--- Comment #110 from Henri Verbeet hverbeet@gmail.com 2011-04-26 07:03:42 CDT --- Well, the way to fix this is to implement support for software shaders. That shouldn't be terribly hard, but still at least a couple of months of work for vertex shaders, and probably more than that for fragment shaders. You'd probably want to use LLVM.
