--- Comment #5 from Matt Turner <mattst88 at gmail.com> ---
There are a number of performance improving features missing on Ironlake, like
HiZ, instruction compaction, or fast color clears. We're lacking some features,
but there's not really a bug here.

Kristian is generalizing the fast color clear implementation, so we might be
able to add Ironlake support. I've got some work in progress code for Ironlake
instruction compaction. And in general, we're always making compiler
improvements to speed up shader code.

Hopefully it'll get some speed ups, but Ironlake isn't a high priority to tell
the truth.
