As seen in our recent reviews of AMD's new Radeon RX 9070 and Radeon 9070 XT GPUs, one of the significant improvements with RDNA 4 is the arrival of FSR 4. The latest version of AMD's FidelityFX Super Resolution is exclusive to its latest generation of desktop graphics cards because it introduces a new complex AI model for upscaling, dramatically improving image fidelity compared to FSR 3.1.

Like with NVIDIA DLSS, if FSR 4 is available in a game using the 'Quality' preset at 1440p or 4K can be considered 'free performance' as it offers a clean and detailed image comparable to native rendering with TAA. However, as FSR 4 support is only available in a fraction of games compared to DLSS 3 and DLSS 4, it's not yet a selling point or reason to choose Radeon over the competition.
The good news is that AMD has noticed the positive response to FSR 4 among reviewers and RDNA 4 early adopters and is actively working with developers "to make sure the next blockbusters that come out are enabled with FSR 4 technology."
"Developer adoption is very strong," David McAfee, Corporate VP and General Manager at AMD, recently said. "There is a ton of interest, I think that when you look across our game ecosystem, the partnerships that we have, carrying over from the console world into the Radeon world gives us very broad reach in terms of our ability to interact with game developers and provide a set of capabilities to those studios. We're around the world with game developers, regardless of where they're located, we are working very hard to make sure the next blockbusters that come out are enabled with FSR 4 technology because we think it's just such a significant improvement to the gameplay experience that we want it to be everywhere."

FSR 4 is, in many ways, a reboot for AMD's approach to Super Resolution. It moves away from a more open approach that works on all hardware to one that is purely focused on image quality and leverages its own bespoke AI hardware found in its latest RDNA 4 GPUs.
Leveraging its console partnerships (Sony is looking to 'backport' FSR 4 and bring it to the PlayStation 5 Pro in 2026) will help get FSR 4 into more games. Microsoft is touting next-gen AI and machine learning for its next Xbox console, and the PS6 is expected to introduce even more powerful AI hardware than what's found inside the PS5 Pro. The good news is that even though GeForce RTX dominates the PC gaming space, RDNA 4 is selling out everywhere, which means more cards are available, providing more reasons for developers to add FSR 4 support in more titles.
For those who are not willing to wait, there's a tool called Optiscaler that allows FSR 4 to be modded into many more games.
