[SOLVED] Dirt rally (Phenom x6 + RX 460)

Hi

Has anyone managed to get the game working correctly on arch using amdgpu opensource drivers?

My config

  PROCESSOR:          AMD Phenom II X6 1055T @ 2.80GHz (6 Cores)
    Core Count:       6
    Extensions:       SSE 4a
    Cache Size:       512 KB
    Microcode:        0x10000dc
    Scaling Driver:   acpi-cpufreq schedutil

  GRAPHICS:           MSI AMD Radeon RX 460 2048MB
    OpenGL:           4.5 Mesa 17.0.2 Gallium 0.4 (LLVM 3.9.1)
    Display Driver:   modesetting 1.19.3
    Monitor:          2963
    Screen:           2560x1080

  MOTHERBOARD:        ASUS M4A88TD-V EVO/USB3
    Memory:           12288MB
    Chipset:          AMD RS880
    Network:          Realtek RTL8111/8168/8411

  DISK:               2 x 500GB Western Digital WD5000AAKS-0 + 64GB KINGSTON SNV425S + 63GB SanDisk SDSSDP06 + 2000GB Expansion Desk
    File-System:      ext4
    Mount Options:    data=ordered relatime rw
    Disk Scheduler:   CFQ

  OPERATING SYSTEM:   Arch Linux
    Kernel:           4.10.6-1-ARCH (x86_64)
    Desktop:          KDE Frameworks 5
    Compiler:         GCC 6.3.1 20170306

Menu are so sluggish that it is barely usable to navigate even if CPU&GPU do not look max out.
Performance in games are inconsistent between resolution (some higher resolution gives more fps at same preset)
At the beginning of the game I get warning that my distribution/hardware does not meet the minimum requirements ... not expecting max out resolution but some intermediate/low settings/resolutions should be possible.

Wondering if the desktop resolution (pretty high at 2560x1080) has an influence? need to check ....

Any direction to dig into?

Progressing ....
This is my baseline for performance

For the cpu not maxing out I will dig more deeper in that direction
https://wiki.archlinux.org/index.php/CP … cy_scaling

And check the bios at the same time ...

Any other hint?

Maybe you should try the radeon driver https://www.phoronix.com/scan.php?page= … deon&num=1

What driver are you referring to?

The one I use is this one
https://www.archlinux.org/packages/?nam … deo-amdgpu

Same as tested in Phoronix article.

Re: [SOLVED] Dirt rally (Phenom x6 + RX 460)

Found something weird with cpupower

analyzing CPU 0:
  driver: acpi-cpufreq
  CPUs which run at the same hardware frequency: 0
  CPUs which need to have their frequency coordinated by software: 0
  maximum transition latency: 4.0 us
  hardware limits: 800 MHz - 2.80 GHz
  available frequency steps:  2.80 GHz, 2.20 GHz, 1.50 GHz, 800 MHz
  available cpufreq governors: performance schedutil
  current policy: frequency should be within 800 MHz and 2.80 GHz.
                  The governor "performance" may decide which speed to use
                  within this range.
  current CPU frequency: Unable to call hardware
  current CPU frequency: 2.80 GHz (asserted by call to kernel)
  boost state support:
    Supported: yes
    Active: yes

If I believe the wiki this is not the correct module load for phenom, it should be powernow-k8!

**** EDIT ****
My mistake :-(
CPUFreq driver for K8/K10 Athlon 64/Opteron/Phenom processors. Since Linux 3.7 'acpi-cpufreq' will automatically be used for more modern CPUs from this family.

Using

sudo cpupower frequency-set -g performance

has fixed the problem  and the game is now playable!
