Not sure probably what happens in some other games like in bug 86038 , major blackiness which came from lighting seems to gone using llvm-3.6 there too, but still not completely even if you use llvm-3.6, most likely this comment goes to the right track: https://bugs.freedesktop.org/show_bug.cgi?id=83510#c8 It is discussed on mesa ml, so hopefully it will get fixed soon :) http://lists.freedesktop.org/archives/mesa-dev/2014-December/071973.html
