## What it is
AMD FidelityFX Super Resolution (FSR 1.0) is an open-source spatial upscaling solution that produces high-resolution frames from lower-resolution inputs using edge-preserving algorithms. It ships as shader code plus a DX12/Vulkan sample application for integration into game rendering pipelines.

## Use cases
- upscale game rendering from lower resolution for better performance
- integrate spatial upscaling into a DirectX 12 or Vulkan engine
- improve frame rates for costly effects like ray tracing
- sharpen and upscale rendered frames with minimal quality loss
- study open-source upscaling shader algorithms

## When to choose
- you need MIT-licensed, vendor-neutral upscaling you can embed in any engine
- you target DX12 or Vulkan and want a lightweight spatial upscaler without temporal data
- you want to boost performance on GPUs without proprietary upscaler support

## When to avoid
- you need temporal upscaling with motion vectors and better quality (FSR 2+ or DLSS)
- your project is not real-time game rendering
- you cannot integrate custom shaders into your pipeline
