创建 DirectX 12 命令队列时出现一个奇怪的错误。其他 DX12 应用程序能够在同一台机器上成功启动。

我的电脑使用该D3D_FEATURE_LEVEL_11_0 if块。测试用的显卡是NVIDIA GT 740，驱动361.75

这是正在使用的代码（最小化）：

#include <Windows.h>
#include <d3d12.h>
#include <dxgi1_4.h>
#include <comdef.h>
#include <D3d12sdklayers.h>
#include <string>

#pragma comment(lib,"d3d12.lib")

#pragma comment(lib,"d3dcompiler.lib")
using namespace std;

LRESULT WINAPI WndProc(HWND hwnd, UINT msg, WPARAM wParam, LPARAM lParam) {
    switch (msg)
    {
    case WM_DESTROY:
        PostQuitMessage(0);
        return 0;
    default:
        return DefWindowProc(hwnd, msg, wParam, lParam);
    }
}
int WINAPI wWinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance,
    LPTSTR lpCmdLine, int nCmdShow) {
    UNREFERENCED_PARAMETER(hPrevInstance);
    UNREFERENCED_PARAMETER(nCmdShow);
    UNREFERENCED_PARAMETER(lpCmdLine);

    wchar_t* WindowClass = L"Papergate";
    WNDCLASSEX wc;
    ZeroMemory(&wc, sizeof(WNDCLASSEX));

    wc.cbSize = sizeof(WNDCLASSEX);
    wc.style = CS_HREDRAW | CS_VREDRAW;
    wc.lpfnWndProc = WndProc;
    wc.hInstance = hInstance;
    wc.hbrBackground = (HBRUSH)(COLOR_WINDOW + 2);
    wc.lpszClassName = WindowClass;

    if (!RegisterClassEx(&wc))
    {
        return 1;
    }

    HWND hwnd = CreateWindowEx(NULL, wc.lpszClassName, WindowClass,
        WS_OVERLAPPEDWINDOW,
        CW_USEDEFAULT, CW_USEDEFAULT,
        CW_USEDEFAULT, CW_USEDEFAULT,
        NULL, NULL, hInstance, NULL);

    if (!hwnd)
    {
        UnregisterClass(WindowClass, hInstance);
        return 1;
    }
    ShowWindow(hwnd, SW_SHOWDEFAULT);
    UpdateWindow(hwnd);

    ID3D12Device* device;
    HRESULT result = D3D12CreateDevice(NULL, D3D_FEATURE_LEVEL_12_1,
        __uuidof(ID3D12Device), (void**)&device);
    if (FAILED(result))
    {
        result = D3D12CreateDevice(NULL, D3D_FEATURE_LEVEL_12_0,
            __uuidof(ID3D12Device), (void**)&device);
        if (FAILED(result))
        {
            result = D3D12CreateDevice(NULL, D3D_FEATURE_LEVEL_11_0,
                __uuidof(ID3D12Device), (void**)&device);
            if (FAILED(result)) {
                _com_error error(result);
                MessageBox(hwnd, error.ErrorMessage(),
                    (wstring(L"Error: ") + to_wstring(__LINE__)).c_str(),
                    MB_OK);
                return 2;
            }
        }
    }

    ID3D12Debug* debugInterface;
    if (SUCCEEDED(D3D12GetDebugInterface(IID_PPV_ARGS(&debugInterface))))
    {
        debugInterface->EnableDebugLayer();
    }

