An Optimized Open-Source Driver Tries To Compete With AMD Catalyst

[Pontostroy]

Nice, results are very close to my.

I can't see where the optimized open source driver is trying to compete with the catalyst. The binary blob is still miles ahead.

Yes, but if it has 60+ FPS for the applications you need competing (optimizing remaining "bottlenecks") is kind of pointless. That's competing enaugh for me.

Video acceleration is also still a problem with the open source drivers. If at least that would work, the open source driver would be suitable for HTPCs.

It would be definitely very good if it was supported for more video codecs, but what CPU does your HTPC have and what quality of videos do you want to play?

In the current state however it is pretty much useless, except for desktop effects.

Except for Playing Portal 2 in wine or all of the games in the humble bundles.

Wow... that white text on cyan background is an all-time low readability record for Phoronix... what's up with the CGA colors?

BTW, was the power profile default or high?

The low-end results (6450, 4550) are really sad. Not only is catalyst 4-6x the speed, the tweaks also have little to no effect.

What was the problem with 3650? I own one of those and it works fine for me with both mesa-8.0 and latest git. And you can imagine I was most interested in the results for that card, as I can compare them with my own system.

I wonder if enabling S3TC might improve the performance of the radeon driver. Well this can be an idea for the next article

Yeah, I really don't need more 3D performance and I'm so tired of waiting for Gallium3D VDPAU, especially when it's being held up for legal reasons and may never be released. I think I'm just going to swap my RadeonHD 4550 with a GeForce 8400GS from another computer. Problem solved..

I think you mean UVD (and proper PM) is held back due to legal reasons. The state tracker is not ready yet because there are not many people working on it AFAIK.
