AMD releases their FidelityFX SDK 1.1 with FSR 3.1
AMD’s upgraded FSR 3.1 upscaler is now available to all game developers with the FidelityFX SDK 1.1
AMD has officially released their new FidelityFX 1.1 SDK, giving developers access to the company’s latest FidelityFX technologies through GPUOpen. With this release, AMD has given all developers access to their FidelityFX Super Resolution (FSR) 3.1 upscaling technology. Now, FSR 3.1 can be added to any game.
Alongside this new SDK update, AMD has also released a new FSR 3.1 Plugin for Unreal Engine. This updated plugin supports all versions of Unreal Engine 5, including version 5.4.
What is FidelityFX Super Resolution (FSR) 3.1?
AMD’s FSR 3.1 technology is the company’s latest temporal upscaling solution, which comes with its own Frame Generation component. With FSR 3.1, new changes have been made to the company’s Super Resolution tech to provide stronger detail preservation, increased temporal stability, and improved image quality.
Additionally, FSR 3.1 has now gained support for the Vulkan API. Beyond that, FSR 3.1 now allows users to enable AMD’s Frame Generation techniques with non-FSR upscaling solutions. FSR 3.1 also adds changes to deliver higher quality results and deliver better frame pacing.
Finally, FSR 3.1 must now be integrated through AMD’s FidelityFX API. This change enabled a fast upgrade path that will allow game developers to upgrade to the latest version of AMD FSR with ease. This is great news for both gamers and game developers. This change should allow more games to benefit from newer versions of AMD’s FSR upscaler. Note that this change should make FSR upgrade mods for games easier to create for titles that are not patches with official FSR version upgrades.
FSR 3.1 is a big deal for both PC and console gamers
The release of FSR 3.1 is a big deal for AMD. Not only does it increase the quality of AMD’s upscaling technology, but it allows their Frame Generation technology to be used alongside DLSS and XeSS. That’s great news for Intel GPU users and older Nvidia GPU users. Beyond that, AMD’s FSR upscaler is used heavily within the console space, making this updated FSR release highly relevant to console gamers.
While analysts still place FSR 3 behind DLSS and XeSS in pure image quality terms, AMD has clearly shortened the gap between FSR and its AI-based competitors. With AMD’s new FidelityFX API giving developers a clear FSR upgrade path, we can expect future versions of FSR to be adopted quickly and across a wide range of games. Will AMD’s FSR 3 tech catch up to DLSS? I guess we will have to wait and see.
