我正在设计一个使用 DirectX 11 API 的游戏引擎，特别是延迟上下文的使用。基本思想是让每个设备状态都给定其自己的延迟上下文，然后在渲染所有几何图形后，通过迭代每个延迟上下文并在直接上下文上执行其命令列表来显示它。我通过使用线框着色器在屏幕上简单地绘制两个三角形来测试这一点，仅此而已。所有 DirectX 调用都不会返回错误，即使在 PIX 调试报告中查看时也是如此，但是一旦IDXGISwapChain::Present(0,0调用 )，整个屏幕就会变黑然后返回。然后屏幕右下角会弹出一个错误框，说明显示驱动程序“已停止响应并成功恢复”。查看 PIX 日志，我发现有一行说明“D3D11: Removing Device" 在 PIX 日志中调用的 pre 和 post 块之间。post 块中显示的返回值是DXGI_ERROR_DEVICE_REMOVED。我不太确定该怎么做。PIX 日志如下：

如果还需要什么，请告诉我。我没有发布代码主要是因为它扩展了近 20 个单独的类，但我可以发布缓冲区内容、HLSL 和逻辑背后的解释。

更新：

我已经在一定程度上解决了上面的问题，部分原因很可能是由于没有设置任何着色器、没有索引缓冲区、没有顶点缓冲区和没有常量缓冲区。原来的问题还没有解决，但是在处理这个问题的过程中，我有了一个新的想法。我从来没有打电话ID3D11DeviceContext::Begin(0)。但是，在从设备状态类获取设备上下文并在该上下文上调用 Begin 时，我最终会遇到访问冲突，并且指向ID3D11DeviceContext对象的指针被设置为零。这只发生在对 的调用上Begin，删除调用会导致行为停止。浏览 DirectX SDK 中的示例代码，我在任何时候都找不到要开始的显式调用。这个电话有必要吗？这似乎有点离题，但如果命令列表因此而被破坏，这可能是原因Present正在移除设备。

相关代码：

if(FAILED(devstate->BeginDraw(inlayout,&dc)))
{
    return ACERROR_ALREADYDRAWING; //error handling block.
}
//dc->Begin(0); //access violation: error accessing location 0x00000024
for(UINT i=Shader_Vertex;i<Shader_Count;i++)
{
    //set all relevant shaders to the device.
    (dc->*(vtbls[i].ShaderSet))(shaders[i],0,0);
}

在过去 6 天查看了代码后，我有了一个奇怪的发现：尽管我对 DirectX 9.0c 有很多了解，但在 DirectX 11 中进行编码是……不同的。在代码中发现了几个愚蠢的错误后，我设法在硬件设备上修复了错误，但奇怪的是，不是在 ref 设备上。我目前正在研究 DirectX 11 管道更改，然后试图弄清楚为什么我可以非常轻松地清除背景，但是尝试使用延迟上下文绘制三角形根本不起作用。

感谢所有试图提供帮助的人的建议。
