Yes, I am sure he reports regressions. Chasing it down must have been a time consuming task, and he is arguably the most contributing journalist for GNU/Linux on earth. I have no idea how he found time to chase it down while still churning out continuous updates on what is now the established goto place for anybody who cares about graphics on linux, and the goto place for anybody who knows shit about benchmarking. You should learn to show appreciation when people work 24/7 for years to improve your life, and does it more effectively than most.
I am sick and tired of this type of bashing against the few that really contribute big-time.
