PreySense is a lightweight Windows control suite for Acer Predator laptops. It replaces Predator Sense with a faster UI, deeper hardware control, and a bundled kernel driver for CPU/GPU power tuning.

Verified on Acer Predator Helios Neo 16S (PHN16S-71). Other Predator models may work.

Quiet, Eco, Balanced, Performance, and Turbo with one-click switching. Source profiles can differ for AC and battery. The Predator key (beside Num Lock) shows or hides the app; hold it and press 1-5 to jump modes. The chassis Mode / Turbo key still cycles modes.

Per-mode CPU and GPU power through the bundled PreySenseDriver:

• CPU PL1, PL2, Tau, and CPU Boost
• GPU Delta, Dynamic Boost, and platform power offset
• Optional global PROCHOT offset
• Factory calibration stored in preysense.json, with Reset to captured defaults
• Apply for a live test, Save to persist; saved profiles follow mode changes, startup, and resume when Enable Tuning is on

• GPU modes: Auto, Hybrid, Advanced Optimus, and dGPU Only
• Refresh rate control, Auto refresh rate to 60Hz on battery.

Per-mode Auto, Max, or Custom EC-style stages for Eco, Quiet, Balanced, Performance, and Turbo. CPU/GPU graphs set separate temps and duties; both fans run at the higher duty, with a shared 0–5 s stage delay. Fans keep running while the app is in the tray.

Automatically detected RGB devices, including supported per-key keyboards, four-zone keyboards, light bars, logos, and mode/turbo keys. The themed keyboard editor supports click, Ctrl-click, Shift-click, and drag selection; color changes apply automatically. Existing four-zone effects and logo sync remain available. See lighting support for compatibility and verification limits.

Always-on-top telemetry with selectable CPU/GPU metrics, optional graphs, FPS, GPU Clock, CPU Active Clock, and CPU Effective Clock, and CPU VID when the driver can read it.

• Charge limit (80% or 100%).
• Run on Windows startup, light/dark theme
• Languages: English, Simplified Chinese, Hindi, Spanish, French

• Windows 10 or 11 x64
• Acer Predator laptop
• .NET 10 Desktop Runtime x64
• Administrator privileges

1. Uninstall any previous PreySense version (required when upgrading from v2).
2. Download the latest PreySense.exe from Releases.
3. Run as administrator. Close official Predator Sense if it is running.
4. Closing the window hides to the tray; use Quit to exit.

Run on Startup is off when no scheduled task exists. It reflects this install’s enabled logon task (current-user principal, any interactive logon), not a JSON default. Existing enabled tasks are checked against the running executable and current launch settings; missing tasks and disabled tasks/triggers stay off until you enable startup. Logon launches minimized at HighestAvailable, without a delay, idle/network requirements, battery restrictions, or a runtime limit. Keep the executable in a permanent local folder. Registration failures are written to debug.log.

1. Open Tuning and turn on Enable Tuning.
2. Choose a mode, set CPU/GPU values, then Apply or Save.
3. Switch modes as usual; saved profiles follow automatically.

Settings → Theme offers Dark, Light, and Glass. Glass uses the Windows 11 Desktop Acrylic backdrop with translucent controls and applies immediately to open windows. Windows 11 build 22621 or later is required for the native backdrop; older Windows versions keep a readable solid dark surface. Dropdown popups share the control material tint. The choice is saved in General.Theme; existing settings without that field retain their LightTheme preference.
