How to Turn On AMD FSR 4.1 Upscaling on the ROG Xbox Ally X and X20
ASUS is rolling out a preview AMD FSR 4.1 driver for the ROG Xbox Ally X and X20 on October 23. Here's how to install it and turn upscaling on.
AMD's upscaling technology is finally reaching ASUS's newest handhelds. Starting October 23, the ROG Xbox Ally X and ROG Xbox Ally X20 can install a preview GPU driver that turns on AMD FSR 4.1 Upscaling, the AI-driven image reconstruction tech AMD has spent the past year rolling out across desktop and laptop Radeon cards. ASUS confirmed the rollout in its own ROG Ally articles hub, and it is opt-in rather than automatic, so owners of either handheld need to dig into settings to find it.
What AMD FSR 4.1 Changes on a Handheld
FSR 4.1 is AMD's latest version of its FidelityFX Super Resolution upscaler, which renders a game at a lower internal resolution and reconstructs it to the display's native resolution using a machine-learning model, aiming for sharper detail than older spatial upscalers at the same performance cost. For handhelds specifically, ASUS says AMD built a new model that is less than half the size of the original INT8 version used on desktop Radeon GPUs, tuned around the Ryzen AI Z2 Extreme chip that powers both the Ally X and Ally X20. That matters because handhelds have far less thermal and power headroom than a desktop graphics card, so a lighter model leaves more of the chip's budget for the game itself.
The toggle works retroactively, too. According to ASUS, flipping FSR Upscaling on in Command Center also activates it in any older game that already supports FSR 3.1 or newer, a list the company puts at more than 400 titles, without needing a separate per-game patch. That is a meaningfully different approach from how NVIDIA ships DLSS, which generally needs each developer to add support title by title; AMD's upscaler has always run on ordinary shader hardware rather than dedicated AI silicon, which is also why older RDNA 2 desktop cards and now a Z2 Extreme-class handheld chip can run the newest version at all.
Which Ally Models Get It, and When
The rollout is split by hardware. Only the ROG Xbox Ally X and ROG Xbox Ally X20, both built around the Ryzen AI Z2 Extreme, are getting the October 23 preview driver. The original, cheaper ROG Xbox Ally (built on the standard Ryzen AI Z2) is not part of this preview; ASUS says that model will get its own GPU driver update "coming soon," without a firm date. If you own the base Ally, checking Armoury Crate SE periodically for an official update, rather than the preview channel, is the move for now.
The handheld rollout also lines up with a wider AMD push. The FidelityFX Super Resolution family reached Radeon RX 6000-series desktop GPUs through the same wave of updates, months ahead of AMD's own original 2027 target for that hardware. It is also one more entry in a crowded field: Valve's Steam Deck, the closest rival to ASUS's ROG Ally lineup, runs on AMD silicon too but ships its own Linux-based SteamOS rather than Armoury Crate, so this particular driver and its preview channel are specific to ASUS's Windows-based Ally line.
Installing the Preview Driver Through Armoury Crate SE
Because this is a preview build, ASUS routes it through a separate update channel rather than the normal driver queue. On an Ally X or Ally X20:
- Open Armoury Crate SE from the handheld's home screen.
- Go to Update Center, then switch to the Preview Updates tab.
- Find the latest GPU driver listed there and download it.
- Let the device install and restart as prompted.
Once this preview graduates to a stable release, ASUS says the same driver will reappear automatically under the regular Official Updates tab, so owners who skip the preview now will still get FSR 4.1 eventually without hunting for it.
Turning FSR 4.1 On in Command Center and In Your Games
Installing the driver alone does not switch anything on. ASUS lays out a second, separate step to actually enable the feature:
- After installing the preview GPU update, open the Command Center overlay (the button that brings up quick settings).
- Press Y to edit the layout, then add the new FSR tile if it is not already pinned.
- Make sure that tile is switched on.
- Launch a supported game and enable FSR in its own in-game graphics menu, the same way you would turn on any upscaler.
That Command Center toggle is also what retroactively applies FSR Upscaling 4.1 to older titles running FSR 3.1 or above, so it is worth checking even in games you installed long before this update existed.
What to Watch Out for in a Preview Build
ASUS is upfront that this is not a finished release. The company's own article warns that preview updates "may still contain bugs or instability," and it suggests sticking with the stable driver if you need a reliable device rather than one to experiment on. A couple of practical notes worth keeping in mind:
- Don't run FSR Upscaling alongside RSR (Radeon Super Resolution) at the same time. RSR is a system-level upscaler meant for games that don't support FSR directly, and ASUS advises against stacking the two.
- Neither AMD nor ASUS has published performance numbers for the handheld model yet, so treat any frame-rate claims you see online as unverified until ASUS ships a stable build.
- ASUS is actively asking preview users to report bugs, which is also the fastest way to help push a stable release out sooner.

Xbox Series X|S and What Comes Next
The Ally rollout is one piece of a bigger AMD and Xbox push. In the announcement video AMD posted alongside the Ally news, Xbox CTO Scott Van Vliet confirmed the same FSR 4.1 model is also headed to Xbox Series X and Series S consoles, though without a release date yet. AMD has tied that future console work to Project Helix, its umbrella effort for next-generation upscaling and frame generation technology that is expected to eventually include a successor called FSR Diamond.
None of that changes what Ally owners can do right now. For anyone with an Ally X or Ally X20, the preview is a free way to try sharper upscaling in hundreds of already-installed games today, at the cost of tolerating the occasional preview-build hiccup while ASUS and AMD work through bug reports toward a stable release that, per ASUS, will eventually reach the same devices automatically through the regular Official Updates tab.
