I think i know what you are talking about, I had a similar problem with csgo in kde x11, disabling compositor fixed the problem, when compositor was on for some reason the game felt laggy even though it reported 300fps
Idk if you're already familiar with compositing (i.e. desktop effects) but having them on in any X11 desktop will hurt performance, much like what you're experiencing. Some DEs might have an option to disable compositing automatically when it detects a fullscreen-spanning window, but not all do.
In the case of KDE Plasma, there's a KWin script called Autocomposer, which fulfils that role perfectly (of disabling effects/compositing when something's fullscreen) - even when using multiple displays like I am, if a single panel gets filled, it'll still work. You'll notice because the other screen might flicker as transparencies and stuff get toggled off.
If you haven't tried it already (I'm assuming you didn't, just going by the original post), feel free to when you get the chance.
If nothing else, you've learned something new today.
Care to elaborate?

What do you mean by that?

Mh, can't confirm that at all. I nearly have the same frame rates on X and Wayland. But what usually helps me out here is GSync.
If your framerate is high but feels low switch to Wayland? Is that what you mean? Meaning, if your frame times are high Wayland can help with that?
Correct
Unless you are using nvidia GPU, I assume

Just disable your compositor so you can get direct scanout even on X11
TIL? You've gone over my head on this one
