New app injects AMD's AI-driven FSR Redstone framegen into unsupported games — pre-alpha OptiScaler build demo shows nice improvements over legacy FSR frame gen

A side-by-side comparison of a game showing FSR Redstone vs an older version of AMD FSR.

A Reddit user has demonstrated AMD’s new ML-powered FSR Redstone frame generation running in Monster Hunter Wilds. This game was never designed to support it; it used a community OptiScaler pre-alpha build to bypass official integration restrictions. The user, who shared their test on the r/radeon subreddit, shows side-by-side footage of an older version of FSR Redstone versus the newer Redstone ML frame generation.

AMD began rolling out Redstone ML frame generation more broadly earlier this week with Adrenalin 25.12.1, positioning it as a more advanced replacement for FidelityFX Super Resolution 3. Officially, Redstone requires newer FSR integrations and is tied to recent Radeon hardware. AMD’s documentation notes that FSR 3.1.4 adds the required camera parameter support that developers must implement to enable ML frame generation.
