Latest kernel improves Radeon performance up to 90%
A friend linked me to this article.[www.phoronix.com] They discovered that the 3.12 kernel improved performance of Radeon HD cards up to 90%... and the crazy thing is, no one knows why. Seriously, AMD themselves and even the people who coded the new kernel have no idea what's going on.

This even applies to some of the so-called legacy cards, which I found especially odd since I though the 13.1 driver those cards are required to use doesn't actually work with the current kernel, let alone upcoming ones. That's why I haven't been able to upgrade from Kubuntu 12.04. Can anyone confirm a way to make it work? I kind of really really want to upgrade next year now if 14.04 has the new kernel in it.

I think Croteam will be happy, they've been fighting with the stupid CPU governor for ages.

The sucky thing about having two different drivers, one gets the breaks while the other doesn't, and you end up screwed.

With all the work thats been going into the open source driver recently, it's pretty clear that AMD plans to default to this in the future. They hired a ton of people in the last year alone to work on it, and it has been improving in leaps and bounds recently. Support for newer cards is catching up.

The performance and features we're now seeing for the open source drivers is the culmination of many years of groundwork. Lots of architectural changes had to happen across the entire graphics stack leading up to this, so it was a bit difficult to see the results untill recently. Of course, not quite yet for brand new cards.

This does suck for people who do have an SI card and are forced to use fglrx. I wouldn't touch fglrx with a flaming pole, but it's the only option for now.

Tell me about it... However while 2D experiene with fglrx is better than Nvidia, 3D apps run like crap :/ Hopefully it will get fixed soon.
