A lightweight Rust-powered game performance optimizer — stable FPS, fewer stutters, lower input latency.
FPS Optimizer is a Rust utility that helps squeeze more frames out of your system and makes gameplay smoother. It applies safe system profiles, tunes process priorities, and reduces latency — without third-party drivers.
⚠️ All settings are reversible. A profile backup is created before any change is applied.
