GPU acceleration isn't always faster. Wayland is supposed to be faster because it utilises the GPU. Well, Firefox had the same idea with WebRender. Now, when I scroll on my poor laptop's Intel HD 4000, both Firefox and Wayland are fighting over GPU resources resulting in less FPS compared to X11. The CPU is almost idle. 😅

@fell that's a two part issue firstly the Firefox issue, as it locks the fps of the browser to 60, change it using layout.frame_rate in about:config

Then this also could be caused by Intel's dumpster fire drivers, consider setting the DPM of your card to high instead of auto.

@mah I just noticed that the performance is near-perfect in Weston. Maybe it's a KDE issue. I wouldn't be surprised if the Plasma Wayland stuff still has a few rough edges.

@fell it's still awful, as cruel as it sounds, there are issues I experienced over a year ago that are still there, not to mention that 6 has been a complete bust for a lot of people.

When I want to experience Wayland, it's either with Hyprland or GNOME for me.

But do make the change I mentioned for Firefox, it will help tons.

@mah I did set layout.frame_rate = 60 but it did not change much. It's still very stuttery.

@fell no change* it to your refresh rate*, so if you're on 75, 90, 144 etc, set it to that.

@mah Looks like this is the bug: https://bugs.kde.org/show_bug.cgi?id=452119

@fell yeah Intel drivers aren't great, setting the DPM for it to high can help this though, at the cost of battery life.
