Gpu at 100% in games after some time

Ask Fedora
1

hello, i don’t know what is causing this but i’m posting it here as someone may help me

if i start my pc and start a game via steam everything is fine and i can get normal performances (like good performances) and everyusage (checked with the resource system monitor app) is normal but if i do other things (say like 30 minutes later or an hour later) when i fire a game performances are always literally bad, like some games drops fps from 180 to 20, and while i am in 20 fps i noticed the gpu is almost always at 100%. A reboot solves everything but it’s tedious and remains a problem.

i noticed that the process using 100% of my gpu is the game itself, so i thought steam was the culprit, but i updated the app in the meantime and nothing changed so it may be something else.

for the record i am on Fedora Workstation 41 and my system is a ryzen 7 cpu with a 6600 amd card, and is pretty fine to run most modern games at good fps with medium to high details

any hint?

any hint on that?kinda thinking about making a new installation

seems like it was the gpu drivers, i switched to mageia and then to fedora 42 and the issue is solved

4

mageia was not my cup of tea so returned to fedora after a few days, unfortunately till that date, i still have that problem…

any hint/suggestion?

@luca247 That sounds like the very issue I’ve been experiencing for a long time… Does your MCLK get stuck at 96 MHz? If so, it’s likely related to this one:

@rokejulianlockhart Would it be safe to assume you’re also affected? I’ve noticed your profile picture in the list of participants for the above issue.

@hasshu, I don’t think so:

RokeJulianLockhart@Beedell:~$ cat /sys/class/drm/card0/device/pp_dpm_mclk
0: 2800Mhz *
RokeJulianLockhart@Beedell:~$ cat /sys/kernel/debug/dri/0/amdgpu_pm_info
GFX Clocks and Power:
        2800 MHz (MCLK)
        600 MHz (SCLK)
        0 MHz (PSTATE_SCLK)
        0 MHz (PSTATE_MCLK)
        1355 mV (VDDGFX)
        1189 mV (VDDNB)

        625 MHz (PSTATE_MCLK)
        775 mV (VDDGFX)
        28.00 W (average SoC)

Rather, I accessed it via another, linked issue, and wanted to ensure that it didn’t regress, due to some reports with the 5700-series.
