The ROG Xbox Ally handheld has just received its most important update since launch, and it genuinely feels like a new phase for this compact gaming PC. The latest firmware and software package focuses on three big pillars that matter most to handheld players: higher and more stable game performance, smarter power consumption, and quality-of-life tweaks that make the device quicker and more pleasant to use day to day.
One of the standout additions is the deeper control over the CPU on the X model, with new options for managing performance cores and efficiency cores. 
This lets users decide how aggressively the processor should boost, or when it should lean toward efficiency instead. In practice, it means you can fine-tune the Ally X for a demanding AAA title with all the P-Cores ready to go, or dial things back when you are running indie games and want to stretch battery life on a long commute.
The update also refines how you interact with games on the go. A new quick access path to full-screen mode cuts down on the fiddling required to get your titles front and center, which is particularly handy when you regularly jump between the Windows desktop and your library. Equally important is the change to the built-in FPS limiter: the old 45 FPS cap has been adjusted to 40 FPS, a number that syncs more cleanly with the Ally panel’s 120 Hz refresh rate. This might sound minor on paper, but it delivers noticeably smoother frame pacing and less visual judder, which handheld screens tend to amplify.
Battery life has always been one of the biggest pain points for powerful handheld PCs, and the ROG Xbox Ally is no exception. That is why the improvements to power consumption in Modern Standby are such a welcome change. The device now drains less energy while sleeping, so you are less likely to pick it up after a day or two and find the battery unexpectedly low. It does not magically turn the Ally into a battery champion, but it makes real-world endurance more predictable and reduces the anxiety of watching the percentage tick down every time you close the lid.
Under the hood, the AMD GPU driver has been updated to version V25.10.27, bringing a fresh round of optimizations for modern games. Users can expect smoother performance, improved compatibility with recent releases, and fewer random stutters when switching between different power profiles. On top of the graphics boost, the update also tightens up firmware stability and overall system responsiveness, so menus feel snappier, background tasks behave more reliably, and crashes or glitches should be less frequent. For a device that doubles as both a console-like handheld and a tiny Windows PC, that extra layer of polish makes a real difference.
The features highlighted here are only part of what is described in the official update notes, which go into even more technical detail for enthusiasts who like to dive deep into changelogs. Taken together, though, this is easily the biggest step forward for the ROG Xbox Ally lineup since launch, particularly for the X model. The experience still is not as hassle free as a traditional living-room console, and some Windows quirks inevitably remain, but this patch makes the Ally a much more tempting entry point into PC handheld gaming. If you want a broader perspective on how the hardware itself holds up, looking at in-depth impressions such as the review by David Carcasole of the X counterpart helps put these improvements into context and shows just how far the system has come in a short time.

Nice update but Windows on a handheld still feels kinda janky tbh
Updated mine and games do feel less stuttery, especially on lower TDP, surprised it helps this much
