Optick provides a seamless integration with Unreal Engine. Specifically designed plugin hooks into UE4 integrated profiling system and automatically collects all the events wrapped with QUICK_SCOPE_CYCLE_COUNTER macro. This plugin also includes all tools and features coming with Optick:

  • Thread Timeline View
  • Sampling
  • Switch-contexts
  • CPU Cores
  • Syscalls
  • Screenshots

You could download the latest version of the plugin here.

  1. Copy the contents of the downloaded zip archive into UE4 plugins folder:
    C:\Program Files\Epic Games\UE_4.22\Engine\Plugins\Performance\
  2. Launch UE4Editor.exe

⚠️ Optick uses ETW to collect kernel-level event (Sampling, Switch-contexts, CPU cores) which requires Admin Privileges to run. If you need kernel events - you'll need to run UE4Editor.exe(or VisualStudio) as administrator.

  1. Enable OptickPlugin: Edit => Plugins => Performance => Optick
  2. Click on the Optick button to open Optick GUI
  3. Press "Start Capture"/"Stop Capture" to start/stop profiling session
