware failure or a bug in the graphics driver.

Repeat issues with DXGI device removed errors can indicate that your graphics code is creating invalid conditions during a drawing routine. Remarks Investigating the cause of device removed errors When the HandleDeviceLost method exits, control returns to the rendering loop, which continues on to draw the next frame. Notify the renderers that resources can now be created again. Then, it creates a new swap chain and reinitializes the device-dependent resources controlled by the device management class: // Create the new device and swap chain.Īfter the device and swap chain have been re-established, it notifies app components to reinitialize device-dependent resources: // Create the new device and swap chain. This ensures all references to the existing swap chain are released so that a new one can be created. Notify the renderers that device resources need to be released. The HandleDeviceLost method releases the swap chain and notifies app components to release device resources: m_swapChain = nullptr Release any references to graphics device resources created with the previous Direct3D device those resources are now invalid, and all references to the swap chain must be released before a new one can be created.

HandleDeviceLost will reenter this methodĪny time your app receives the DXGI_ERROR_DEVICE_REMOVED error, it must reinitialize the Direct3D device and recreate any device-dependent resources. Do not continue execution of this method. If the device was removed for any reason, a new device and swap chain will need to be created. Static_cast(m_d3dRenderTargetSize.Height), Static_cast(m_d3dRenderTargetSize.Width), The template checks the HRESULT returned by ResizeBuffers: // If the swap chain already exists, resize it. When a graphics device is removed or reset, the desktop resolution often changes, resulting in a window size change.The app might have moved to a monitor that's attached to a different graphics device.Resizing the swap chain requires a call to the underlying DXGI adapter, which can return the device removed error.This is a good place to check for DXGI_ERROR_DEVICE_REMOVED or DXGI_ERROR_DEVICE_RESET for several reasons: If (hr = DXGI_ERROR_DEVICE_REMOVED || hr = DXGI_ERROR_DEVICE_RESET)Īlso, include a check for the device removed error when responding to window size changes. If necessary, it calls a method to handle the device removed condition: // If the device was removed either by a disconnection or a driver upgrade, we Then, check whether it returned DXGI_ERROR_DEVICE_REMOVED or DXGI_ERROR_DEVICE_RESET.įirst, the template stores the HRESULT returned by the DXGI swap chain: HRESULT hr = m_swapChain->Present(1, 0) Īfter taking care of all other work for presenting the frame, the template checks for the device removed error.

Present the frame by calling IDXGISwapChain::Present (or Present1, and so on). Include a check for the device removed error in the rendering loop. Code examples are provided from the DirectX 11 App (Universal Windows) template provided with Microsoft Visual Studio 2015. This walkthrough explains how Direct3D 11 apps and games can detect and respond to any circumstance where the graphics adapter is reset, removed, or changed. When such circumstances arise, DXGI returns an error code indicating that the Direct3D device must be reinitialized and device resources must be recreated.

A graphics adapter is physically attached or removed.

The graphics device stops responding and is reset.

The system changes from a power-saving graphics adapter to a performance graphics adapter.

However, it is still possible for graphics adapter availability to change. Direct3D 11 uses virtual graphics device interfaces, enabling multiple programs to share the same physical graphics device and eliminating conditions where apps lose control of the Direct3D device. For example, when a full-screen Direct3D 9 application loses focus, the Direct3D device becomes "lost " any attempts to draw with a lost device will silently fail. In DirectX 9, applications could encounter a " device lost" condition where the D3D device enters a non-operational state.

This topic explains how to recreate the Direct3D and DXGI device interface chain when the graphics adapter is removed or reinitialized.
