AMD has started extending FSR 4.1, its newest upscaling technology, to graphics cards it had not originally built the feature for. The company released the AMD Software: Adrenalin Edition 26.6.2 driver on June 22, 2026, bringing official FSR Upscaling 4.1 support to Radeon RX 7000 series cards, GPUs based on the older RDNA 3 architecture, across more than 300 games. The release lands about a month earlier than AMD’s own July target, announced back in May by Jack Huynh, AMD’s Senior Vice President and General Manager of the Computing and Graphics Group.
Huynh confirmed the rollout directly on X: “Today, we’re bringing AMD FSR Upscaling 4.1 to Radeon RX 7000 Series graphics cards, extending our latest machine learning powered gaming experience to millions more players across more than 300 games.” He added that AMD is separately developing lightweight machine learning models aimed at RDNA 3-based APUs, AMD’s integrated graphics chips, without giving a release date for that work.
FSR 4.1 first shipped exclusively for Radeon RX 9000 series cards built on the newer RDNA 4 architecture. Those chips read the upscaling model using FP8, an 8-bit floating point format the silicon supports natively. RDNA 3 hardware has no equivalent FP8 path, so engineers had to convert the entire model to run on INT8, an 8-bit integer format instead. AMD describes this as a full rebuild rather than a simple recompile, and the company states the converted model holds the same visual fidelity as the version running on RDNA 4. The explorer below breaks down exactly where each AMD GPU generation currently stands.

Which AMD GPU Gets FSR 4.1, and When?
AMD is rolling its FSR 4.1 upscaler backward across four GPU generations, but not on the same date or through the same path. Tap each lane to see how far the rollout has actually reached.
RDNA 4 chips read the FSR 4.1 model in FP8 format by design. RDNA 3 chips can only process INT8 math, so AMD had to convert the entire model to a different number format rather than simply recompiling it, the reason RX 7000 support arrived roughly a year after RX 9000’s.
Driver and rollout details are confirmed by AMD’s official Software: Adrenalin Edition page.
The driver update covers upscaling only. RX 7000 cards do not gain FSR 4.1’s frame generation component in this release; they continue to use FSR 3.1 Frame Gen alongside the new upscaler. AMD has also confirmed that RDNA 2-based Radeon RX 6000 cards are scheduled to receive their own FSR 4.1 build in early 2027, the next phase of the same backward-compatibility plan that just reached RDNA 3.
Community testing reached some of this hardware before AMD’s official driver did. A leaked FSR 4.1.1 INT8 build briefly surfaced through Valve’s Proton Experimental depot for SteamOS before Valve pulled it back; a Reddit user managed to download the file first. Run through the third-party OptiScaler tool, that leaked build reportedly worked on an RX 7800 XT (RDNA 3), an RX 6900 XT (RDNA 2, with visible artifacts), and a Radeon 890M integrated GPU built on RDNA 3.5, an architecture whose FSR 4.1 future AMD itself has described inconsistently. The sequence of events is laid out below.
Timeline
From Leak to Official Driver
FSR 4.1’s path to RDNA 3 ran through community leaks before AMD shipped anything official. Here is the order it actually happened in.
Valve’s hardware sits squarely inside this rollout. The company’s upcoming Steam Machine runs a custom RDNA 3 GPU, putting it in line for the same official FSR 4.1 upscaling support RX 7000 desktop cards just received. SteamOS developer Pierre-Loup Griffais addressed the timing directly to Digital Foundry: “We don’t have a time-frame to share with you, but we’re excited that it’s coming through on the same schedule… Any game that supports the FSR SDK with a new enough version that it has the upgrade path within the AMD software will just light up.” Griffais added that the FSR option in supported games will automatically switch over to FSR 4 once Proton rolls out support for it, meaning Steam Machine owners will not need to take any manual steps once Valve enables the upgrade path.
AMD’s FSR rollout sits inside a broader stretch of hardware news this month where companies have had to clarify product timelines, pricing, or specifications after early reports surfaced ahead of an official statement. Apple’s Tim Cook recently described rising memory chip costs as “unavoidable” for future device pricing, Samsung’s Galaxy Watch 9 Classic has missed expected regulatory filing deadlines ahead of its launch, and Snap’s AR glasses division has pointed to similar component cost pressure behind its $2,195 Specs pricing. Software-side timing slips have shown up too: Disney Plus users reported a login outage this month that the company had to address after the fact, and the technology talent market saw its own unscheduled shift when Noam Shazeer left Google for OpenAI months after rejoining.
This piece covered AMD’s June 22, 2026 release of official FSR Upscaling 4.1 support for Radeon RX 7000 (RDNA 3) graphics cards through the Adrenalin 26.6.2 driver, the technical conversion from FP8 to INT8 that made the RDNA 3 version possible, AMD’s confirmed 2027 timeline for RDNA 2 support, the leaked INT8 build that surfaced through Valve’s Proton Experimental channel, and Valve’s confirmation that Steam Machine will receive the same upscaling support on a comparable schedule. AMD’s plans for RDNA 3.5 integrated graphics remain unresolved: one AMD executive described the feature as not planned for that architecture, and another AMD executive later said internally no such decision has been made.
