AMD ships FSR 4.1
AMD rolled out Adrenalin 26.3.1 with FSR 4.1 and Ray Regeneration 1.1 for RX 9000 cards — new upscaling and ray‑tracing tools aimed at RDNA4 hardware. Caveat: users are still seeing crashes in titles like Death Stranding 2 on older RX 5000 hardware and some FSR indicator bugs persist, so patch cautiously if you rely on stability (thefpsreview.com).
Adrenalin Edition 26.3.1 was published as a WHQL driver on March 19, 2026, and the release notes list day‑one support for Crimson Desert and DEATH STRANDING 2: ON THE BEACH. (techpowerup.com)) AMD pushed an updated FSR “Redstone” SDK 2.2 for developers the same week, explicitly adding support for FSR Upscaling 4.1 and Ray Regeneration 1.1 so studios can integrate the features directly. (tweaktown.com)) FSR Upscaling 4.1 in this release is restricted to Radeon RX 9000 (RDNA 4) graphics cards; RX 6000 and RX 7000 series are not listed as supported for FSR 4.x in the 26.3.1 package. (noobfeed.com)) AMD and Sony say FSR 4.1 shares the same neural‑network foundation used in the PlayStation 5 Pro’s updated PSSR, a result the companies attribute to collaboration under “Project Amethyst” and public exchanges between AMD’s Jack Huynh and PS architect Mark Cerny. (techspot.com)) The 26.3.1 changelog documents several fixes shipped with the driver — including a resolved Cyberpunk 2077 crash when loading a saved game with Path Tracing enabled, restored ability to enable AMD Noise Suppression on RX 6000+ cards, and fixes for intermittent loss of mouse/keyboard input. (techpowerup.com)) AMD’s release notes also list outstanding issues beyond the headline features: FSR Upscaling and Frame Generation may appear inactive in Battlefield 6 on some RX 9000 systems, texture flickering can occur with AMD Record and Stream, RoadCraft may see intermittent crashes on RX 9000, and rare driver timeouts have been reported on systems using the AMD Ryzen AI 9 HX 370.
