FPS Booster & Lag Fix for Windows — 2026
A lightweight, open-source Windows utility designed to optimize Roblox performance. Boost your frame rate, fix stuttering, reduce input lag, and unlock custom frame limits without modifying game files.
Roblox Performance Tool is a native utility for players who want smoother gameplay. It safely adjusts system priorities and removes the default frame rate cap, which causes stuttering and input delay on modern monitors.
🛡️ Safe by design: It does not inject code into the game, does not modify memory, and does not bypass anti-cheat. It only adjusts the frame rate limit and system priorities.
