AMD FidelityFX Super Resolution 2 (FSR 2) is an open-source, high-quality temporal upscaling solution that reconstructs high-resolution frames from lower-resolution inputs using motion vectors and depth data. It ships as a C library with compute shaders designed for integration into game engines and rendering pipelines.

Use cases

• upscale game rendering from lower resolution to 4k
• integrate temporal upscaling into a custom game engine
• boost frame rate without losing image quality
• replace TAA with a combined upscaling and antialiasing pass
• add FSR 2 support to a DirectX 12 or Vulkan renderer
• render at dynamic resolution and reconstruct full-resolution output

When to choose

• you need high-quality temporal upscaling in a real-time 3D application
• you want an open-source, vendor-neutral alternative to DLSS
• your engine can supply motion vectors, depth, and color inputs
• you target DirectX 12, Vulkan, or similar modern graphics APIs

When to avoid

• you need a drop-in driver-level upscaler for existing games rather than engine integration
• your pipeline cannot provide motion vectors or camera jitter
• you want the newer FSR 3 with frame generation
• you work outside real-time rendering (e.g., offline image upscaling)
