This project studies the possibilites and challenges of NVIDIA Mesh Shaders. With custom meshlet based backface and frustum culling a comparison between Mesh Shader, Compute Shader and standard Vertex Shader is conducted to evaluate possible performance gains, pitfalls and obstacles.

A personal secondary purpose of the project was to implement a C++ framework from ground up using Entity Component System. The EnTT library was used for this.
