| Windows 7 includes Direct3D 11, which adds support for Shader Model 5. This brings with it the addition of GPU compute shader capabilities, the ability to run multiple shader routines at once (subroutines), dynamic shader linking (optimizing shaders during runtime) and improved performance with added multithreading support. Textures of up to 16,384 × 16,384 pixels are now supported by Direct3D 11, and meshes can now dynamically increase their level of detail through the use of tessellation, offering smoother surfaces on models with lower polygon counts. Feature levels are now supported by Direct3D 11, allowing the use of older API versions (such as Direct3D 9) while creating a D3D11 device through the WARP API. Graphics resources can now allocate more than 4 GB of video memory, eliminating the 32-bit memory limit present in older Direct3D versions. | | Windows 7 包括 Direct3D 11，它增加了对 Shader Model（着色器模型）5 的支持。这带来了 GPU 计算着色器功能的增加，同时可以同时运行多个着色器例程（子例程）、动态着色器链接（在运行时优化着色器）以及通过增加多线程支持来提高性能。Direct3D 11 现在支持高达 16384×16384 像素的纹理，并且网格现在可以通过使用细分来动态增加它们的细节级别，从而在多边形数量较低的模型上提供更光滑的表面。Direct3D 11 现在支持功能级别，允许在通过 WARP API 创建 D3D11 设备时使用旧的 API 版本（例如 Direct3D 9）。图形资源现在可以分配超过 4 GB 的视频内存，消除了旧版 Direct3D 中存在的 32 位内存限制。 |
