I'm not an expert on the wayland/xorg/xinput/gnome-shell stack, but unless someone smarter takes good measurements of various things (visual and input delays), I'd suggest 1). Xorg + gnome-flashback or Xorg + other non-compositing WM or 2). Non-gnome compositor under wayland As for 1). Xorg b/c it can provide pointer movements at ~native speed via xnput vs Gnome/Wayland 60-240Hz. And gnome-flashback b/c it's a non-compositing WM, so there's no frame buffering (unless you enable it in nvidia's panel, or via TearFree in amdgpu). As for 2). Sway, I suppose, doesn't aggregate mouse movements, but looking at https://zamundaaa.github.io/wayland/2021/12/14/about-gaming-on-wayland.html https://zamundaaa.github.io/wayland/2021/12/14/about-gaming-... the author used some hack to enable "immediate" "drawing" under KWin. I'm not sure what's the default behavior of e.g. Sway - does it buffer frames?
