best I can tell there is no Wayland support in Budgie in Solus yet. I don't see a way to switch anywhere on Solus posts.
Worth noting I'm able to play games just fine (games use the GPU and run well, not using the iGPU). Haven't played enough to see what happens if I get the slowdown while playing a game.
