Roblox FPS unlocker: Complete Guide for 2021

Like in every game, better performance and better fps are always appreciated, with no difference in Roblox. Roblox FPS unlocker is an unofficial tool that removes the fps lock in Roblox. This means that Roblox will not cap your FPS at 60 frames per second. But instead, it will go as high as your hardware can go.

Even though Roblox FPS unlocker is an unofficial tool, an official developer of Roblox created it, and it’s completely virus-free and safe to use on any device. Before we jump on how to install and use the FPS unlocker for Roblox, let me answer a few questions you might have before using it.
