Optick is a super-lightweight C++ profiler for Games.
It provides access for all the necessary tools required for efficient performance analysis and optimization:
instrumentation, switch-contexts, sampling, GPU counters.

Looking for 'Brofiler'? It has been renamed to 'Optick', so you are in the right place.

Windows (x64: msvc)	Linux (x64: clang, gcc)	MacOS (x64: clang, gcc)	Static Code Analysis

✔️ - works out of the box, ⏳ - in progress, ❔ - will be available soon for the certified developers

1. Copy 'src' folder from the repository or latest release to your game project
2. Add OPTICK_FRAME("MainThread"); macro to the main loop of your game and #include "optick.h" header

#include "optick.h"
...
while( true ) 
{
	OPTICK_FRAME("MainThread");
	engine.Update();
}

3. Use OPTICK_EVENT(); macro to instrument a function

void SlowFunction()
{ 
	OPTICK_EVENT();
	...
}

4. Edit optick.config.h to enable/disable some of the features in specific configs or platforms.
   (e.g. disabling Optick in final builds)

⚠️ If your Game uses dynamic linking and you are planning to use Optick from multiple dlls within the same executable - please make sure that Optick's code is added to the common Dynamic Library and this library is compiled with OPTICK_EXPORT define (Static Library won't work).
You could also use precompiled OptickCore.dll which is packaged with every release:

• Add include folder to the extra include dirs of your project
• Add lib/x64/debug and lib/x64/release to the extra library dirs of your project
• Copy lib/x64/debug/OptickCore.dll and lib/x64/release/OptickCore.dll to the debug and release output folders of your project respectively

All the available API calls are documented here:

Run generate_projects.gpu.bat from the root folder to generate project files.
Open solution build\vs2017\Optick.sln with samples.

Brofiler has been renamed into Optick starting from v1.2.0.
All the future development is going under the new name.
Cheatsheet for upgrading to the new version:

• BROFILER_FRAME("MainThread"); => OPTICK_FRAME("MainThread");
• BROFILER_THREAD("WorkerThread"); => OPTICK_THREAD("WorkerThread");
• BROFILER_CATEGORY("Physics", Brofiler::Color::Green); => OPTICK_CATEGORY("Physics", Optick::Category::Physics);
• BROFILER_EVENT(NAME); => OPTICK_EVENT(NAME);
• PROFILE; => OPTICK_EVENT();
