03 · The Engine

A tuning engine
that runs while you play.

InputLag runs as a kernel-level engine underneath your game, adjusting IRQs, schedulers, power states, and network routes roughly 200 times a second to keep input latency as low as your hardware can physically go.

Click-to-photon, under 10ms.

Tunes the kernel, mouse polling rate, and display pipeline together, so your click shows up on screen faster than you can consciously notice it.

Smoother frame times, fewer spikes.

Smarter scheduling cuts stutter and frame-time spikes, so your worst frames land a lot closer to your average.

Tuned to your rig automatically.

Detects your hardware and the game you launch in seconds. No setup, no menus to dig through.

Picks the lowest-latency route.

Finds the network path with the least jitter using QoS rules, DNS prefetching, and packet prioritization.

A profile for every game you play.

Loved by people
who can feel a frame.

“Climbed out of an Immortal plateau a few weeks after I started running this. Hard to say how much is the tool versus just playing more, but my frame-time graph looks a lot steadier now.”

“I stream most days and used to fight random mid-session stutters. Haven't had one since I set this up. Can't promise it'll go the same for everyone, but it's been solid for me.”

“Ran the scan out of curiosity and it flagged a handful of background processes and driver settings I'd never have found myself. Audio felt noticeably snappier afterward. Small thing, but I noticed it.”
