During GDC 2024, AMD made an exciting announcement regarding FSR (FidelityFX Super Resolution), its upscaling technology aimed at improving frame rates in games. FSR 3.1 brings anticipated enhancements in image quality and stability, accompanied by a shift in its positioning as a platform.
The key modification in FSR 3.1 is the separation of frame generation from upscaling, allowing compatibility with other upscaling solutions such as Intel’s XeSS or Nvidia’s DLSS. This change provides users with more control over performance, similar to DLSS, enabling a more customized gaming experience. As one Reddit user pointed out, this flexibility could be especially beneficial for older RTX GPUs by combining DLSS with AMD’s frame generation.
FSR 3.1 introduces a new API to promote developer adoption in the future. This API simplifies debugging and ensures compatibility with future FSR versions, addressing the slow adoption rate of FSR 3. Out of the 40 titles supporting or planning to support FSR 3, 21 fall into the upcoming games category, indicating that it is a developing ecosystem. AMD has also announced support for FSR 3.1 on two development kits: Vulkan and Xbox, hinting at improved console and handheld support in the future.
Regarding image quality improvements, FSR 3.1 focuses on enhancing stability during rest and movement, reducing flickering, shimmering, and visual artifacts around moving objects while preserving texture details. The first game to confirm FSR 3.1 support is Ratchet & Clank: Rift Apart, integrating the updated upscaling technology later this year and showcasing notable improvements in ghosting reduction and temporal stability.
