FSR 3 is an upscaling technique, creating high quality and resolution frames based on lower resolution input. By using this, your project can run in a drastically lower resolution without losing visual quality and increasing the framerate!
This Unity asset is created to interface with AMD's FidelityFX FSR 3 found here: GitHub - GPUOpen-LibrariesAndSDKs/FidelityFX-SDK: The main repository for the FidelityFX SDK.
If your project is limited by GPU performance, FSR 3 will give you a higher framerate. If a project is limited by CPU performance, all it will do is make the GPU workload lower. While this may seem like a big limitation, it also means a laptop will use way less battery power when using FSR 3!
