Doom GPU Flame Graphs
AI Flame Graphs are now open source and include Intel Battlemage GPU support, which means it can also generate full-stack GPU flame graphs for providing new insights into gaming performance, especially when coupled with FlameScope (an older open source project of mine). Here's an example of GZDoom, and I'll start with flame scopes for both CPU and GPU utilization, with details annotated:
(Here are the raw CPU and GPU versions.) FlameScope shows a subsecond-offset heatmap of profile samples, wher...
