In the world of competitive esports, latency is the enemy. A delay of 20 milliseconds can be the difference between a headshot and a respawn screen. But latency is not a single number; it is a chain of events starting from your mouse switch and ending at your retina.

1. The Input Chain

GearVerify's latency tools isolate specific parts of this chain. When we measure "Input Latency," we are looking at the time it takes for the browser to register a `keydown` or `mousedown` event. This is heavily influenced by your USB polling rate (1000Hz vs 8000Hz) and your OS interrupt handling.

However, "System Latency" includes the render queue. If your GPU is at 99% usage, the render queue fills up, adding massive delay. This is why pros often cap their frame rates slightly below the GPU limit.

2. Measuring Frame Times

FPS (Frames Per Second) is an average. "Frame Time" is the truth. A game running at 60 FPS has an average frame time of 16.6ms. But if one frame takes 8ms and the next takes 25ms, the game will feel stuttery. GearVerify's frame time graph visualizes this variance (jitter).

3. High-Speed Verification

For true end-to-end measurement, you need external validation. Our lab uses high-speed cameras (1000 FPS) to physically measure the delay between a mouse click (LED indicator) and the screen reaction (muzzle flash).

"A 360Hz monitor is useless if your system latency is 40ms. The goal is to align the render pipeline with the refresh window."

4. Optimized Settings

To achieve the lowest scores in our Latency Lab:

  • Disable V-Sync: Classic V-Sync adds buffering layers.
  • Use Reflex/Anti-Lag: These driver-level features reduce the render queue depth.
  • Exclusive Fullscreen: While difficult in a browser, newer APIs are bridging the gap to allow exclusive-like performance.

Use GearVerify to baseline your system before and after applying these tweaks to confirm their impact.
