Architecture book ## PROFILING - Many Profilers used in Game Development Tracy, Intel VTune, Microsoft PIX, Custom • Need profiler with instrumentation • Need to see whole process and all threads Using GameDev - custom or 3rd party - many integrated into engine Used to measure CPU, GPU, etc Need profiler with instrumentation Cannot rely on sampling - everything is in jobs Need to see all threads dependencies Using VTune - best view for data building Presentation about Tracy profiler from CppCon 2023 An Introduction to Tracy Profiler in C++ CppCon 2023 ## TECHNIQUES ## KEEP THREADS BUSY Keep threads
