A Linux gaming enthusiast describes building a custom measurement device to quantify end-to-end input latency by simulating clicks and detecting screen response with a photodiode. The article focuses on comparing X11 versus native Wayland, VRR on versus off, and DXVK's low-latency fork versus default rendering behavior. It argues that many common gaming tweaks on Linux are hard to validate without hardware-based latency measurement.