    D3D12_COMMAND_QUEUE_DESC commandQueueDesc;
    commandQueueDesc.Flags = D3D12_COMMAND_QUEUE_FLAG_NONE;
    commandQueueDesc.NodeMask = 0;
    commandQueueDesc.Priority = D3D12_COMMAND_QUEUE_PRIORITY_NORMAL;
    commandQueueDesc.Type = D3D12_COMMAND_LIST_TYPE_DIRECT;
    ID3D12CommandQueue* commandQueue;
    result = device->CreateCommandQueue(&commandQueueDesc, __uuidof(ID3D12CommandQueue), (void**)&commandQueue);
    if (FAILED(result)) {
        _com_error error(result);
        MessageBox(hwnd, error.ErrorMessage(),
            (wstring(L"Error: ") + to_wstring(__LINE__)).c_str(), MB_OK);
        result = device->GetDeviceRemovedReason();
        error = _com_error(result);
        MessageBox(hwnd, error.ErrorMessage(),
            (wstring(L"Error: ") + to_wstring(__LINE__)).c_str(), MB_OK);
        debugInterface->Release(); device->Release(); return 2;
    }

    MSG msg;
    ZeroMemory(&msg, sizeof(MSG));
    while (GetMessage(&msg, NULL, 0, 0) && msg.message != WM_QUIT)
    {
        TranslateMessage(&msg);
        DispatchMessage(&msg);
    }

    commandQueue->Release();
    device->Release();
    UnregisterClass(WindowClass, hInstance);
    return 0;
}

我分别在第 97 行和第 102 行收到以下错误：

The GPU device instance has been suspended. Use GetDeviceRemovedReason to determine the appropriate action.

第二个错误：

The GPU will not respond to more commands, most likely because some other application submitted invalid commands.
The calling application should re-create the device and continue.

这似乎很可能是某种驱动程序错误。检查您的硬件是否有更新的驱动程序。您应该尝试在此VSIX中使用 Direct3D12 游戏模板，看看它们是否遇到相同类型的问题（有关模板的更多详细信息，请参阅此博客文章）。

您调用各种功能级别的级联模式D3D12CreateDevice是不寻常的，并且没有必要。如果您的应用程序可以在 Direct3D Feature Level 11.0 或更高版本上运行，则只需使用D3D_FEATURE_LEVEL_11_0一次。您应该将支持的最低功能级别传递给此函数。

如果 Direct3D 12 设备确实支持更高的功能级别，您可以通过检查单个功能或使用CheckFeatureSupportD3D12_FEATURE_FEATURE_LEVELS来发现：

// Create the DX12 API device object.
DX::ThrowIfFailed(D3D12CreateDevice(
    adapter.Get(),
    m_d3dMinFeatureLevel,
    IID_PPV_ARGS(&m_d3dDevice)
    ));

// Determine maximum supported feature level for this device
static const D3D_FEATURE_LEVEL s_featureLevels[] =
{
    D3D_FEATURE_LEVEL_12_1,
    D3D_FEATURE_LEVEL_12_0,
    D3D_FEATURE_LEVEL_11_1,
    D3D_FEATURE_LEVEL_11_0,
};

D3D12_FEATURE_DATA_FEATURE_LEVELS featLevels =
{
    _countof(s_featureLevels), s_featureLevels, D3D_FEATURE_LEVEL_11_0
};

HRESULT hr = m_d3dDevice->CheckFeatureSupport(D3D12_FEATURE_FEATURE_LEVELS,
    &featLevels, sizeof(featLevels));
if (SUCCEEDED(hr))
{
    m_d3dFeatureLevel = featLevels.MaxSupportedFeatureLevel;
}
else
{
    m_d3dFeatureLevel = m_d3dMinFeatureLevel;
}

请记住，D3D_FEATURE_LEVEL_12_0本质D3D_FEATURE_LEVEL_12_1上只是D3D_FEATURE_LEVEL_11_1一些强制性的可选功能。如果您的应用程序已经在 11.x 中检查它们，那么没有理由“要求”12.0 或 12.1。请参阅MSDN。

对于绝大多数 Direct3D 12 游戏和应用程序来说，D3D_FEATURE_LEVEL_11_0还是D3D_FEATURE_LEVEL_11_1不错的选择。请记住，虽然 AMD/ATI 很早就支持 Feature Level 11.1，但 NVIDIA DirectX 11 部件在一段时间内仅支持 11.0 和一些可选功能。
