Open-source engine projects for profiling

By Gabriel C. Ullmann, 2023.

How we use these projects

• BaseGame: an "empty" project with one scene and nothing else. When run with Callgrind, it allows us to see the call graph of Godot "core" without the interference of other feature-specific calls.
• Pong: a sample project we intend to compare to the empty project in the future.

Profiling Results

Here you can see examples of .out files generated by Callgrind and trees drawn by KCacheGrind:

• Godot projects: empty, pong
• "Hello world" projects: hello-c, hello-java
• Other game engine projects: minestest, shervanator, urho3d
