    Default floating point texture support....

    I have an old Acer laptop that I want to play a few older games on, but I can't because, (I think this is the problem, but not sure) I don't have floating point texture support.

    Running Archlinux with floating point textures enabled in mesa, with the i915 kernel module (old intel GPU). Could it be that my hardware simply can't do it? Or is there any hope?

    How should anybody know? You aren't telling us which GPU you are using. Do you get error messages about this feature?

    Oops, sorry about that...

    Truth is I don't know my GPU and I'm not sure how to find it out. Hehe...

    Was hoping all the i915s are the same or something.

    Yes there are error messages in games about shaders, sometimes textures. I have to disable texture compression for some of them to run (UFO AI). Crossover complains about floating point texture support specifically.

    If you run
    Code:
    $ dmesg > file.txt
    then it will create file.txt, containing a load of information about your system hardware, which will include your graphics card.

    If you run
    Code:
    glxinfo | grep OpenGL > another_file.txt
    as well, then we'll be able to see some more information.

    Nevermind, I just recompiled mesa with gallium support for i915 and everything is fixed and I can play all games.
