## What it is
Spartan Engine is a C++ game engine built over 12+ years by a single developer, featuring a fully bindless, GPU-driven renderer with real-time path-traced global illumination and hardware ray tracing via Vulkan. It includes physics simulation at 200Hz, ECS architecture, and interactive demo worlds, and is positioned as a personal R&D project rather than a commercial product.

## Use cases
- study a modern GPU-driven renderer with bindless resources
- learn real-time path-traced global illumination techniques
- experiment with hardware ray tracing in Vulkan
- explore ECS-based game engine architecture
- prototype rendering research like ReSTIR GI and SSAO
- drive a car and interact with physics-enabled demo worlds

## When to choose
- you want cutting-edge, real-time rendering research code to learn from
- you need a reference for bindless, GPU-driven Vulkan rendering
- you're studying how a solo-built engine implements ray tracing and physics

## When to avoid
- you need a production-ready engine with support, roadmap, and tooling
- you're shipping a commercial game and need stability and ecosystem
- you require multi-platform support or a large contributor community
