## What it is
AMD's FidelityFX SDK (FSR SDK) is a collection of heavily optimized GPU techniques for DirectX 12 and Vulkan applications, including super resolution upscaling (temporal and ML-based), frame generation, and frame interpolation swapchains. It ships as a C++ SDK with samples for integrating these rendering technologies into games.

## Use cases
- upscale low-resolution game frames to higher resolution with FSR
- generate interpolated frames to boost game frame rates
- integrate ML-based upscaling into a DirectX 12 or Vulkan renderer
- implement frame pacing with a frame generation swapchain
- reduce GPU load in games by rendering at lower resolution
- add temporal anti-aliasing and sharpening to a rendering pipeline

## When to choose
- you are developing a DirectX 12 or Vulkan game or engine and want AMD FSR upscaling or frame generation
- you need vendor-supported, heavily optimized GPU rendering techniques with samples
- you want ML-based upscaling or frame interpolation without building it yourself

## When to avoid
- you target graphics APIs other than DirectX 12 or Vulkan
- you need a general-purpose image upscaler outside real-time game rendering
- you require a permissively licensed library and cannot work with AMD's SDK license terms
