I need help exposing a different version of "Max GLES1 profile version: 1.1" (glxinfo). I need this in order to launch X-Plane 11 and to enable PBR shading on X-Plane 10. I cannot for the life of me make it happen. Here's what I've tried so far: /X-Plane-x86_64 --force_run MESA_EXTENSION_OVERRIDE=-GL_EXT_texture_array MESA_GLES_VERSION_OVERRIDE=4.5 MESA_GL_VERSION_OVERRIDE=4.5 MESA_GL_VERSION_OVERRIDE=4.1 MESA_GL_VERSION_OVERRIDE=4.3 MESA_GLES1_VERSION_OVERRIDE MESA_GLES1_VERSION --no_ubos --no_array_tex --force_run --unlimited_glsl I can override GLES version, but there's no documentation on how to override the GLES1 version, anywhere. I found this patch, but I need mesa-git in order to use the amdgpu Kernel driver with my GCN 1.0 card, so it's not doable to me (I can't compile it that often, or at all for that matter, since my processor is reaching it's TCTL and I need an aftermarket cooler). Any ideas?
