ASUS scheduled the AMD FSR Upscaling 4.1 preview driver for the ROG Xbox Ally X and ROG Xbox Ally X20 on October 23, 2026. GameTechPlanet demonstrated the driver as available on that date. The update lets compatible games use FSR 4.1, an upscaler that uses machine learning to reconstruct higher-resolution images from lower-resolution game frames.
What FSR 4.1 does in compatible games
ASUS says the driver can replace the upscaler in games that support FSR 3.1 or newer, and cites more than 400 compatible games. The game still needs its own FSR option enabled. A game’s graphics menu may continue to say “FSR 3.1”: that label comes from the game, while the driver can apply FSR 4.1 when the game launches.
ASUS recommends against using FSR and Radeon Super Resolution (RSR) together. RSR is a system-level upscaler intended for games without FSR support. For PC-side context, NeoTeo previously covered the separate FSR 4.1 support for Radeon RX 6000 graphics cards.
How to install and enable the preview
On a ROG Xbox Ally X or ROG Xbox Ally X20, open Armoury Crate SE and go to Update Center > Preview Updates to install the GPU driver. Preview software may contain bugs or instability, ASUS cautions.
After installation, add the AMD FSR Upscaling tile to Command Center and switch it on. Then launch a compatible game and enable FSR in its graphics settings. The driver-side replacement takes effect when the game starts, so close and relaunch the game after changing the tile.
Early results vary by game
GameTechPlanet reported clearer image details in selected comparisons and noted a performance tradeoff. AllyWired described improved visual clarity with similar raw performance in its selected comparisons. Community reports also differ: one user reported recurring stutter in Forza Horizon 6 with the preview driver, while other users described higher frame rates or better image quality in different games and settings. These are individual observations, not a reliable frame-rate prediction for every title.
The two creators’ comparisons show why the result depends on the game and settings: FSR 4.1 is an upscaler, not a guaranteed frame-rate increase.
