Real-time rendering—the on-the-fly generation of screen images within millisecond frame budgets—is the defining technical challenge of interactive software development. Unlike offline cinematic rendering, game engines must produce each frame within 16–33 ms to sustain 30–60 fps, demanding highly optimized pipelines backed by programmable GPU hardware. Leading platforms—Unreal Engine 5, Unity (HDRP), Godot 4, and CryEngine—employ layered rendering architectures combining rasterization, hardware-accelerated ray tracing, deferred shading, and AI-driven upscaling. This paper systematically compares these approaches across performance, visual fidelity, hardware requirements, and scalability. A cross-engine feature matrix is presented alongside an analysis of emerging AI-enhanced rendering technologies (DLSS, FSR, XeSS). The findings provide practical guidance for engine selection and pipeline design across diverse hardware targets, from enthusiast GPUs to mobile and VR devices.
