Roblox ships capped at 60 FPS regardless of your monitor. GuIltyHub sets the cap to whatever you want — 144, 240, 360, or a number you type — by editing Roblox's own settings file. No injector, no DLL, nothing attached to the game.
Any cap you want
One-click presets for 30, 60, 120, 144, 240 and 360, plus a box to type your own. Match your monitor exactly instead of picking from someone else's list.
No injector, no DLL
Most FPS unlockers attach to the running Roblox process. GuIltyHub writes to Roblox's own ClientAppSettings file instead — nothing hooks the game, so there's nothing for anti-cheat to object to.
Cap down, not just up
Uncapping isn't always what you want. Running a dozen clients at once, an uncapped GPU cooks itself — set 60 or 30 and keep temperatures sane.
Applies to every instance
The setting is read by every Roblox client that starts afterwards, so it works the same whether you launch one account or twenty.
Finds your install automatically
Roblox scatters version folders and moves them on every update. GuIltyHub locates them itself and tells you how many it found — no hunting through AppData.
Part of the manager, not a separate exe
It comes with the account manager rather than as a standalone download, so there's one signed-in app to trust instead of a random unlabelled binary from a forum post.
Honest comparison vs the obvious alternatives.

Download freeGuIltyHub changes a Roblox setting file rather than injecting into the running game, which is the approach Roblox itself exposes through FFlags. It doesn't modify game code or memory. That said, no third-party tool can be guaranteed safe forever, and you use it at your own risk.
The default client targets 60 FPS regardless of your monitor's refresh rate. On a 144Hz or 240Hz display that leaves most of your hardware unused, which is why unlockers exist.
Yes. Roblox reads the setting when a client starts, so anything already running keeps its old cap until you relaunch it. GuIltyHub reminds you at the point you change it.
The unlocker looks for Roblox's version folders, which only exist once Roblox has been installed and launched at least once. Start Roblox normally, then reopen the page.
Yes. The setting applies to every client launched afterwards. If you're running many at once, consider capping lower rather than uncapping — GPU load multiplies per client.
Yes, on the free plan, along with multi-instance launching, auto-relaunch and the server browser. Paid tiers raise the instance cap; the FPS unlocker isn't gated.
