Here is the good stuff, nothing else pertains to me.
Updated Shader Compiler
This release includes a new shader compiler that provides many optimizations and bug fixes for HLSL and Effect compilation. This updated version is available for shader models 2.x and 3.x using either FXC.exe or D3DX9_33.dll. For shader model 4.0, developers can use either FXC.exe or one of the new functions D3DX10CompileFromFile, D3DX10CompileFromResource, and D3DX10CompileFromMemory (contained in D3DX10_33.dll).
Effect Pools Sample
One of the downsides to using multiple effects in a single application is that many effect variables need to be set for each effect. Frequently, many of these variables are common between effects. Without a method for sharing variables or shaders between effects, many redundant state-setting calls will need to be made for each effect. Effect pools are meant to solve this problem. This sample demonstrates the use of effect pools on Direct3D 9 and Direct3D 10.
