Which OpenGL extensions does dolphin use? - ulikmadik - 11-24-2015
I'm on linux using recent opensource radeon drivers, which only support up to OpenGL 4.1 proper, however, there are many extensions already implemented for 4.2 and upwards. Normally I could override the GL version with an env. variable and blacklist the unavailable extensions with another, for example :
MESA_GL_VERSION_OVERRIDE=4.2 MESA_GLSL_VERSION_OVERRIDE=420 MESA_EXTENSION_OVERRIDE=-GL_ARB_shader_image_load_store dolphin-emu
But dolphin still spits a shader compilation error at me complaining about GL_ARB_shader_image_load_store, so before I go overriding all available extension one by one, without overriding the GL version, I'd like to know which extensions exactly dolphin requests to avoid unnecessary time spending..

Thank you. Turns out the GL_ARB_shader_image_load_store wasn't being disabled due to a bug in MESA, nothing to do with the emulator. Adding specific extensions to a GL 4.1 context worked as it should. This one is solved.
