The ROG Ally X ships from ASUS with conservative defaults — safe settings that protect the hardware but leave performance on the table in some scenarios and drain your battery faster than necessary in others. Five targeted changes transform how the device performs in practice, and they take under ten minutes to apply. This guide covers every setting that matters, starting with the one that affects every game you’ll ever play.
If you’re new to the device, our ROG Ally beginner’s guide covers the hardware and software setup first. If you already know the device and want the optimal configuration, start here.
Set Your TDP First — Everything Else Flows From It
TDP (Thermal Design Power) is the maximum amount of power the ROG Ally X’s APU is allowed to consume. The higher the power limit, the more performance you extract from the Ryzen Z1 Extreme’s 12 RDNA 3 compute units — but also the faster the 80Wh battery drains.
The Ally X has four operating modes accessible via the Command Center button on the left side of the device [1]:
| Mode | TDP | When to Use |
|---|---|---|
| Silent | 13W | RPGs, card games, visual novels, turn-based games |
| Performance | 17W | Most games on battery — the default handheld mode |
| Turbo | 25W | Demanding AAA on battery when you need more headroom |
| Turbo+ | 30W | Plugged in only — absolute maximum output |
Performance mode at 17W is the right default for most handheld sessions. At this TDP, the Z1 Extreme delivers enough headroom for Cyberpunk 2077, Elden Ring, and most AAA titles at 1080p with FSR enabled — and the 80Wh battery holds roughly 3 to 3.5 hours. Jump to Turbo at 25W and you gain 15–20% more frame rate in GPU-limited games, but battery life drops to around 2 to 2.5 hours.
Silent mode at 13W is more useful than it looks. For strategy games, RPGs, indie titles, and anything that isn’t GPU-bound, Silent delivers adequate performance while extending battery life to 4+ hours. The fan runs quietly or inaudibly in most non-demanding titles.

To switch modes: press Command Center → tap Operating Mode → select your target. Changes take effect immediately without restarting.
Manual mode gives you SPL (Sustained Power Limit), SPPT, and FPPT sliders for fine-grained tuning. FPPT sets maximum burst power for up to 10 seconds, SPPT holds up to 2 minutes, and SPL is the indefinite sustained ceiling. Most players won’t need manual mode, but an SPL of 18W with FPPT at 20W is a practical sweet spot between Performance and Turbo for extended battery sessions in demanding games [4].
VRAM Allocation — Change This Before You Launch Anything
The ROG Ally X ships with 24GB of LPDDR5 RAM, and a portion of that can be reserved as VRAM for the GPU. The factory default allocation is too conservative for modern 3D games — many titles now require 6GB or more to run without stuttering or texture errors.
How to change it: Armoury Crate → Settings → Operating Mode → GPU Settings → Memory Assigned to GPU. Reboot after changing — allocations don’t apply mid-session.
For the ROG Ally X specifically:
- 6GB: Safe baseline for most modern 3D games. Resolves stuttering and launch failures in titles like God of War, The Last of Us, and Cyberpunk 2077.
- 8GB: Better for demanding AAA games at high settings. The Ally X’s 24GB total makes this viable without starving the OS — the original 16GB Ally X struggled at 8GB, but the Ally X handles it without issue [2, 3].
One exception: CPU-heavy simulation games — city builders, grand strategy titles, Dwarf Fortress — benefit from keeping VRAM at 6GB. High VRAM allocation in CPU-bound titles can reduce system RAM headroom and introduce stuttering in the opposite direction [2]. For a deeper explanation of why VRAM matters on unified memory hardware, our game settings explained guide covers the mechanism.
FPS Limiter and Display Refresh — The Battery Double Play
Two settings — the FPS limiter and display refresh rate — work together to extend your battery life more than either does alone.
FPS Limiter
An Armoury Crate SE update added a 40 FPS cap option alongside the existing 60 FPS limit [6]. The 40 FPS figure was chosen deliberately: it divides evenly into the 120Hz panel’s refresh cycle, producing even frame pacing without screen tear or VRR judder. At 40 FPS in Performance mode, most demanding games become consistently playable while consuming significantly less GPU power than targeting 60.
How to set it: Command Center → FPS Limit → select 40, 60, or Off. Requires exclusive fullscreen mode in-game.
- RPGs, strategy, slower-paced games on battery: 40 FPS cap + Performance mode = longest session time while staying fully playable
- Action games and shooters: 60 FPS cap or Off + Turbo when plugged in
- Indie and 2D games: Silent mode, no cap needed — these titles rarely tax the GPU
Display Refresh Rate
The Ally X’s 1080p IPS panel runs at 120Hz by default. Dropping to 60Hz — accessible via Windows Display Settings → Advanced display → Choose a refresh rate — meaningfully reduces power draw from the panel. For single-player games where motion clarity at 120Hz doesn’t provide a practical benefit, 60Hz on battery is worth enabling. Keep 120Hz for competitive titles and anything you’re playing plugged in.
Getting the right settings makes a big difference — see cyberpunk 2077 rog ally for the optimal config.
AMD Upscaling — FSR In-Game and RSR as a Fallback
Upscaling renders the game at a lower internal resolution and reconstructs it at 1080p, recovering significant GPU headroom. The ROG Ally X supports two AMD upscaling paths that serve different use cases [1]:
FidelityFX Super Resolution (FSR) — in-game, per title
When a game’s graphics menu includes FSR, enable it. FSR renders internally at a lower resolution (typically 720p) and uses temporal algorithms to output 1080p. Quality mode is the best starting point — you’ll recover 20–40% more FPS depending on the game, and the visual difference from native rendering is minor on a 7-inch display at handheld distance. FSR is the better option when available because it’s implemented per-game with developer tuning.
Radeon Super Resolution (RSR) — global, no in-game support needed
RSR applies upscaling at the driver level to any game running below native resolution, regardless of whether the game has FSR support. To enable: launch the game in fullscreen → set resolution to 720p or 900p → exit → Command Center → toggle AMD RSR on → relaunch. It’s a blunter tool than in-game FSR but extends upscaling coverage to older and unsupported titles.

