DirectX 11获取图形卡的说明

Question

我正在尝试遍历系统上的可用GPU，并将每个GPU的描述打印到控制台上。我有用于检索它们的代码，但我无法弄清楚如何获取描述。

std::vector <IDXGIAdapter1*> availableAdapters = EnumerateAdapters();

for_each(availableAdapters.begin(), availableAdapters.end(), [](IDXGIAdapter1* adapter) {
    auto myAdapter = *adapter;
    auto adapterDescription = new DXGI_ADAPTER_DESC1();
    myAdapter.GetDesc1(adapterDescription);
    // Print description to console here
});

我收到指向auto myAdapter = *adapter;行的编译时错误，但是error C2259: 'IDXGIAdapter1' : cannot instantiate abstract class

我正在使用DirectX 11，Windows 64位和Visual Studio 2012.感谢您的帮助！

试

auto& myAdapter = *adapter;
auto adapterDescription = DXGI_ADAPTER_DESC1();
myAdapter.GetDesc1(&adapterDescription);
