C++ DirectX11 与多视频适配器 (GPU) PC

通常，DirectX11初始化从创建DirectX11设备开始:

D3D_DRIVER_TYPE driverTypes[] =
{
    D3D_DRIVER_TYPE_HARDWARE,
    D3D_DRIVER_TYPE_WARP,
    D3D_DRIVER_TYPE_REFERENCE,
};

UINT nNumDriverTypes = ARRAYSIZE(driverTypes);

// Feature levels supported
D3D_FEATURE_LEVEL featureLevels[] =
{
    D3D_FEATURE_LEVEL_11_0,
    D3D_FEATURE_LEVEL_10_1,
    D3D_FEATURE_LEVEL_10_0,
    D3D_FEATURE_LEVEL_9_1
};

UINT nNumFeatureLevels = ARRAYSIZE(featureLevels);
D3D_FEATURE_LEVEL featureLevel;

// Create device
for (UINT n = 0; n < nNumDriverTypes; ++n)
{
    hr = D3D11CreateDevice(nullptr,driverTypes[n],nullptr, D3D11_CREATE_DEVICE_BGRA_SUPPORT,featureLevels,nNumFeatureLevels,
        D3D11_SDK_VERSION,&m_pDevice,&featureLevel,&m_pDeviceContext);

然后为窗口创建交换链:

IDXGIDevice* pDXGIDevice = nullptr;
HRESULT hr = m_pDevice->QueryInterface(__uuidof(IDXGIDevice),
    reinterpret_cast<void**>(&pDXGIDevice));
if (SUCCEEDED(hr))
{
    IDXGIAdapter* pDXGIAdapter = nullptr;
    hr = pDXGIDevice->GetParent(__uuidof(IDXGIAdapter),
        reinterpret_cast<void**>(&pDXGIAdapter));   
    if (SUCCEEDED(hr))
    {
        IDXGIFactory2* pDXGIFactory = nullptr;
        hr = pDXGIAdapter->GetParent(__uuidof(IDXGIFactory2),
            reinterpret_cast<void**>(&pDXGIFactory));
        if (SUCCEEDED(hr))
        {
            DXGI_SWAP_CHAIN_DESC1 desc = {};
            desc.SwapEffect = DXGI_SWAP_EFFECT_FLIP_SEQUENTIAL;
            desc.BufferCount = 2;
            desc.Width = nWindowWidth;
            desc.Height = nWindowHeight;
            desc.Format = DXGI_FORMAT_B8G8R8A8_UNORM;
            desc.BufferUsage = DXGI_USAGE_RENDER_TARGET_OUTPUT;
            desc.SampleDesc.Count = 1;
            desc.SampleDesc.Quality = 0;        

            hr = pDXGIFactory->CreateSwapChainForHwnd(m_pDevice,hWnd,
                &desc,nullptr,nullptr,&m_pSwapChain);

我的电脑有两个连接到两个显示器的视频适配器.Adapter1与Monitor1相连.Adapter2连接到Monitor2.我知道我可以枚举DXGI适配器，并使用特定的适配器for D3D11CreateDevice来创建DirectX11设备，但这对我没有帮助，因为我不知道哪个监视器显示我的窗口.

• 如何找到显示窗口的显示器？我必须使用那个监视器视频适配器吗，还是可以使用任何适配器？
• 如果用户将窗口从Monitor1移动到Monitor2，会发生什么？另一个适配器开始显示窗口了吗？
• 总的来说，DirectX11如何处理这样的问题？
