fsr redstone

FSR Redstone is AMD's machine-learning-driven upscaling and frame generation suite, introduced with the Adrenalin 25.12.1 driver in December 2025. It bundles upscaling, frame generation, ray-tracing denoising, and a future radiance-caching system. However, the full feature set is explicitly built for RDNA 4 (Radeon RX 9000) hardware, leaving RDNA 3 and older GPUs without full support. Early benchmarks show measurable framerate uplifts on RDNA 4 when Redstone features are enabled. Discussions on WindowsForum explore whether RDNA 3 GPUs could ever receive limited support, but the consensus is that full implementation is unlikely without AMD approval due to hardware design and risk management constraints.
