> ## Name

> cg_2_2_0010 - Cg Toolkit 2.2 October 2009

> ## Summary

> - Allow compiler options in effect compile statements. e.g. VertexProgram = compile vp40 "-po PosInv=1" shader();
> - Better performance when running on multicore CPUs
> - Choosing the "latest" profile is now deferred until effect validation
> - Improved the inverse matrix computation in cgGLSetStateMatrixParameter
> - Better memory behavior when a program is repeatedly recompiled
> - Fixed an issue when using PSIZE semantic with ps_3_0 and ps_4_0 profiles
> - cgCombinePrograms now works with CG_OBJECT programs
> - cgGetNextProgram was always returning 0
> - Fixed a problem with effect parameters and cgGLGetTextureEnum
> - Allow comments prior to the shader version in D3D asm blocks of an effect
> - HLSL10: Mark globally scoped temporaries 'static' to keep them out of constant buffers
> - HLSL10: Allow any semantic for varyings provided the semantics match between stages
> - HLSL10: Fix handling of TEXUNITn semantic
> - HLSL10: Added support for arrays of samplers
> - HLSL10: Empty structs for uniform parameters crashed the D3D compiler
> - Fixed a problem when connecting parameters of type string
> - Corrected issues in the fp20 profile on Solaris
> - Now using MesaGLUT-7.5 for GLUT on Windows
