  • Terrible Performance

    Hello everyone. I am having major issues with my AMD R9 380x in Ubuntu 16.10. I have great 2D performance, but anything 3D I get terrible performance. First, when I booted Ubuntu I had to do nomodeset and upgrade to the 4.9 kernel. Then I had to go and install the latest mesa from the padoka ppa. Other people keep saying this card is doing awesome in Linux but I have a hard time believing that. Here is everything I am running currently.

    AMD FX 8350 OC'd @ 4GHz
    AMD R9 380x 4GB
    Gallium 0.4 on llvmpipe (LLVM 5.0, 128 bits) <--- This is what "About Computer" says in Ubuntu currently.

    This is what lspci -vnn | grep VGA -A 12 outputs.
    01:00.0 VGA compatible controller [0300]: Advanced Micro Devices, Inc. [AMD/ATI] Tonga XT / Amethyst XT [Radeon R9 380X / R9 M295X] [1002:6938] (rev f1) (prog-if 00

    Here is my Mesa info:
    OpenGL version string: 3.0 Mesa 17.1.0-devel - padoka PPA

    Are you still running with "nomodeset" ? I believe that would explain why you are seeing SW rendering ("llvmpipe") rather than HW acceleration.

      I don't believe I am still running nomodeset. I haven't put in nomodeset since after installing Kernel 4.9 and installing the new mesa drivers.

        This place is for the proprietary driver and you are using the open source driver.
        Try this kernel:
        http://kernel.ubuntu.com/~kernel-ppa...ine/v4.10-rc7/
        You can also make a faster custom kernel,see:

          I know I put it in here on accident. I've tried Kernel 4.10RC7 and still ended up with the same issue. :-/

            OK, sparkzer has another thread in the open source area, let's move there:
