# lsfg-vk-afmf
**Linux Native Frame Generation using AMD FidelityFX SDK**

## Project Overview

This project aims to replace the Windows-dependent `Lossless.dll` in the existing `lsfg-vk` project with AMD's open-source FidelityFX SDK, creating a truly native Linux frame generation solution.

## Current Status ✅

**Phase 1 Complete**: Foundation build system working
- ✅ Compiles to `liblsfg-vk-afmf.so` (61KB)
- ✅ GitHub Actions CI/CD validated
- ✅ C++20 compatibility fixes for older toolchains
- ✅ Complete API migration from LSFG to AFMF

**Phase 2 Next**: FidelityFX SDK integration

## Quick Start

### Build Locally
```bash
cd lsfg-vk-afmf
./build.sh
# Output: build/liblsfg-vk-afmf.so
```

### Requirements
- CMake 3.22+
- Clang 14+ or GCC 12+
- Vulkan SDK
- Ninja (optional, faster builds)

## Goals

1. **Eliminate Windows Dependencies**: Remove reliance on `Lossless.dll` and DXVK translation layers
2. **Native Vulkan Implementation**: Use FidelityFX's native Vulkan backend for frame interpolation
3. **Enhanced Performance**: Leverage AMD-optimized shaders and algorithms
4. **Cross-Platform Compatibility**: Create a solution that works natively on Linux
5. **Open Source**: Provide a fully open-source frame generation implementation
