rts/Rendering/GL/FBO.cpp:445 is glRenderbufferStorageMultisampleEXT(GL_RENDERBUFFER_EXT, samples, format, width, height); I did a bit of search and i wonder if GLEW_ARB_framebuffer_object is enough to try a multisampled render buffer, perhaps GLEW_EXT_framebuffer_multisample is needed. |

Forget my comment above, GLEW_ARB_framebuffer_object includes GLEW_EXT_framebuffer_multisample. Btw, we use a hardcoded samples of 16, i think we should check GL_MAX_SAMPLES. |

Here is an interesting thread about multisampling on intel: http://www.opengl.org/discussion_boards/showthread.php/181269-Yet-another-Intel-multisample-thread Last post seem like a possible solution: FWIW, I check (GL_ARB_multisample &&GL_EXT_framebuffer_multisample) for whether MSAA is supported and then cache the GL_MAX_SAMPLES value as the indicator of whether to use MSAA. ie if it returns 0, its going down the non-MSAA code path. |

I now see that we check GL_MAX_SAMPLES_EXT but i suspect its a bit too late, we already gone down the multisample branch. |

msafwan, please test this on your intel machine. jk, this is probably something you want to cleanup if it solves the problem. If it dont solve the problem we revert it. |
