AMD has announced a new update to support FSR4 across the Radeon RX 7000 and Radeon RX 6000 series graphics cards, giving handheld gaming systems and older graphics cards a new lease of life. The update will improve the quality and performance of images and graphics across many devices, including RDNA 3 APUs such as the Z1 Extreme and Z2 Extreme chips. It also provides greater long-term value for current gaming equipment, without the need to upgrade individual parts.

AMD finally made the decision that many users had been waiting for. If you're not a hardcore gamer who knows all the details about handhelds, it was one of the biggest things in the handheld community for many years, especially at the budget side, where you want to get the most out of your games.

FSR4 Released for RDNA 3 and Older Radeon Hardware

AMD is bringing FSR4 support to the RX 7000 and RX 6000 series graphics cards, which should also include RDNA3 APUs like the Z1 Extreme and Z2 Extreme. While AMD has not officially confirmed handheld APUs, there were indications they were present, particularly the appearance of a handheld device at the presentation.

It's still unclear whether Steam Deck support is coming, but in the meantime, devices running the Z1 Extreme and Z2 Extreme should get a huge performance boost. The most obvious one is here. Existing systems will now provide improved performance and image clarity without any additional expense. With FSR4, upscaling in performance mode is once again a viable solution.

In previous versions of FSR, performance mode would sometimes appear "muddy" and without image clarity. FSR4 aims to solve this problem by making the aggressive upscaling mode's settings more usable while keeping the pictures clean.

As of now, preliminary testing results are varied. There are early benchmarks out there, but they seem modest in scope for the feature, which users can already sideload. For some tests, this FSR4 performance mode can behave similarly to FSR 3 quality mode. That's what the target users don't want to see. The aim is to achieve better image quality and better overall performance. Hopefully, AMD driver tweaks will continue to make it better once released.

PSSR2 Becomes the Benchmark for FSR4

FSR4 is measured by PSSR2. Z1 Extreme and Z2 Extreme chips could get one of the biggest software-based improvements in handheld gaming if AMD can ramp up image quality to near PSSR2 levels. The future is important, and that's a thought you need to consider. Even without advanced ray tracing acceleration, better upscaling can help existing gear last for years.

Advanced GPUs such as the Radeon RX 7900 XTX will also be getting a boost. In many instances, those cards are already more powerful than the PS5, and with enhanced upscaling, they may stay competitive for a while. The larger question is what will happen to ray tracing performance and image reconstruction with the release of FSR 4, which will become common across most platforms.

Handheld Gaming Could Be the Most Beneficial Sector

It's not just about desktop GPUs. This update may prove to be a game-changer for handheld gamers. One of the most interesting examples is the Xbox Ally powered by the Z2 Go chip. Handhelds with lower frame rates typically have lower native resolutions, such as 720p, in order to keep the frame rate playable. FSR4 could help these systems achieve better performance in higher resolutions and also enhance image clarity.

That's where the value is clear. These handhelds are smaller and cheaper, and might now offer more visually appealing gameplay without the need for more powerful equipment. Z1 Extreme and 32GB options are also ones that they're interested in seeing on newer hardware, such as the Legion Go2 and Legion Go S.

The entire gaming sector could even benefit, too. What could benefit the upcoming Steam Machine setup with a trimmed-down RX 7600 non-XT GPU is a significant performance boost from FSR4. On its own, this GPU aims for 4K gaming at lower settings.

Having better upscaling support could make it much more realistic at high settings.

These are the features that users desire in today's gaming devices. The software could be optimized to improve performance without requiring costly hardware upgrades. Radeon RX 7900 XTX will see immediate benefits, but the major impacts may be felt by existing Radeon users. GPUs now may get a much-needed boost in longevity.

As the cost of gaming hardware continues to rise, many people using older or budget models will find this useful. While FSR 4 was first released with a few limitations and received criticism for them, it will make a huge difference when it is added to older hardware that lacks the password. Testing on a wide range of handhelds and desktop GPUs over the next few months will give a clearer idea of the performance and image-quality boosts that will come with final optimizations.
