Microsoft brings upscaling to Xbox handheld
Microsoft's Automatic Super Resolution has been released for the ROG Xbox Ally X, bringing the company's answer to Nvidia's DLSS to the handheld. It works in handheld mode, which is where the device spends most of its time away from a TV.
The feature renders games at a lower internal resolution and then upscales the image to the screen's native resolution. The aim is to keep pictures looking sharp while asking less of the processor and graphics hardware, a consideration that carries particular weight on a battery-powered machine.
The ROG Xbox Ally X is the more powerful of the two Xbox-branded handhelds built with Asus. It runs Windows rather than a locked-down console system, so it sits somewhere between a games console and a small gaming PC. That mix makes a Microsoft-made upscaler a notable addition. Handheld PC owners have long relied on a patchwork of vendor tools to get playable frame rates from demanding titles.
The trade-offs of upscaling
Modern games are expensive to draw at full resolution. A handheld with a small screen and a limited power budget has to make trade-offs between sharpness, smoothness and battery life. Upscaling shifts that balance.
Instead of drawing every pixel natively, the game draws fewer and the upscaler fills in the rest. Done well, the result looks close to native resolution while running faster. Done badly, it can bring softness, shimmering on fine detail or odd artefacts around moving objects. Results vary from game to game, and the quality of the upscaling is the point on which rival systems are judged.
DLSS, from Nvidia, is the best-known example, and AMD and Intel have their own equivalents. Microsoft's version is designed to be built into the system rather than tied to a graphics card brand, which fits a platform that spans several kinds of hardware.
Impact on UK owners
The most direct effect is on owners of the ROG Xbox Ally X, who gain another way to tune performance without leaving the device's own settings. Anyone considering a purchase may also weigh the feature against rival handhelds, many of which already offer their own upscaling options.
For UK households, the practical gains are tied to how handhelds tend to be used. People play on trains, in bed, in the garden and on holiday, often away from a plug. A feature that lowers the load on the chip can stretch a charge or hold a steadier frame rate in a demanding game. It also helps newer releases remain playable as titles grow more demanding over the life of the hardware.
Owners of handhelds that run warm will have an interest too. Lower workloads generally mean less heat and less fan noise, though the difference depends on the game and the settings chosen.
Updates and settings
Features of this kind arrive through system and graphics software updates, so a handheld needs to be fully updated before the option appears. Checking for updates in Windows and in the Xbox app is the first step.
Games that already run at a comfortable frame rate gain least from upscaling. The clearest benefit comes in titles where the frame rate dips in busy scenes or where the battery drains quickly.
Where a game offers its own resolution scale or a built-in upscaler, switching several options on at once makes it hard to judge what is helping. Text, thin lines such as fences and wires, and fast-moving objects are where upscaling flaws tend to show first. A game that looks soft or shimmery with the feature on may be better served by a higher internal resolution, or by switching the feature off for that title.
Many handhelds also let owners choose a power mode that caps how much energy the chip draws. A lower power mode paired with upscaling is one route to longer battery life, while a higher mode paired with it can push frame rates up in heavier games.
Docked play
The headline benefit is in handheld mode, where the screen is small enough that upscaling artefacts are harder to spot. On a large television the same shortcuts can be easier to see, because the image is magnified. Owners who connect the device to a TV may find they prefer native resolution in lighter games and keep the upscaler for the demanding ones.
Next steps for Microsoft
Microsoft has framed the release as part of its wider push to make Xbox games run well across a range of hardware, and handhelds are an obvious test of that ambition. The company's upscaler now competes directly with tools that players already know. How it compares in practice will become clearer as owners try it across a library of games and share their findings.
Game support is the next thing to watch. Upscalers tend to perform best when developers tune their games for them, and the number of titles that work smoothly with Microsoft's version will shape how much it matters day to day. Reviewers and players are likely to put it through its paces against DLSS and the alternatives over the coming weeks.
The release gives ROG Xbox Ally X owners another option in the settings menu, and a reason to revisit the games that ran a little too hot or too slowly the first time round.
