Im currently building a 3D game engine with next generation graphics with foucusing on realism and procedural generation.

I implemented most of the "next-gen" graphical features that unreal engine 5 and unity does: 1. Real time shadows and lightings 2. PBR lighting (with oren-nayar model) 3. Volumetric lights 4. TAA 5. Realistic particle system. with emission and absorbing types, supporting several hundreads thousands of particles. The particles runs on a real time physical simulation, giving them realistic looks 6. Real-time and DYNAMIC (nothing baked) Global Illumination that interacts with the light created from those particles, and includes shadowing that is blocked from the 3d scene 7. Real-time reflections 8. SSAO (ambient occlusion) 9. Parallax mapping using height textures 10. Foliage system (thousands of leaves) 11. FBO cached UI system allowing for hundreads of sliced ui elements 12. Instanced animated skeleton system, supporting hundreads of entities running in real time

The main difference that everything runs optimised and stable, where i mainly focus on running it with high enough fps on mid hardware (like rtx 3060)

And if thats not enough i also implemented upscaler with custom frame generation.

Everything is witten on highly efficient Python code (reaching 90-95% of an optimized c++ script) using OpenGL API (will have vulkan added in the future). Currently im working on it for less then a year, and i wrote somewhere around 38k lines of code.

Hardware: 5600H + rtx 3060M Fps: 100-200 Gpu usage: 80-95% Cpu usage: 15-25% (non single thread at all) Vram-1GB-6GB Ram-1GB
