AMD FSR 2.0 deployment reaches Unreal Engine plugin library
This has been an important month for AMD super resolution technology called FidelityFX Super Resolution 2.0 (FSR).
AMD FSR 2.0 deployment is probably not as fast most gamers would want, however this might be about to change thanks to the newly released Unreal Engine plugins. The First FSR 2.0 games had only started to appear last month, but there are already (or only) four games that support this technology. A total of 20 games have already been confirmed to support this technology at some point in the future.
This week AMD is celebrating a one-year anniversary of FSR 1.0, a spatial upscaling technology that has been introduced last June. This anniversary has been celebrated with FSR 2.0 going open-source. Now all developers can implement this technology into their game free of charge.
AMD FSR 2.0 is based on temporal upscaling. This means that the implementation of FSR 2.0 will not be as simple as its successor, but for games that already have motion vectors and other temporal upscaling support (such as DLSS), the implementation will take days nor months, AMD claimed.
Unreal Engine already has temporal upscaling, which means that FSR 2.0 support might now be as simple as adding a plugin and optimizing it for the game. Temporal Antialiasing is actually a requirement for FSR 2.0 plugin to work. The FSR 2.0 plugin has built-in RCAS sharpening, which means that games that already had AMD FidelityFX-CAS implemented, this sharpening technology should be disabled beforehand. Conveniently, AMD provides an extensive guide how to achieve this, no matter if that’s 4.26.2, 4.27.2 or Unreal Engine 5.
AMD FSR 2.0 now joins NVIDIA DLSS 2.0 plugin for Unreal Engine 4 and 5, which means developers can now choose between two technologies or even support both.
