Every millisecond of precision is our respect for players.
I'm an independent game developer and a long‑time gamer.
While building game input systems and testing hardware response,
I often ran into issues like unresponsive keyboard keys,
erratic mouse double‑clicks, dropped clicks, dragging failures,
and unstable scrolling. The worst part? I could never be sure
whether it was actually a hardware problem with the mouse or keyboard.
To isolate the issue, I needed a clean, distraction‑free testing environment —
so this website was born.
