> If you require the absolutely lowest latency possible though and don’t care about screen tearing then X without compositing, with VSync disabled is a better fit for you. You can re-evaluate once the possibility to have VSync disabled is implemented in your compositor of choice and the measured increased volatility in latency (99th percentile) with immediate mode is fixed.

I enjoyed the post, thanks. I suppose I'll wait then and re-evaluate when Wayland's 'immediate mode' is fixed and it is roughly comparable to X11 without a compositor. I go to great lengths to minimize my latency so this is really the only factor that matters to me.
