Overview

A top-down arena game built from scratch with no third-party engine. I engineered its rendering pipeline for both PlayStation 5 and Windows: OpenGL and GLSL on PC, and the PS5 rendering API (AGC) with PSSL shaders on console, behind one C++ codebase.

The game runs a timed arena level with collectibles, obstacles and a live frame-time overlay.

Highlights

  • Cross-platform rendering pipeline for PlayStation 5 (AGC, PSSL) and Windows (OpenGL, GLSL)
  • Deferred lighting added to the existing PBR system, with 64 GPU-instanced point lights and 1 directional light
  • Instanced repeated objects such as walls and bounce pads, cutting draw calls by 42% (550 to 315)
  • Graphics debugging with NVIDIA Nsight Graphics and Razor GPU
