How to get 144hz working on desktop

[PickleTickle]

Currently I have one monitor plugged into my motherboard and 2 into my GPU (all of them are displaying fine).
The GPU monitor is set to 144hz but moving windows around etc. is clearly at 60hz. I added xrandr output below

Maybe you could make use of a similar version of

Lots of display problems after installation of Manjaro KDE (Lysia)

Does the whole display crash? If that (was) the case … it may not be any more after you have sorted out your drivers and such. That said … its possible that maybe you could still access TTY (ctrl+alt+f2,3,4,5,etc) Also… I could tweak the command to go a bit more like this maybe. (ok I kinda gave up at the end … because I didnt start out to write a script ) mimon=$(xrandr | grep " connected" | cut -d' ' -f1); ores=$(xrandr | awk -F'[^0-9x]*' '/*/{print $2}'); or…

(I am sorry I dont feel like editing it right now … it was initially created with the assumed known that there is a single display device … but you should be able to scrape the basics)

ah I should have mentioned I was using xfce. My display and everything suggests that I’m using 144 hz and I’m starting to question whether it’s just the UI being really stuttery but actually displaying at 144hz. Not really sure what to do to check if that’s the case though.

Testing on the UFO test and minecraft it seems like I’m getting the desired refresh rate. Lutris games seem to be stuck at 60hz but I think that’s a separate issue.

Yes sorry, the above certainly uses plasma tools, and I didnt mention it.
(though … making it was the first time I used those plasma tools … it was first being made for xrandr and can pretty quickly be adopted for//instructive of that method as well)

Hm.
Without access to an XFCE system its a bit difficult for me to double check.

But a few things come to mind.

First - compositor. (check turning it off … xfwm compositor is … weird)

Second (and mainly) - generally systems are set at 60 by default. (insert my long story here)
[check running glxgears vs vblank_mode=0 glxgears]

… I guess at this point I am wondering if you need pointing to the similar xrandr commands … or pointing towards the wiki for ‘manually adding and using display resolutions’

[PickleTickle]

Before turning off the compositor, here’s what I get from glxgears.

3 monitors on - 60fps
Removing my non-144 hz monitor - 144fps
Removing both monitors (except 144 hz one) - 144fps

Using vblank_mode=0 glxgears I get the same result as above.

With __GL_SYNC_TO_VBLANK=0 glxgears I get uncapped frame rate on any combination (20,000+ fps).

The stuttering happens whenever I have the compositor enabled.

If I have it disabled, the stuttering happens when I move a window that is overlapping google chrome in the slightest.
If I make half the screen a window (e.g. terminal) and move a window over terminal, there’s no stuttering. Moving google chrome itself around is fine (unless it’s overlapping another chrome window).
