--- Comment #3 from Kenneth Graunke <kenneth at whitecape.org> ---
The benchmark should do the same thing, but adding additional tracked state
atoms increased the draw call overhead.  And these are CPU overhead benchmarks.

I don't think it's worth tracking as a regression.  We can't exactly retract
core features.  We just need to optimize away draw call CPU overhead.
