In 2002, Microsoft released DirectX 9 with support for the use of much longer shader programs than before with pixel and vertex shader version 2.0. Microsoft has continued to update the DirectX suite since then, introducing Shader Model 3.0 in DirectX 9.0c, released in August 2004.
Direct3D 10.1 is an incremental update of Direct3D 10.0 which shipped with, and required, Windows Vista Service Pack 1, which was released in February 2008.[39] This release mainly sets a few more image quality standards for graphics vendors, while giving developers more control over image quality.[40] It also adds support for cube map arrays, separate blend modes per-MRT, coverage mask export from a pixel shader, ability to run pixel shader per sample, access to multi-sampled depth buffers[41] and requires that the video card supports Shader Model 4.1 or higher and 32-bit floating-point operations. Direct3D 10.1 still fully supports Direct3D 10 hardware, but in order to utilize all of the new features, updated hardware is required.[42]

This is exactly what happened at the triangle. We have 3 vertices and thus 3 colors, and judging from the triangle's pixels it probably contains around 50000 fragments, where the fragment shader interpolated the colors among those pixels. If you take a good look at the colors you'll see it all makes sense: red to blue first gets to purple and then to blue. Fragment interpolation is applied to all the fragment shader's input attributes.

Consider a Pixel Shader that operates only on pixel-frequency inputs (e.g. all attributes have one of the following interpolationmodes(16.4): constant, linear, linear_centroid, linear_noperspective or linear_noperspective_centroid).Implementations need only execute the shader once per pixel and replicate the results to all samples in the pixel.Now suppose code is added to the shader that generates new outputs based on reading sample-frequency inputs. The existingpixel-frequency part of the shader behaves identically to before. Even though the shader will now execute at sample-frequency(so the new outputs can vary per-sample), each invocation produces the same result for the original outputs.
With a forced sample count/pattern selected at the rasterizer (ForcedSampleCount > 0), pixels are candidates for shader invocation based on the selected sample pattern,independent of the RTV ("output") sample count. The burden is then on shader code to make sense of the possible mismatch between rasterizer and output storage sample count,given the defined semantics.
Pixel Shaders always run in minimum 2x2 quanta to be able to support derivative calculations,regardless of the RenderTarget sample count. These Pixel Shader derivative calculations, used in texture filtering operations,but also available directly in shaders, are calculated by taking deltas of data in adjacent pixels. This requiresdata in each pixel has been sampled with unit spacing horizontally or vertically.
If an application violates the 1:1 property when using the TILEABLE flag on CopySubresourceRegion, such as reading into a different pixel, or into a shader stage other than the Pixel Shaderin the second pass, the the data being read is undefined (it will have been generated by an unknown rendering pass by the application or uninitilized).
Shader Complexity Mode is used to visualize the number of shader instructions being used to calculate each pixel of your scene. It is generally a good indication of how performance-friendly your scene will be. In general, it is used to test overall performance for your base scene, as well as to optimize particle effects, which tend to cause performance spikes with a large amount of overdraw for a short period of time.
