Overview
- Optiscaler’s new release, reported as version 4.0.2b on GitHub, targets Radeon RX 6000 cards with performance gains and significantly reduced ghosting.
- Users report generally positive results so far, with smoother output and fewer artifacts compared with earlier community builds.
- The tool automates DLL swapping and exposes controls via an in‑game GUI, removing the previous need to install modified drivers.
- Access relies on INT8 FSR 4 libraries exposed by a leaked upload, distinct from the official FP8 implementation intended for newer RDNA 4 GPUs.
- AMD says it will not commit to supporting the leaked INT8 variant due to quality-control and user‑experience concerns.
