AMD Expands FSR 4 Support to 85 Games with New Driver Update, but Requires RDNA 4 GPUs

AMD has expanded support for its FSR 4 upscaling and frame generation technology with the release of the latest Radeon Adrenalin Edition 25.9.1 driver update. The update adds FSR 4 compatibility to 85 games, primarily those that already support FSR 3.1, thanks to improved driver-level integration. However, full functionality remains restricted to RDNA 4-based Radeon RX 9000 series GPUs. According to AMD’s official patch notes, the new driver enables FSR 4 as a drop-in upgrade in most DirectX 12 titles that previously supported FSR 3.1. The process is designed to be seamless: after updating to the latest Adrenalin Edition driver, users with a Radeon RX 9000 series GPU will automatically gain access to FSR 4. To activate it, users must first set their in-game upscaling to FSR 3.1, then enable FSR 4 through the AMD Adrenalin software interface. This allows the driver to override the game’s native FSR 3.1 implementation with the newer FSR 4 version. Despite this expansion, AMD’s FSR 4 still lags behind Nvidia’s DLSS in terms of game adoption and overall flexibility. DLSS benefits from deeper integration with game engines and broader support across titles. In response, the community has developed third-party tools like OptiScaler, which can redirect existing upscalers—including DLSS, XeSS, and FSR 2—into FSR 4 with frame generation, effectively extending FSR 4’s reach beyond official support. Additionally, some developers on GitHub have demonstrated that FSR 3.1 games can be manually upgraded to FSR 4 by replacing the game’s FSR 3.1 DLL files with those from AMD’s FSR SDK 2.0. While this method works in some cases, it’s considered unofficial and may lead to instability or compatibility issues. AMD continues to push FSR 4 as a key component of its graphics strategy, especially as it seeks to compete with established upscaling solutions. The latest driver update marks a step forward in making FSR 4 more accessible, though widespread adoption will depend on both developer support and hardware availability.
