After playing Path of exile 2 for a while Freesync seem to eventually bug out and get monitor stuck at 28 hz, changing displays hz afterwards to anything above 60 hz just keeps it stuck at 28 hz, only restarting pc /changing to another user and then changing back again resets it back to 165 hz

I tried:

  • /etc/X11/xorg.conf.d/20-amdgpu.conf
    Option “VariableRefresh” “false”

Does not actually work

  • adding the game(Path of Exile 2) executable to /usr/share/drirc.d/00-mesa-defaults.conf with

Did manage to disable freesync once on game launch, but then i could not reproduce it

Compositor is disabled
Freesync can’t be disabled in Monitor OSD settings

This?

xrandr --output HDMI-A-1 --set "freesync" "off"

https://www.amd.com/en/resources/support-articles/faqs/GPU-754.html#gpu-754-enabling-freesync

3

that doesn’t work either
xrandr --props
doesn’t list freesync as a property as well

4

Well, then your monitor is not capable of freesync. Therefore, freesync is most likely not the problem, since even set in the options the monitor is not able to do so.

5

i didn’t have any issues that one time when game launched with freesync off in monitor ocd

BenQ EX240 is absolutely capable of freesync

6

Could it be that freesync is not support via HDMI on linux anyway? So only DisplayPort is supported?

That could explain why freesync is not listed at the props of xrandr.

7

Some displays which implement (part of) the HDMI 2.1 specification also support VRR over HDMI. This is supported by the Nvidia driver and is supported by the AMD driver (pre HDMI 2.1) in Kernel 5.13 and later [17].

Point is, even if it doesn’t work properly it still causes issues
When monitors ocd does show that freesync premium is on, then Poe 2 sometimes buggs out monitors refresh rate, monitors osd shows 28 hz

When monitors ocd had freesync off, then everything was smooth
