The document introduces Intel GPA (Graphics Performance Analyzers), a tool that can optimize PC, mobile, and Ubuntu games. It summarizes the key features of Intel GPA, including its system analyzer, frame analyzer, and platform analyzer. The system analyzer monitors real-time metrics while gaming, the frame analyzer examines individual frames to find bottlenecks, and the platform analyzer shows CPU and GPU activity. Intel GPA allows optimizing games without code changes through experiments and analysis tools.
