Non-functional requirements (NFR) are characteristics that specify the quality criteria and constraints a system must meet. These requirements are essen-tial for the successful development of software, particularly in 3D mobile applica-tions, as they have a direct impact on user experience. Graphics performance is one of the most critical NFR in this type of application, as it affects both user ex-perience and the viability of these applications on devices with varying hardware capabilities. This paper examines the impact of NFR on 3D mobile applications, particularly focusing on the main variables influencing graphics performance, such as 3D modeling, texture usage, lighting, visual effects, and physical effects. Additionally, an experiment is presented on 3D mobile applications with and without virtual reality environments, where the impact of different features on the frames per second rate is evaluated. The results obtained help identify the main bottlenecks in one of the most critical non-functional requirements, contributing to optimizing performance and improving the overall quality of 3D mobile appli-cations and virtual reality environments.
