我尝试从互联网上找到的tuturial获得高质量的抗锯齿效果（http://www.rkoenig.eu/index.php?option=com_content&view=article&id=21:chapter-3- DAS-一个吧-echte-3D-OBJEKT＆安培; CATID = 6：DirectX10的-基础＆安培; ITEMID = 3）。但没有达到很好的解决方案。
我已经将多重采样设置为最大值：
m_swapChainDesc.SampleDescription = new DXGI.SampleDescription(8,0);
对我看来，渲染图像的像素大小大于我屏幕的实际像素大小。
非常感谢您提供的宝贵意见

这是一个古老的问题，但遗憾的是它从未得到回答;我在Google上偶然发现了它，所以我想回答它可能会帮助其他人......
首先，Pascal，你没有将MSAA设置为最大值......你使用的是8：0，这意味着质量为0（零）的8个样本......绝对不是最大值。 “max”取决于本地计算机上安装的GPU。所以它因PC而异。这就是为什么DirectX应用程序需要使用DXGI来正确枚举硬件设备并确定哪些设置有效。这不是一个微不足道的话题，需要你做一些自己的研究和实践。 DirectX SDK文档和示例/教程是一个很好的起点，并且还有很多其他材料可以在网上找到。但是在我的机器上，例如，我的GTX-580 GPU可以支持8:16 MSAA（可能更高，但尚未检查）。
因此，您需要学习使用DXGI来枚举您的图形卡和显示器，并找出它可以支持的MSAA级别（以及其他图形功能/设置）。例如，这是您能够找出“最大”MSAA设置或显示器正确刷新率的唯一方法。如果你很聪明，你会自己为你的游戏引擎编写一个小型库或组件，它将为你枚举硬件设备并找出最佳的图形设置，这样你就不必为将来的项目重复这样做。
