Desempenho do Design Orientado a Dados com Unity DOTS

Abstract

The efficiency is an eternal quest in the world of software development, particularly in extreme scenarios such as games. Data-Oriented Design (DOD) has emerged as an alternative approach to the well-established Object-Oriented Design (OOD), providing better paths to achieve highperformance results. This work aims to compare the performance of these two approaches using Unity DOTS, which is a series of packages added to the Unity engine that enables game programming using Data-Oriented Design. Two versions of an experimental game were created, one using OOD and the other using DOD, and were subsequently subjected to tests on three PCs with varying hardware configurations. The results showed a significant performance gain with the DOD approach. However, in scenarios where the PC experiences a GPU bottleneck, the gain is limited to improved hardware utilization and does not impact the FPS (frames per second), as the frame generation is delayed by the GPU rather than CPU workload.
