Overview
- AMD’s Adrenalin 26.3.1 driver enables FSR Upscaling 4.1 on Radeon RX 9000 GPUs, adds day‑one support for Crimson Desert and Death Stranding 2, and upgrades Ray Regeneration to version 1.1.
- FSR 4.1 targets sharper detail, smoother camera motion, and faster Ultra Performance mode in ML‑powered titles according to AMD.
- Optiscaler v4.0.2b deploys a leaked FSR4 INT8 build on RX 6000 and RX 7000 cards without modified drivers, with release notes citing performance gains and reduced ghosting on RDNA 2.
- The community tool auto‑detects and swaps upscaling DLLs via an in‑game GUI and recently added support for Vulkan titles.
- AMD maintains it will not endorse the leaked INT8 path for older GPUs over quality and user‑experience concerns, even as Mark Cerny highlights that FSR 4.1 shares its neural network with PS5 Pro’s PSSR 2.
