AMD’s decision to limit FSR 4 to RDNA 4 graphics cards continues to frustrate a huge portion of Radeon owners, and the company still isn’t explaining why. More than a year after FSR 4 arrived alongside RDNA 4-based Radeon RX 9000 GPUs, questions about official support for RDNA 2 and RDNA 3 (RX 6000 and RX 7000 series) remain unanswered—even though many users believe the technology can work on older cards.
The situation stands out even more because competing upscaling technologies have typically remained available across multiple generations of hardware. In AMD’s case, however, FSR 4 has effectively stayed locked to the RX 9000 family, leaving RX 6000 and RX 7000 owners waiting for clarity on whether an INT8 version of FSR 4 will ever be officially enabled for their GPUs.
What makes the silence harder to understand is that the community has long pointed out that DLL files already exist, and many insist this strongly suggests compatibility with RDNA 2 and RDNA 3. AMD has been asked repeatedly about bringing INT8 FSR 4 to these cards, but the company has never provided a clear “yes” or “no,” and hasn’t publicly explained the restriction.
Adding fuel to the speculation, former FSR head of development Colin Riley was recently asked directly about AMD’s lack of communication. Instead of giving a straightforward response, he replied with a meme-style GIF that reads: “I prefer not to speak. If I speak, I am in BIG trouble.” The reaction implies he may know the reason behind AMD’s decision, but can’t share it publicly—leaving Radeon users to guess whether the holdup is technical, strategic, or something else entirely.
While AMD remains quiet, enthusiasts haven’t waited around. Workarounds to enable FSR 4 on RX 6000 and RX 7000 GPUs have been circulating, and many users report strong results. Third-party tools such as Optiscaler have also been used to get FSR 4 running successfully, with claims that FSR 4 Balanced mode can outperform FSR 3.1 Quality mode in certain scenarios. Users describe sharper image quality, improved clarity, and reduced ghosting and shimmering compared to FSR 3.1. Although FSR 4 can be more demanding, performance can reportedly be improved with the right tweaks and settings.
It doesn’t stop at FSR 4. Some reports claim FSR 4.1 can also be made to work on RDNA 3 through similar methods, with results resembling what users see on RDNA 4. Even so, AMD has continued to keep official FSR 4.1 support exclusive to the Radeon RX 9000 series.
For now, millions of RDNA 2 and RDNA 3 owners are stuck in limbo: unofficial methods suggest FSR 4 can run on their hardware, but AMD won’t confirm whether official support is coming—or why it’s being held back in the first place.
