    Hi,

    which graphic card is best for big PA matches?
    I would like to have full shadows, full textures, and stable high fps with 4k under linux. Prefering AMD.

    currently with a medium old graphic card, sometimes I end up with about 8 fps. Still playable, but could be better.

    I am prefering AMD.
    Any suggestion what is important?
    High memory is probably not important?

    edit: I'll just get a rx 580 and tell the results here...

    Personally for PA I would avoid AMD. The driver support for opengl has been pretty slow and bad over the years. Maybe they are in a better place now.

    I received my AMD rx 580 now. Before testing, i updated my Ubuntu LTS 16.04 to Ubuntu LTS 18.04. I am using the free radeon driver, i think. result:

    Moire artifacts sometimes on textures, some texture areas missing/broken. My Firefox rendering is bugged and slowed sometimes... so I will need experimenting with drivers a bit. I will tell you more results and suggestions then.

    I upgraded to Ubuntu 18.10 testing version. But this version broke my sound for PA. Haven't found a workaround for it, yet.

    Anyway, by using updated open source drivers from a ppa, the performance of PA increased. Nevertheless, there is still the use-after-free-bug, which causes wrong textures to be printed often. But its okay to play for me for now.

    Here is the ppa for ubuntu I used: https://launchpad.net/~oibaf/ archive/ubuntu/graphics-drivers

    My settings now:
    AMD RX 580, i5, 16GB-Ram, 4k

    PA settings:
    Virtual Textures: High
    Light: Uber
    Shaddow: High
    Environment-Darkening: Off
    Anti-Aliasing: Off
    HDR: On
    Resolution: 100%
    Mode: Fullscreen

    Running this as root improves performance:

    echo "high" > /sys/class/drm/card0/device/power_dpm_force_performance_level

    and switch back to automatic power management after finishing the game:
    echo "auto" > /sys/class/drm/card0/device/power_dpm_force_performance_level
