How Framerate Limit / FPS Unlocker (DFIntTaskSchedulerTargetFps) works in ClientAppSettings.json
Sets the native Roblox task scheduler framerate ceiling without external DLL injection or memory tampering.
When you adjust **Engine Settings → Framerate limit** inside Bloxstrap, the bootstrapper writes `DFIntTaskSchedulerTargetFps` into `ClientSettings\ClientAppSettings.json` before `RobloxPlayerBeta.exe` initializes its renderer.
Recommended values and stability tips
- **Accepted values:** `144, 165, 240, 360, or 0 / 9999 (unbounded)`. Stick to the built-in GUI preset under Engine Settings unless you are testing a specific JSON override.
- **Resetting:** If a custom value causes visual artifacts or a startup crash, use Reset FastFlags to default.
- **Installer:** Download the latest Windows build of Bloxstrap from /download.
