What are the performance trade-offs between high and low-poly models?

The performance trade-offs between high and low-poly 3D models primarily involve detail, rendering efficiency, and resource consumption. High-poly models feature intricate geometry and textures for lifelike visuals but demand more GPU/CPU power and memory, often causing slower rendering or requiring higher-end hardware. Low-poly models sacrifice some detail to reduce resource usage, enabling faster rendering, lower memory load, and smoother performance on less powerful devices (e.g., mobile, low-end PCs). Use cases vary: high-poly suits static renders or detailed visualizations where realism is key; low-poly is ideal for real-time applications like games or AR/VR, prioritizing consistent frame rates.
