Tuning Framerate Limit / FPS Unlocker (DFIntTaskSchedulerTargetFps) for your Windows hardware
Every Windows PC responds differently to Framerate Limit / FPS Unlocker (DFIntTaskSchedulerTargetFps). On integrated Intel UHD / Iris Xe or AMD Radeon Vega laptops, conservative settings keep GPU load under 90% and prevent thermal throttling.
On dedicated NVIDIA GeForce GTX/RTX and Radeon RX desktops, pairing `DFIntTaskSchedulerTargetFps` with a matched framerate cap in Engine Settings delivers the flattest frame-time graph.
How to apply and benchmark in 60 seconds
- Open **Bloxstrap Menu** (install from /download if needed) and go to **Engine Settings → Framerate limit**.
- Select your target value from `144, 165, 240, 360, or 0 / 9999 (unbounded)` and click **Save**.
- Press **Shift+F5** inside Roblox to open the native microprofiler FPS readout and verify your frame time in milliseconds.
