Finally got to ~zero input-to-display latency on macOS. It has taken us a _lot_ of work to get here! This is a slow-motion capture of a 120 Hz screen running a playbit program that draws a rectangle where the cursor is. The slight lag you're seeing is not from rendering latency but from "old" mouse position data (we receive it from macOS window server in a event queue.) Remember that the mouse cursor is drawn with dedicated hardware (dedicated GPU plane) so dragging a rectangle is the ultimate input-to-display latency test.