Battery Care Mode and Charging Health
The ROG Ally X uses a 4-cell 80Wh lithium battery — the largest in any Windows handheld at its launch. Protecting long-term capacity matters.
Battery Care Mode limits charging to 80% and is accessed via the MyASUS app → Customization → Battery Care Mode. If you mostly game at a desk with the Ally X plugged in, enable this — repeatedly charging a lithium cell to 100% accelerates degradation over time [2, 5].
The capacity trade-off is straightforward: 80% of 80Wh gives you 64Wh effective. For stationary play, you’ll never notice the difference. Disable it before travel or whenever you need full range.
Armoury Crate Profiles and CPU Boost
Armoury Crate SE supports per-game profiles that automatically switch TDP, FPS limits, and operating mode the moment you launch a title. Around 40 popular games — including Call of Duty: Warzone, Forza Horizon 5, and Hogwarts Legacy — have pre-built optimization profiles included [6].
Access via Armoury Crate → Library → select a game → Operating Mode → configure your profile. Custom profiles save automatically and activate on next launch.
CPU Boost
Disabling CPU Boost in Silent and Performance modes reduces power draw and heat without meaningfully affecting GPU-limited game performance. Most handheld games — open-world RPGs, racing games, action titles — are GPU-bound, not CPU-bound, so the CPU is sitting partly idle while the GPU is the bottleneck. Leaving CPU Boost on in those scenarios burns watts without delivering frames. Keep it enabled only in Turbo+ mode when plugged in, where the power budget can absorb the overhead. Disable via: Settings → Performance → Eco Assist → CPU Boost [5].

Frequently Asked Questions
What’s the best TDP setting for the ROG Ally X?
Performance mode at 17W is the best general setting for gaming on battery. It handles the majority of modern games — including demanding AAA titles with FSR enabled — while delivering 3 to 3.5 hours from the 80Wh cell. Step up to Turbo at 25W when you need more performance headroom, and use Turbo+ at 30W only when plugged in and targeting maximum FPS.
Should I set VRAM to 6GB or 8GB on the ROG Ally X?
8GB is the better allocation for the ROG Ally X specifically, because its 24GB LPDDR5 can spare the reservation without starving Windows or background processes. This differs from the original ROG Ally (16GB), where 6GB was the safer limit. The one exception: CPU-heavy simulation titles benefit from staying at 6GB to preserve system RAM for the processor [2, 3].
Does the 40 FPS cap make games look bad on the Ally X?
Less than most players expect. The 40 FPS cap was designed specifically for the 120Hz panel — 40 FPS divides evenly into 120Hz, so each frame holds for exactly three refresh cycles, delivering even pacing without judder. For story-driven RPGs, open-world games, and slower-paced titles where smooth 60+ FPS isn’t critical, 40 FPS on battery is consistent and fully comfortable to play.
Does the ROG Ally X have an OLED display?
No. The 2024 ROG Ally X uses a 7-inch 1080p IPS-level panel with 500 nits peak brightness and Gorilla Glass Victus protection [7]. If OLED is a priority, see our best handheld gaming PCs 2026 guide for devices with OLED screens.
