The challenge enabling things like tiling isn't "not knowing how to enable", it's that enabling tiling requires changes in a lot of different places and since the driver architectures are different you can't just look at the proprietary driver and find the corresponding areas in the open driver.

Well, thanks for the answer.
Michael, could you test this with the 2D tiling patch? I wonder how much these two combined would increase the performance.
It appears though, that they understood recently that the good quality on the software side is essantial. What they still lack is the realisation that:
"If we pay 5 more guys we could conquer the _whole_ linux world."
This would mean roughly 2.5% increase in sales for them. I guess that means a higher revenue than the salary of those guys, i.e. profit.
Just my 2 cents though...
Now hold on, making a great mesa driver might make a difference for the technical users and those that care about their freedom, but there are hordes of Ubuntu users out there that just use Linux because it's free as in beer and couldn't care less what driver they use.
And don't get me wrong, I appreciate AMD's effort for making a free as in speech driver, and I'm using the radeon driver on my HD3650 from the days there was no 3D acceleration, not even the classical r600 driver. I just don't live the illusion that the majority of Linux users share my view regarding freedom.
