I’ve recently got a FreeSync monitor and am still figuring out how to get VRR (variable refresh rate, or “adaptive sync”) to work consistently.
I’d love to hear your experience with VRR.
Some of my tests:
Sway
In sway, I set adaptive_sync on for my display, and swaymsg -t get_outputs reports Adaptive sync: enabled
- Unfortunately, by default stuttering in games is present
- To fix, I had to use
sway -Dnoscanout. Apparently, this has its drawbacks. - Even with
-Dnoscanout, moving the mouse breaks VRR and causes stuttering
Hyprland
In hyprland, I set vrr = 1 and get similar results as sway -Dnoscanout
- Fluent motion by default, but moving the mouse introduces stuttering
Gamescope
In gamescope (embedded from VTT, with --adaptive-sync), I get the best results yet
- Stable fluent motion
- Mouse doesn’t break it
My setup is 6600xt, Gigabyte M28U monitor, Arch 6.1.64-1-lts. I test with vrrtest and with Ghostrunner on wine-tkg-staging-fsync-git 8.13.r7.gc210ef9f-327
On sway it works fine for me except in fullscreen Xwayland apps, so that’s all of my games.
Plasma Wayland works flawlessly and I use it daily for gaming.
Plasma X11 works only in fullscreen apps and with one screen only, and it requires custom X.org configs.
If you run Wayland then you have to use KDE because VRR does not work on GNOME
Currently none, because I’m using the forbidden combination of Nvidia GPU + multiple monitors.
Thankfully most of the games I play are lightweight and can run at a constant 120FPS, but for any demanding game it’s back to Windows.
Work fine for me on plasma wayland. Even the system settings has an option for it
