With a more sensitive light probe, I can now take full-screen measurements for input lag, which is great for capturing the very first pixel response based on a keypress or mouse movement!
I covered framerate limiters in the last video, but how do you really minimize input lag? This video seeks to answer that by looking at V-Sync Off, GPU utilization, and NVIDIA's Reflex tech. I cover my old standbys, ezQuake and Quake 2, but I measure some modern, competitive games as well: Quake Champions, Destiny 2, Call of Duty: Warzone, and Apex Legends.
