AMD's OverDrive and CrossFire Come To Linux 82

twljagflba writes "Since last year AMD has made ATI increasingly Linux friendly by releasing 3D programming guides and helping out the open-source community. At the same time they have been continuing to develop their binary Catalyst driver for the Linux platform and most recently they delivered same-day support for their new graphics cards. Today though they have released the Catalyst 8.8 Linux driver that adds two very important features: CrossFire and OverDrive support for Linux. Linux users are now able to use CrossFire to split the rendering workload between multiple GPUs and they're also able to overclock their graphics cards now using the binary-only driver. Phoronix has a complete run-down on both features — including benchmarks — in their AMD OverDrive on Linux and ATI Radeon CrossFire On Linux articles. Other features were also introduced in this update such as Linux 2.6.26 kernel support, Adaptive Anti-Aliasing, and other fixes."

    I've got to say I'm disappointed they don't provide Crossfire numbers for the same hardware on Windows. It's nice that Crossfire can improve things in some situations and some games that are supported under Linux, but I'd like to know the relative benefit.

    That is, when going to Crossfire do both Windows and Linux gain 40 FPS? Or do they both go up 60%? Or does Windows go up by 70% to 100 FPS where Linux only goes up 40% to 80 FPS?

    How close are they? That's what I'd like to know.

    I also find the "we had no problems except for some segfaults during Quake Wars, and they say that will be fixed in a month or two with the next version" a little worrying. A problem with a driver is a game looking off, or having slow frame rates. Segfaulting the system is not a problem, it's a BIG PROBLEM.

    • did it say the /OS/ segfaulted? I'm pretty sure I had apps segfault in Linux without taking the OS down with them. Admittedly it's been a while since I've used Linux (about a year?), so I can't remember for certain.

          Being built as a module makes it no different from an in-kernel driver once it is loaded. A crashing driver would have the same effect whether it's a module or not.

        • True, if the video driver segfaults, it'll only take down the display. You won't be able to see anything, but other than that, the system will be fine.
          • If you are logged in via kdm/gdm/xdm, it will also log out (at least in FreeBSD, the intel driver on my notebook has done that to me a couple of times in an older version of xorg).

            Still, that's annoying, not a system crash.

And whether someone will buy nVidia, Intel or ATI graphics for Linux depends upon their preference for powerful but proprietary binaries, free software compositing and low power consumption or the choice of reasonable performance in ATI's binaries or high-performance free software from the X.Org drivers.
