When running UFO test on Dynamic Window Manager it runs at 60 frames per second. Both in chromium and firefox. I have a 240Hz display. I use NVIDIA proprietary drivers.
After setting refresh rate to 240Hz with
xrandr, the cursor immediately becomes more fluent.
I also changed line 1116 of
if ((ev.xmotion.time - lasttime) <= (1000 / 60))
if ((ev.xmotion.time - lasttime) <= (1000 / 240))
It seems like it made moving windows around smoother. The UFO test still runs at 60FPS.
greping values like
16, but it seems the above was the only one.
I installed KDE on this system and immediately got 240FPS on the UFO test.
Could you please help me debug this issue?
What are your xorg settings? The time shown there is the time between motion notify events to move/resize windows, this is done for performance reasons and won’t limit your frame rate. dwm doesn’t limit the refresh rates of your monitor or the X server, so if you do
xrandr DisplayPort-0 -auto -rate 240
it should do the trick, just replace the display name with your own.
This can be made to run at login with shell scripts or an xorg config file.
Thank you for your reply. I tired this, but it did not resolve the issue. In chromium if I go to
chrome://gpu it says that my refresh rate is 239Hz, but UFO test (or any other web test) won’t go above 60.

You have any compositor (for example picom or compton) running in your dwm session?

Have you tried running the browser with
No idea if that would make a difference. My screen is a meagre 60Hz.
I am not sure if UFO Test is accurate in this case. I have a 120hz screen. UFO Test reports 60fps in xmonad (It reports 120 in Cinnamon though). However, vrrTest (Release Variance hotfix · Nixola/VRRTest · GitHub) reports 120. I am not too worried about UFO Test results unless you observed noticable frame drops.
@Head_on_a_Stick Thanks, but unfortunately it does not help
@chroot Thank you for linking that test. Everything works as expected there (I get smooth 240 FPS).
But I still noticeably get only 60 FPS in both Firefox and Chromium. I suspect there must be some parameter or variable that desktop environments set.
If I set
240 in Firefox it solves the problem. Default value for this variable is
-1. My best guess is that it means take system’s default. Any ideas how to change that default value?
Does anyone know what does preferred value in
xrandr do and how to change it? I have it set to
60 and is currently my only guess on what could be the issue.
