But that's still several months out, and you probably don't want to wait that long. In the meantime, you can do: export MESA_GL_VERSION_OVERRIDE=3.2 export MESA_GLSL_VERSION_OVERRIDE=150
before launching OilRush...and it should work. I haven't tested it specifically but that works for both Unigine Heaven and Unigine Valley.
It might be worth adding a driconf setting to overrides these in a 9.1.4 release...not sure what people think about that.
That screws up steam though, I get a whole bunch of these: /home/buildbot/buildslave_steam/steam_rel_client_ubuntu12_linux/build/src/vgui2/src/surface_opengl.cpp (569) : Assertion Failed: glIsTexture( id ) /home/buildbot/buildslave_steam/steam_rel_client_ubuntu12_linux/build/src/vgui2/src/surface_opengl.cpp (785) : Assertion Failed: glIsTexture( nTextureID ) == GL_TRUE
