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

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

    There's been a number of recent open-source driver improvements that have come about for modern ATI/AMD Radeon graphics cards under Linux, but not all of these features have yet to be merged or enabled by default (e.g. 2D color tiling, PCI Express 2.0, and HyperZ). With some basic tweaks, can the open-source Radeon Gallium3D driver now compete with AMD's proprietary Catalyst Linux driver when it comes to OpenGL performance? Let's see.

    Nexuiz/Xonotic and OpenArena are looking great > 50%.

    Too bad the mesa driver can't keep this performance with Doom3, Warsow and co.

    Btw what is going on with Reaction Quake? Must be hitting some slow path with mesa.

    It's interesting to note that the r300g hardware is significantly outperforming the r600g hardware in that test. It seemed to be about the only case where that happened, which is a lot better than things used to look.

    Default Hmm

    That kind of benchmarks start to become boring...

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

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

    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..

    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.

    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?

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

    It's not the drivers but the hardware.
    Intel has the best video acceleration around in their open source driver.
    I'm sure Bridgman could better explain (and for that matter, I'm sure this has already been answered many times), but I think there is better decoupling of the decode/encode and DRM in Intel than AMD.
