## FAQs
### Q: When was FidelityFX Super Resolution 3 released?
A: FidelityFX Super Resolution 3 was published on September 29, 2023. It was initially announced by AMD in November 2022.

### Q: Is FidelityFX Super Resolution 3 free to use?
A: Yes, FSR 3 is classified as free software distributed under the MIT License. This allows users to freely run, study, change, and distribute the software and its modified versions.

### Q: What technology does FSR 3 use?
A: FSR 3 utilizes real-time image upscaling and motion interpolation techniques. It is designed as a software library and image scaling algorithm to enhance visual output.

## Why It Matters
FidelityFX Super Resolution 3 represents a significant step in accessible graphics technology by combining real-time upscaling with frame interpolation. As a solution developed by AMD, it provides a mechanism for users to improve gaming performance and visual smoothness without relying on proprietary hardware locks, distinguishing it from some competitors.

Its classification as free software under the MIT License is particularly impactful for the developer community. This licensing model, confirmed for the FSR3 SDK in late 2023, encourages widespread adoption and integration by allowing developers to modify and distribute the code freely. By succeeding FidelityFX Super Resolution 2, it builds upon established temporal upscaling methods while introducing new capabilities designed to extend the lifespan of older hardware and improve the visual fidelity of newer displays.

## Notable For
- **Dual-Function Technology:** Combining both real-time image upscaling and motion interpolation into a single solution.
- **Open Source Accessibility:** Being distributed as free software under the MIT License, a permissive license that allows for broad modification and distribution.
- **Lineage:** Serving as the direct successor to AMD’s FidelityFX Super Resolution 2 technology.
- **Broad Compatibility:** Functioning as a software library that can be integrated into various development environments.

## Body

### Technology Overview
FidelityFX Super Resolution 3 is defined as an image scaling algorithm and software library. The technology performs two primary functions: real-time image upscaling and motion interpolation. These processes work together to render images at lower resolutions and then scale them up while generating intermediate frames to increase the apparent frame rate.

### Licensing and Distribution
FSR 3 is distributed under the MIT License. According to source references, the codebase is classified as free software, a status explicitly noted starting December 14, 2023. This ensures that the software is copyrighted but freely available for users to run, study, change, and distribute.

### Development Timeline
The technology was first announced by AMD in November 2022. Following its development phase, FidelityFX Super Resolution 3 was officially published on September 29, 2023. Detailed technical documentation and the software development kit (SDK) are hosted on GitHub and the official GPUOpen website.

### Relationship to Other Technologies
FSR 3 is a direct follow-up to **FidelityFX Super Resolution 2**. While FSR 2 focused on temporal image upscaling, FSR 3 expands upon this by adding frame interpolation capabilities. It is distinct from its predecessors through its inclusion of motion interpolation algorithms alongside its upscaling features.
