Optick is a very lightweight performance profiler, which provides easy access to the most critical performance toolset and metrics: timeline view, instrumentation, sampling, switch-contexts data, and GPU counters. Optick has already proven itself as an indispensable tool and is used on a regular basis by a number of well-known video game companies around the world. Check https://github.com/bombomby/optick for more details.

Optick goes with a special plugin for UE4, which provides seamless integration between Optick and Unreal Engine - no need to compile or build anything. It is literally plug-and-play!

Optick automatically picks up all the standard UE4 instrumentation macros (e.g. SCOPE_CYCLE_COUNTER) so you can easily instrument any custom code, modules, and plugins. Profiling has never been so easy and fun.
