Quick answer
Check Roblox’s built-in maximum frame-rate setting first. Third-party “FPS unlocker” downloads can be outdated or unsafe; GitHub popularity is not a security review.
Use the native setting
- Launch a Roblox experience on a supported desktop client.
- Open the in-game Settings menu and look for Maximum Frame Rate.
- Raise it only if your display and PC can benefit, then compare smoothness and temperatures.
Before considering an external tool
Roblox client updates can break unofficial tools. Do not run an unsigned EXE or grant administrator access on the strength of a repository name; inspect its current maintenance and official Roblox rules. A frame cap change cannot fix network latency or a low-end GPU.
If FPS is still low
| Symptom | Next check |
|---|---|
| GPU-bound | Lower Graphics Quality in Roblox settings. |
| CPU-bound | Close background apps and try a less busy experience. |
| Frame pacing uneven | Use a cap that the PC can sustain. |
