GPU Usage refers to how much work a Graphics Processing Unit (GPU) is doing at any given time. The GPU is responsible for rendering images, animations, and video for your computer or device. High GPU usage typically indicates that the system is processing demanding tasks, such as gaming or video editing, while low usage may suggest that the system is idle or running less intensive applications. Monitoring GPU Usage can help users optimize performance and troubleshoot issues. Tools and software can display real-time usage statistics, allowing users to see how efficiently their GPU is functioning. Understanding this metric is essential for gamers, designers, and anyone using graphics-intensive applications.
