Will RBX FPS Unlock get me banned?
The tool writes FastFlags to a config file Roblox already honors internally. It doesn't inject code, patch memory, or modify the game client—it's the same method used across the open-source FastFlag community. Check your game's rules before using any performance tools; RBX FPS Unlock makes no claims about account safety and doesn't defend against detection.
Can I switch back to 60 FPS anytime?
Yes. The Reset Flags button removes every change the tool made and returns Roblox to its default state in one click. Your game data stays intact.
Does it work on low-end PCs?
RBX FPS Unlock applies the flags, but whether your PC can actually sustain 144 FPS depends on your hardware. On weak machines, you may hit a ceiling before reaching your target frame rate—but the tool gets you as close as the config allows.
What if my monitor is 60 Hz?
You can still uncap Roblox to 120 or 144 FPS if you want smoother input response, even if your screen can't display all the frames. But if your monitor is capped at 60 Hz, uncapping the game won't visually show more than 60 frames per second on screen.
Do I need admin rights?
RBX FPS Unlock modifies files in your user folder, which typically doesn't require elevation. If Roblox is installed to Program Files or another protected directory, Windows may prompt for admin when you apply flags—this is normal.
Does it clean up cache automatically?
Yes. When you click Apply, the tool also purges Roblox cache files and temporary logs, freeing up disk space. It shows you how many MB were reclaimed.
Can I use it on multiple PCs?
Yes. RBX FPS Unlock is free and has no account system, so you can install it on as many Windows PCs as you own and use it the same way on each.
