I'm looking forward to it. Sea Islands used in Kabini still has some occasional rendering artifacts in KDE. Also gaming performance is horrible, but then, it might be that these very games are using emul-linux-x86-opengl (32 bit libs on 64 Gentoo), which contains an older mesa which is not suitable for Kabini chips.

why don't you switch to no-emul profile. It works nicely and I had to add just a few packages to /etc/portage/package.accept_keywords

the thirteen patches don't deliver any breakthrough features or big performance gains, but mostly comes down to maintenance work and various fixes.

Actually there are 4 dependant patches before that:

And when someone touch VBOs in some way, there should be some performance difference Perf can go low or up, didn't tried yet.

@Adarion

My Kabini works fine, but yeah 32bit games are always little slower with fglrx too.

Yup , quick tried and not good - perf goes down this time, -3% mostly but sometimes even -15%

Then try find which one in particular drops the performance and reports it ?

Yeah, i will see those vbos seems isn't checking uses_centroid now...

[dungeon]

Only it is not just a single one, but last two 12 and 13 - that is it

But yeah 12 is where main slowness begin:

This sounds like Gentoo. I've seen a few things about going full-multilib instead of using the emul-libs, but don't know how ready it really is for prime-time. I have one game in particular that won't run with the emul-libs on my Kaveri for this same reason, so I only play it on a different (and slower) computer. Going full multilib might fix that.

Can you give some pointers, and more important - experience?
