    Default AMD Catalyst 9.8 Preview

    This month we are seeing a massive performance increase with a whole host of games as compared to the ATI Catalyst 9.7 driver. Detailed release notes are available for most of the game optimizations; here are the highlights:

    [...]
    UnigineTropics OpenGL performance improvements of up to 20%.
    [...]

    This release of the ATI Catalyst driver provides OpenGL 3.1 extension support. The following is a list of OpenGL 3.1 features and extensions added in ATI Catalyst 9.8:

    - Support for OpenGL Shading Language 1.30 and 1.40.
    - Instanced rendering with a per-instance counter accessible to vertex shaders (GL ARB draw instanced).
    - Data copying between buffer objects (GL EXT copy buffer).
    - Primitive restart (NV primitive restart). Because client enable/disable no longer exists in OpenGL 3.1, the PRIMITIVE RESTART state has become server state, unlike the Nvidia extension where it is client state. As a result, the numeric values assigned to PRIMITIVE RESTART and PRIMITIVE RESTART INDEX differ from the NV versions of those tokens. o At least 16 texture image units must be accessible to vertex shaders, in addition to the 16 already guaranteed to be accessible to fragment shaders.
    - Texture buffer objects (GL ARB texture buffer object).
    - Rectangular textures (GL ARB texture rectangle). o Uniform buffer objects (GL ARB uniform buffer object).
    - SNORM texture component formats.

    Support for new Linux operating systems
    This release of ATI Catalyst driver for Linux introduces support for the following new operating systems:

    - RHEL 4.8 production support
    - Ubuntu 9.04 production support

    ATI Catalyst™ Control Center - Linux Edition support for RandR 1.2 This release of the ATI Catalyst driver for Linux introduces ATI Catalyst Control Center - Linux Edition support for the RandR 1.2 extension API. The following new features are now available in the ATI Catalyst Control Center - Linux Edition Display Manager:

    - Display rotation
    - Multiple display arrangement and desktop sizing
    Also, not to forget, Linux 2.6.29/2.6.30 support as announced in last month's news post by Michael.

    The driver should be released tomorrow.

    That note about the primitive restart sounds a bit funky. If that list of extensions actually is getting in as new stuff and they get the support for two new Linux versions, I'd probably be impressed if I still used the closed drivers.

    Not really - it's probably something that won't concern most people (in other words, that bit on primitive restart isn't very funky), and actually might make things cleaner elsewhere. It's just a natural progression away from the whole client state enable/disable.

    I'll definitely be looking forward to the glsl 1.40 support.

    My definition of funky was that it's quite a bit different than what nVidia did even though it's originally nVidia's extension.

    Ah, gotchya.
    (btw, I'm damned tired as of writing this, but can't sleep until tried out new drivers!)
    I suspect ati would have done somthing similar if the opengl spec hadn't had some fairly drastic changes in that area. In any case, now that it's part of the standard, I'll be using primitive restarts in my terrain renderer.

    In other areas, no complaints about 9.8 so far. Still can't start amdcccle (something in my system really doesn't like that program), but otherwise it's all fine.

    I said I would forget about fglrx, but since this time it seems to support recent kernels and I've heard that Oblivion will be playable in wine with this version, I'm giving it a try. It seems to work ok with 2.6.31-rc6 (after re-exporting find_task_by_vpid). The performance is also good, but compositing is broken, as always (maximizing a window takes forever). And xv is also broken, as always (fucking washed colors).

    I'll try to play Oblivion. (edit) Nope, it doesn't work. In fact it RESETS MY COMPUTER after the game menu (it doesn't hang it, it resets it). Oh well. Back to the OS drivers.

    Those are legacy cards anyway both on Windows and Linux side. Only supported by older closed driver versions... (and open drivers)

    yeah, but there should be a release every 3-4 months, if I remember correctly

    I haven't heard of that, sounds interesting. Where'd you read it?
