------- Additional Comments From hverbeet@gmail.com 2007-24-01 02:42 ------- GLSL is the GL Shading Language. There is a registry key, "//HKCU/Software/Wine/Direct3D/UseGLSL" which you can set to "enabled". This enables (for now experimental) support for using GLSL for the shader implementation, and should support vs_2_0. See also http://wiki.winehq.org/UsefulRegistryKeys
