From 31500f252212a5aa3ffb779b7bac52a14f25908c Mon Sep 17 00:00:00 2001 From: Ryan Houdek Date: Sat, 30 Mar 2013 23:27:24 -0500 Subject: [PATCH] Fix Intel Ironlake since it doesn't support version 120 of GLSL. I don't have Ironlake so it is hard to test. Dropping the shaders to version 120 worked here for me, ATI may be giving me some slack though. --- Source/Plugins/Plugin_VideoOGL/Src/ProgramShaderCache.cpp | 6 +++++- 1 file changed, 5 insertions(+), 1 deletion(-) diff --git a/Source/Plugins/Plugin_VideoOGL/Src/ProgramShaderCache.cpp b/Source/Plugins/Plugin_VideoOGL/Src/ProgramShaderCache.cpp index 4c516853d7..5f4df23eca 100644 --- a/Source/Plugins/Plugin_VideoOGL/Src/ProgramShaderCache.cpp +++ b/Source/Plugins/Plugin_VideoOGL/Src/ProgramShaderCache.cpp @@ -496,6 +496,10 @@ void ProgramShaderCache::CreateHeader ( void ) #else bool glsl140_hack = false; #endif + // Intel HD Graphics on the Ironlake chipset has been abandoned by Intel + // It supports every feature we need but not GLSL 1.3 + // This is to check if it is Ironlake then drop to GLSL 1.2 + bool glsl120_hack = strstr(g_ogl_config.gl_renderer, "Ironlake") != 0; snprintf(s_glsl_header, sizeof(s_glsl_header), "#version %s\n" @@ -519,7 +523,7 @@ void ProgramShaderCache::CreateHeader ( void ) "#define lerp(x, y, z) mix(x, y, z)\n" - , glsl140_hack ?
