Huge improvement coming to open source amd drivers
"For AMD Radeon customers using the open-source Linux graphics driver, the Linux 3.11 kernel is going to be mega exciting! Alex Deucher of AMD posted a set of 165 kernel patches today. Most notably, there's finally Dynamic Power Management (DPM) support for R600 GPUs up through Southern Islands hardware! Yes, there's finally dynamic power management in the open-source driver. Additionally, there's initial support for AMD "Sea Islands" hardware and there's also ASPM (Active State Power Management) support."

Good to see improvements for AMD open source drivers. However they are still far behind in regards to opengl, opencl. Poor ♥♥♥♥♥♥♥s are still stuck with Catalyst.

Better performance would be more interesting than power management features.

Maybe there is... Who tested?

Over the last year or so I've definitely noticed a pretty large increase in the FOSS AMD drivers performance. I haven't done any specific proper testing, but on my laptop and netbook, both AMD powered, whereas once they could barely handle anything except desktop effects, now they can play HD video and surprisingly even modest gaming (mostly the laptop of course, for gaming, a few years old Sony Vaio with a 4xxx series mobility card).

I didn't expect my laptop to even run TF2 but it does, and it's playable.

Imo that depends on if you have a laptop or a desktop, but the performance is probably better anyway.

Actually, we are just waiting on the last bits of GLSL 1.50 for OGL 3.2 compatibility, http://cgit.freedesktop.org/mesa/mesa/tree/docs/GL3.txt , once it's there all the work has already been done for full OGL3.3, thus it's a direct upgrade to 3.3 and as such support for all current Linux games since none as of yet require OGL4 support. Even on Windows there aren't any games that require DX11/OGL4, some recent games still even support DX9.0c/OGL2.1.

OpenCL http://dri.freedesktop.org/wiki/GalliumCompute/ on the other hand while coming along seems to be only a one or 2 man effort right now since theres a chicken and egg problem, there no big push for it due to no software really there to make use of it and theres no software to make use of it since theres no good OSS GPU implementation for it.

What all these update mean though is that those with an AMD APU or an HD6000 series GPU are now able to more or less get near full closed source performance out of their hardware without mess around with secret sauce at the system level, where it just doesn't belong.

Power management is necessary before they can allow engine reclocking and voltage tweaking for more performance. Other performance gains will be had from making the drivers more feature complete, since they still lack geometry shaders, and stippled and smooth primitives http://wiki.x.org/wiki/RadeonFeature and more hacking away on Gallium3D.

Tried this on both my netbook and Sony Vaio. Cooling and noise is improved magnificently on both machines. The Sony has a weird screen flickering problem with it enabled, but the netbook runs perfectly. I'm so happy, cos my netbook now has Catalyst level power management (or near enough) without me having to mess around with fglrx.

The Sony flickering is annoying but as this is quite new and in testing, there will be little bugs like this to iron out.
