[Mesa-dev] [Bug 89018] Civilization: Beyond Earth terrain section not rendered

--- Comment #16 from Sami Liedes <sami.liedes at iki.fi> ---
I think this might be related to the color rendering weirdness: On fglrx, CivBE
uses the GL_NV_half_float extension, which is not available on Mesa. Looking at
interesting words or enums that are present in one of the traces but not the
other (after apitrace dump):

* The fglrx dump mentions GL_DEPTH, GL_DEPTH_COMPONENT, GL_DEPTH_COMPONENT16,
GL_R16F, GL_RG, GL_RG16F, glColorMaski, while running under mesa does not.

  * I believe the pixel formats here are probably those half floats, and if
that's unsupported by mesa, then it's no big wonder the color channels are off?

* The mesa dump mentions nan in glUniform4fv calls. That cannot be good? :P
