If you own an Xbox Series X and you’ve been eyeing a $900 PS5 Pro for GTA 6, hold that thought. Microsoft and AMD have just handed Xbox developers the tool that could make your six-year-old console look and run noticeably better, without you buying anything.
The tool is FSR 4.1, AMD’s newest AI upscaler. As UNILAD Tech put it, it could effectively turn the Series X into a “Pro” model. That’s a fun headline, and there’s real substance behind it. But there’s also a catch that most of the excitement skips over: it doesn’t switch on by itself.
The short version
- On November 5, Microsoft released FSR 4.1.2 to Xbox Series X|S developers through its GDK, with “Full” and “Lite” models tuned for each console.
- FSR 4.1 renders games at a lower resolution and uses machine learning to rebuild a sharper image, freeing up power for higher frame rates.
- It is not a system update. Each game needs a patch from its developer.
- Series X is well placed to run it: it has more GPU compute units than the base PS5 and supports the INT8 math the AI model uses.
- There’s no word yet on whether GTA 6, out November 19, will use it.
What actually happened
AMD and Microsoft first announced FSR 4.1 for the whole current Xbox lineup on October 21: Series X, Series S, and both the ROG Xbox Ally and Ally X handhelds. On October 23, beta drivers started reaching the Ally handhelds. Then on November 5, Microsoft’s developer team posted that “AMD FSR Upscaling 4.1.2 on XBOX Series X|S is available to developers today,” with a new sample in the Game Development Kit showing off two versions of the model.
That last step is the important one. Until developers had it, FSR 4.1 on Series X was a promise. Now studios can start building it into their games.
How upscaling squeezes out more performance
The trick behind FSR, and rivals like Nvidia’s DLSS and Sony’s PSSR, is simple to describe. Instead of drawing every pixel of a 4K image, the console draws a smaller image and an algorithm fills in the rest. FSR 4 and 4.1 use a trained machine learning model for that fill-in step, which is why they look so much cleaner than the older FSR 2 and 3 that consoles have relied on for years.
The savings are huge because pixel counts grow fast. A 4K frame has about 8.3 million pixels. A 1440p frame has 3.7 million, less than half. A 1080p frame has about 2.1 million, a quarter of 4K.
The catch is that the AI model itself needs GPU time to run. That’s where the Series X has an edge. According to analysis from TheSixthAxis, the Series X supports INT8 operations from AMD’s RDNA 2 feature set, which the AI model can use, while Sony left INT8 out of the base PS5. Sony’s own version of this tech for the base PS5, called QSSR, has to use slower FP16 math as a result. The Series X also simply has more compute units for the job.
| Console | GPU compute units | GPU power | AI upscaler |
|---|---|---|---|
| Xbox Series S | 20 | 4 TFLOPS | FSR 4.1 (Lite model likely) |
| Xbox Series X | 52 | 12.15 TFLOPS | FSR 4.1, per game |
| PS5 | 36 | 10.28 TFLOPS | QSSR, per game |
| PS5 Pro | 60 | 16.7 TFLOPS | PSSR (dedicated AI hardware) |
We covered Sony’s side of this race when it brought AI upscaling to the base PS5 with Marvel’s Wolverine. FSR 4.1 is Microsoft’s answer, and on paper the Series X is the better machine to run it.
What the early results look like
There are no Series X games with FSR 4.1 yet, so the best evidence comes from the Xbox Ally X handheld, which got the tech first. In Windows Central’s testing there, Cyberpunk 2077, Control Resonance and Gears of War: E-Day held more consistent frame rates with FSR 4.1 on. The Witcher 3 remaster ran closer to 60 fps and looked sharper. Games that looked soft or blurry in their Quality modes, including Warhammer 40,000: Darktide, cleaned up noticeably.
It’s not perfect everywhere. Games built around ray-traced lighting, like Silent Hill 2, still need more work. And a handheld running at 1080p isn’t a console running at 4K, so results won’t carry over one to one. Digital Foundry’s look at Sony’s equivalent on the base PS5 gives a useful hint, though: in Marvel’s Wolverine, the AI upscaler cost about 8 to 10 fps and 1.5 to 1.8 ms per frame, but the game still ran well above 60 fps with a cleaner image. Developers can make up for that cost by rendering from a slightly lower resolution.
So, is it really a “Pro” upgrade?
Kind of. A Pro console gives every game more raw power. FSR 4.1 gives developers a much better tool, and it’s up to them to use it. That’s an important difference.
- New games are the most likely to adopt it, especially big releases with Xbox versions still in development.
- Recent hits may get patches if publishers think it’s worth it.
- Older games probably won’t. Windows Central notes it won’t be added to existing console games automatically.
The pricing context explains why people care. Sony’s PS5 Pro carries a hiked list price of around $900, and used PS5 Pro units at GameStop have sold for $1,399 as GTA 6 demand spiked. Microsoft’s next console, Project Helix, has been rumored to cost as much as $1,200. A free software upgrade for a console people already own is a very easy sell.
What about GTA 6?
This is the question everyone’s asking, and the honest answer is that nobody knows. Rockstar has marketed GTA 6 as looking best on PS5 Pro and hasn’t said anything about FSR 4.1 on Xbox. With launch on November 19, just two weeks after developers got access, a day-one implementation would be surprising. A post-launch patch is possible, but it’s speculation for now.
Either way, if you’re playing on a Series X, you’ve got a few things you can control before launch night. Our guide to PS5 and Xbox settings to change before GTA 6 covers performance modes, HDR and storage.
