Analyzing Resource Performance in a 3D Virtual Immersive Environment

Abstract

This paper presents a comprehensive approach to performance testing in 3D virtual reality applications developed using Unity, with a focus on continuous evaluation and optimization throughout the development process. The methodology started with an immersive 3D application over four versions and used native tools from the Unity engine (Profiler) to measure specific performance metrics, such as CPU, GPU, memory, audio, video, physics and UI usage. This approach allowed for early identification of problems (bottlenecks) and continuous optimization of the application at each stage of development. The main results include significant improvements in memory usage, reduction in the number of batches and triangles rendered, and adjustments to the physics that resulted in improvements in the frame rate. The study also highlights the importance of balancing visual fidelity with performance optimizations, and that continuous performance testing is essential to create optimized immersive applications, emphasizing the importance of initial profiling and iterative improvements.
