# Doom GPU Flame Graphs

**[Brendan Gregg's Blog](https://daily.dev/sources/brendangregg)** · 8 min read · 1 upvotes · 0 comments

## Summary

AI flame graphs are now open source, allowing for detailed analysis of gaming performance on Intel GPUs, including Battlemage. By analyzing CPU and GPU flame scopes side by side, patterns in utilization and performance can be identified efficiently. The example using GZDoom highlights how CPU and GPU flame graphs reveal insights into resource management during gameplay. The Intel open source accelerator profiler, iaprof, facilitates GPU profiling but requires complex Linux setup with specific hardware and drivers.
