G-Helper for the ROG Ally
G-Helper supports the ROG Ally and ROG Ally X alongside the Asus laptop lineup. On a handheld, where battery and thermals matter more and every running service costs frame time, the trade is straightforward: same hardware control, much smaller footprint, plus two features that matter specifically on a handheld.
AutoTDP
Set a target FPS and G-Helper continuously tunes TDP between 6 W and your mode’s ceiling to hit it. On many games this gives you the same FPS at noticeably lower power, which on a handheld means longer battery, less heat, and a quieter device. Nothing to fiddle with between scenes or menus.
Quieter fan profiles than the stock options
G-Helper lets you set fan curves below the floor the firmware ships with. For light indie / 2D titles, emulation, or media playback, the Ally can run effectively silent at ranges where Armoury Crate SE would still spin up. This is the change most Ally owners feel right away.
The rest of the controls
- Per-mode TDP / power limits for Silent, Balanced, Turbo, and Manual.
- Battery charge limit. Cap charging at 80% so the pack doesn’t sit at full while docked.
- Auto-switch performance mode on battery vs. AC. Battery → Silent, dock → Turbo, or any combination.
- Hotkey rebinding for the M1 / M2 macro buttons.
- Visual modes and refresh rate control. Drop to 60 Hz on battery, push max Hz when docked.
- One tray app, no services.
Why people switch from Armoury Crate SE
Same reasons as on a laptop, sharper because of handheld constraints. A single 5 MB .exe instead of a multi-component install with services. Less RAM and idle CPU between sessions, less interference with the games themselves. Native window, opens fast. Updates are optional and reversible, with older versions kept on GitHub if you ever want to roll back.
If you actively use AC SE’s Game Library or per-game Scenario Profiles, those don’t have direct equivalents in G-Helper. Full breakdown on G-Helper vs Armoury Crate.
Setup notes for Ally / Ally X
- G-Helper needs Windows and .NET 8. The ASUS System Control Interface driver is pre-installed on every ROG Ally from the factory, so there’s nothing extra to set up. Full prerequisites are on the Requirements page.
- G-Helper can run alongside Armoury Crate SE briefly while you decide. To switch fully, uninstall Armoury Crate using the official Asus tool. Reversible.
- After a clean uninstall, the popup that asks you to reinstall AC sometimes comes back. Fix is at How to stop the Armoury Crate install popup.
Compatibility
