FSR 4 Redstone - Upscaling for Unity v1.0.5 is an advanced upscaling solution designed to enhance visual quality and improve performance in Unity projects. Compatible with Unity versions 2021, 2022, 2023, and up to 6.4, this technology generates high-resolution frames from lower-resolution inputs, allowing games to run at reduced resolutions without sacrificing visual fidelity or framerate.
FSR 4 Redstone uses a high-quality Temporal Anti-Aliasing (TAA) system to eliminate jagged edges and improve image smoothness. Users can choose to apply only the TAA component if they prefer not to use upscaling. Unlike FSR 3, FSR 4 is not built on a compute shader backend and is limited to AMD's official hardware specifications. As a result, it is recommended to include FSR 3 as a fallback for devices that do not support FSR 4, and a 25% discount is offered for FSR 3 when FSR 4 is purchased.
The upscaler is optimized to reduce GPU workload in CPU-bound projects and significantly lowers battery consumption on laptops. It integrates seamlessly with Unity’s rendering pipelines—Built-in, URP, and HDRP—through a unified settings interface that supports all versions, including the free one. Additional features include a Settings Menu Creator for customizing UI menus and support for HTrace SSGI and HTrace Ambient Occlusion, which provide advanced lighting and shadow effects.

The FSR 4 Redstone upscaler is compatible with Windows builds and includes a free evaluation version with watermarks, allowing users to experience its full feature set before purchase.
