Little misconception here (beware i'm using xlibre and causal user). On X11 you can find two mechanisms which can be called compositor :

1st: "enable display compositing" option - this one increases latency as every window draw need go though compositor application (in nutshell it exchanging opengl textures - only synchronization messages goes over "wire")

2nd: the Xserver rendering pipeline compositor, this one goes with modesetting (intel, amdgpu) driver TearFree option - almost everything inside X11 server in OpenGL textures and compositor perform direct blending to screen (including direct scanout).

What I want to tell, on modern X (there are merge requests for Xorg server to modesetting driver, amdgpu have this code) with TearFree enabled you by default optimal hardware acceleration - there comes lower latency
