X11 vs Wayland cursor latency
X11 vs Wayland cursor latency
I don't think he should have included the starting frame-- if the cursor were theoretically instant, his method records it with a 1 frame delay, and this +1 frame error happens on every test. Correcting this actually makes Wayland more laggy proportionally, although it makes both less laggy absolutely.
What I've noticed with Wayland in Plasma is that it's very much tied to my monitors refresh rate.
At 240Hz, with adaptive sync turned off or to Automatic, I get a very responsive cursor.
At 75Hz, or if I force adaptive sync to be on at all times (instead of off or Automatic), then I get a noticeable mouse latency
I saw some cheap laptops with Ubuntu in a local mall and on them the latency on Wayland was unbearable.
I'd be very interested in sway and hyprlands numbers
