Following AMD's launch of FSR Redstone exclusive to RDNA 4 GPUs, a Reddit user has devised a Proton-based workaround allowing the frame generation tech to run on older RDNA 3 cards through Linux, fueling debates on hardware restrictions.
Ten days after AMD's FSR Redstone debut—limited to RDNA 4 GPUs like the RX 9000 series—Reddit user u/AthleteDependent926 shared a workaround on December 20, 2025, bringing the technology to RDNA 3 hardware (e.g., RX 7000 series) on Linux.
The solution leverages Proton, Valve's compatibility layer for Windows games on Linux, to bypass driver restrictions. While unofficial, it demonstrates the tech's underlying compatibility with prior-gen GPUs, though performance and stability may vary.
Tom's Hardware and Startup News covered the mod, noting gamer frustration with AMD's exclusivity. This community effort highlights tensions between proprietary features and open access in PC gaming, potentially inspiring broader adoption without hardware upgrades.
