Overview

CryEngine features several methods of analyzing job performance at run-time as well as in offline mode.

• For a quick overview of the current worker load, use the console command Profile 1.
• For a more detailed overview used the Statoscope tool which can be found in the game_branch/Tools folder.

Profile 1

The console command Profile1 displays information of individual jobs and their execution time.

The feature should be used to get a rough overview. For a more detailed per frame analysis of data please refer to using the Statoscope tool.

(Note: Do not worry about the frame timings in this picture. The screenshot was taken in windowed + out of focus mode on PC)

How to use:

• In-game console command: Profile 1

Features:

Job Types:

• None-Blocking
• Blocking
• SPU (PS3 only)

Job title bar:

• Count: The number of executions in the sample frame
• Time_:_ The execution time of the job in the sample frame
• Function_: The job name_

Statoscope

Statoscope offers live as well as offline analysis of data on a per frame basis.

Link to the Statoscope Guide where more information about the tool can be found.

How to use:

Step 1:

• In the in game console type: e_StatoscopeLogDestination 1

Step2:

• In the console type: e_StatoscopeDataGroups YZ
• DataGroup Y = Job Information Individual
• DataGroup  Z = Job Information Summary
• (Note the capital letters)

Step3:

• Start Statoscope 

Step4:

• Click File->Connect

Step5:

• Connect to the platform the game is running on

Features:

Job Information Individual:

DataGroup: Y

Individual job stats for the various backend types for a given frame.

Backend Types:

• None-Blocking.
• Blocking.
• SPU.

For each job:

• ExecutionTimeInMs: The total time the job has taken to execute within a frame.
• NumOfExecutions: The total number of times this job was executed on one or several workers within a frame.

Job Information Summary:

DataGroup: Z

Summary of all job activity for the various backend types for a given frame.

Backend Types:

• None-Blocking
• Blocking
• SPU

For each backend:

• TotalExecutionTimeInMs: Total time spend executing jobs
• TotalNumberOfJobsExecuted: Total number of jobs executed
• TotalNumberOfIndividualJobsExecuted: Total number of individual jobs executed

sys_job_system_profiler 

This tool visualizes the job activity spread across the the different threads.

sys_job_system_profiler 1

Its broken down into 3 main sections:

• Main execution graph at the top that displays through different colours the jobs currently active and on which thread, Render / Main / Worker 0-7.
• The Main Thread Update in the bottom left
• Overview of the Jobs bottom middle, detailing the number of executions of the jobs, & time taken, waiting & average time in ms.

As you will notice, the execution time of the jobs is very fast, so you can pause the display at anytime (when in-game) with the Scroll Lock Key.

sys_job_system_profiler 2 is just the execution graph by itself.

sys_job_system_filter

You can filter out particular systems from being displayed to clean up the display and make it easier to read.

Eg: So if you were to type... sys_job_system_filter CBrushRender,WaterUpdate

You will remove these from the view. To add them back in, simply remove them from the above line. 

More than one job can be filtered by using a comma like the example above.

sys_job_system_max_worker 
This sets the number of threads to use for the job system.

• Defaults to 4 on consoles.
• Defaults to 8 threads an PC.
• Set to 0 to create as many threads as cores are available.

sys_job_system_dump_job_list

Print to the console a list of the available "jobs"
