Real measurements, never simulated.
Every reading comes from real sensors and APIs on your machine — never a placeholder or a guess.

PULSE · About
A precision instrument for your PC.
PULSE is a game performance optimizer for Windows. Our mission is to make every game run faster and smoother — guided by real measurements, and undone with a single click.

Mission
Performance you already own.
PULSE exists to unlock the performance already sitting inside your PC. Every value it reads comes from real hardware sensors, every adjustment is tuned automatically, and every change is fully reversible. No guesswork, no bloat.
The rule
A tool that touches your machine should earn your trust before it earns your frames.
So PULSE shows its work, records the original state before it changes anything, and hands the keys back the moment you want them.
The principles
Four principles. Non-negotiable.
Not slogans — constraints the product is built around.
100% reversible.
Every change is recorded before it's made, so one click puts your system back exactly as it was.

PULSE operates outside your games — no kernel driver, no memory injection, nothing to trip a fair-play system.

Built in RustHow we measure
Real sensors. Zero simulation.
CPU usage, GPU temperature, RAM speed, FPS, frametime, network ping — all from real hardware sensors. No simulated values, no estimates.
When a sensor doesn't exist on your machine, the reading shows an honest “—”. A dash tells you the truth; an estimate would tell you a story.
The same rule covers our numbers. 15–45% more FPS on many CPU-bound games is the honest range — gains vary by game and hardware, GPU-bound titles see less, and every performance chart we publish is labeled illustrative, because that's what it is.
