An Introduction to Tracy Profiler in C++
summary
Tracy is an interactive C++ profiler that actually shows a timeline, not just aggregates: nanosecond resolution with measured timer costs like ~4 ns on some Intel chips and ~41 ns on an M1, pushes millions of events per second, and mixes manual instrumentation, selective sampling and automatic sampling. The demo compiles client code, connects to a server, profiles Quake with OpenGL GPU+CPU correlation, captures call stacks to about call-stack depth ~60, logs messages, plots values and tracks allocations.
