Open-Source AI Flame Graphs: Now with Intel Battlemage GPU Support

Intel has open-sourced AI Flame Graphs, adding support for Intel Battlemage GPUs. This allows for the generation of full-stack GPU flame graphs, providing unprecedented insights into gaming performance. Using GZDoom as an example, the article demonstrates how FlameScope, combined with CPU and GPU flame graphs, can pinpoint performance bottlenecks. By visually comparing CPU and GPU activity, developers can quickly identify areas for optimization. The example highlights CPU shader compilation time and GPU performance variations across different game scenes. While setup requires a Linux system and some kernel/library tinkering, the powerful analysis capabilities make this a valuable tool for game developers and performance engineers.
