AMD's Adrenalin 26.3.1 driver adds support for FSR 4.1 for Radeon RX 9000 series, along with Crimson Desert & Death Stranding 2 readiness.
AMD Just Silently Added Its Latest FSR 4.1 Upscaling Tech Support For RDNA 4 GPUs In Adrenalin 26.3.1 Driver Release
AMD's FSR 4.1 Upscaling technology has been much-awaited ever since its initial DLL files leaked out last month. Since then, modders have been able to get the tech working on RDNA 3 and even RDNA 2 GPUs, but with today's official release, the FSR 4.1 technology is officially enabled for Radeon RX 9000 GPUs. In addition to the FSR 4.1 support, the latest Adrenalin 26.3.1 driver also adds game support for the latest titles, such as Crimson Desert & Death Stranding 2.
With FSR 4.1, AMD brings sharper image quality across all ML-powered FSR games. But that's not all, AMD is also updating its FidelityFX suite with Ray Regeneration 1.1, which offers enhanced reflections and global illumination. These technologies are ready to try out in Crimson Desert.
- Ray Regeneration 1.1 – Enhanced reflections & global illumination, fully supported in Crimson Desert
- FSR Upscaling 4.1 – Sharper image quality for ML-based upscaling, delivering finer details and smoother camera motion across all ML-powered AMD FSR games
- Noticeable performance boosts in Ultra Performance Mode
Sony's Mark Cerny states that FSR 4.1 upscaling utilizes the same neural network that is implemented within PSSR 2.0.
