Redditor Enables FSR4 Redstone On RDNA3
6.0
AMD released FSR4 Redstone but limited the feature to RDNA4 RX 9000-series GPUs; Reddit user u/AthleteDependent926 enabled it on RDNA3 via Linux and Valve’s Proton. The workaround brings neural radiance caching, ray regeneration and AI upscaling to Radeon RX 7000-series cards with higher performance cost—reportedly 0.13ms latency on an RX 7800 XT versus 0.07ms for older frame generation—and follows an August 2025 source-code leak.
Key Points
- 1Enables FSR4 Redstone on RDNA3 GPUs using Linux plus Valve’s Proton compatibility layer.
- 2Highlights AMD’s RDNA4-only restriction and sparked community reverse-engineering and modding efforts.
- 3Means older Radeon RX 7000 GPUs can run ML frame-generation features at higher performance cost.
Scoring Rationale
Community-enabled workaround provides usable access to new ML frame generation, limited by hardware scope and unofficial credibility.
