General information:

• I’m using EndeavourOS, with KDE Plasma. I am very happy with my setup as it is, but since Wayland is “the future” I’m thinking of getting a move on.
• It came default with just X11, no Wayland. I know KDE supports Wayland but have no idea how to switch.
• I play a lot of games, I read somewhere that Wayland has worse gaming performance. I don’t know if true or not, though.
• … I have an AMD GPU. I’m not enough of a masochist to try and use Linux with NVidia.
• … BUT I’ve been thinking of upgrading to an Intel Arc GPU in the nearish future.

Let me know if there is any, more important, specific info I should be giving.

EDIT: I have changed. … I felt no difference, but I suppose that is the whole point. Thank you to everyone who answered.
