Diag Menu – DayZ

The Diag Menu is a menu listing many options used to debug game scripting and assets. It is available in the diagnostic version of the game executable (DayZDiag_x64.exe).

Usage

• To open the Diag Menu, press ⊞ Win + Alt (alternatively, Ctrl + ⊞ Win but this shortcut conflicts with Windows 11's shortcut) in any 3D viewport
• To enter a sub-menu, press →
• To leave a sub-menu, press ⟵
• To change a value, use ← and →.

ⓘ

When available options are being shown, it is in the order they are listed in the menu, the first usually being the default.

ⓘ

Some options may require you to be able to use your mouse on the screen.

This can be toggled by pressing Ctrl + NUM 9

This key binding is registered through script. (PluginKeyBinding)

Any mention of "Cheat Inputs" are inputs hardcoded on C++ side.

FPS

Enables the showing of FPS in the top left corner of the screen.

ⓘ

The FPS is calculated from the time between last 10 frames.

Script profiler UI

Turns on the on-screen Script Profiler.

ⓘ

For more information regarding the script profiler, also read the documentation in EnProfiler.c.

⚠

This will only profile script, proto methods are not measured as separate entries. They will however add up to the total time it takes to run a script method when it is called inside one.

Section	Info
Time per class	The total time of all function calls belonging to this class. Shows the top 20 times.
Time per function	The total time of all calls to a function. Shows the top 20 times.

ⓘ

For Stats and settings it is best to also read the following "Script profiler sessions" and also EnProfiler.c.

Script Profiler UI

A set of settings to tweak the gathering of script profiling data.

ⓘ

These can also be tweaked by script through the EnProfiler API.

It is recommended to first read the documentation here before using the API.

For more information regarding the script profiler, also read the documentation in EnProfiler.c.

⚠

The EnProfiler API and the script profiler itself are only available on the diagnostic game executable.

Always Enabled

Gathering of script profiling data is not enabled by default, this bool displays whether it is currently enabled or not. If it is desired that the script profiler is enabled at start, the launch parameter "-profile" can be used to achieve this.

ⓘ

EnProfiler API Related:

• EnProfiler.c : enum EnProfilerEnabledFlags
• EnProfiler.c : EnProfiler.Enable
• EnProfiler.c : EnProfiler.IsEnabled

⚠

Do note that the Script Profiler UI does not care about this bool and will always force the profiling to happen as long as the on-screen UI is visible.

So when the Script Profiler UI is turned on, it will not set this bool to true, since as soon as the UI is turned off, the profiling stops again.

Which is why the name is "Always enabled" and not "Currently enabled".

Flags

The set of flags that define how data is gathered.

Available options	Info
SPF_RECURSIVE	Data is gathered from the currently selected module and its children Data is per frame
SPF_RECURSIVE	Data is gathered from the currently selected module and its children Data is accumulated across frames
SPF_RESET	Data is only gathered from the currently selected module Data is per frame
SPF_NONE	Data is only gathered from the currently selected module Data is accumulated across frames

The meaning of flags:

• SPF_RECURSIVE: Enables profiling of child modules (recursively goes through them)
• SPF_RESET: Enables the clearing of data at the end of the frame (resets the data)

ⓘ

EnProfiler API Related:

• EnProfiler.c : enum EnProfilerFlags
• EnProfiler.c : EnProfiler EnProfilerFlags methods group

Module

The module to be profiled.

Available options	Info
CORE	1_Core
GAMELIB	2_GameLib
GAME	3_Game
WORLD	4_World
MISSION	5_Mission
MISSION_CUSTOM	init.c

ⓘ

EnProfiler API Related:

• EnProfiler.c : enum EnProfilerModule
• EnProfiler.c : EnProfiler EnProfilerModule methods group

Update Interval

The amount of frames to wait before updating the sorted data. This also delays the reset caused by SPF_RESET.

ⓘ

Available options: 0, 5, 10, 20, 30, 50, 60, 120, 144

ⓘ

EnProfiler API Related:

• EnProfiler.c : EnProfiler.SetInterval
• EnProfiler.c : EnProfiler.GetInterval

Average

Enable/disable the displaying and returning of averages. Of course, when the SPF_RESET flag is present and there is no interval, this will be the value itself.

When SPF_RESET flag is not present, it will divide by the session frame. When an interval is set, it will divide by the interval.

Class count will never be an average, it will always be the current count of the instance, allocations will be the average value of how many times an instance was created.

ⓘ

EnProfiler API Related:

• EnProfiler.c : EnProfiler.EnableAverage
• EnProfiler.c : EnProfiler.IsAverage

Time resolution

Set the time resolution to display time in. This is in the form of nth of a second.

So that means that 1 means in seconds and 1000 means in milliseconds.

ⓘ

Available options: 100000, 1000000, 1, 10, 100, 1000, 10000

ⓘ

EnProfiler API Related:

• EnProfiler.c : EnProfiler.SetTimeResolution
• EnProfiler.c : EnProfiler.GetTimeResolution

(UI) scale

Sets the scale of the on-screen script profiler UI. Simply because there are different screens and resolutions, and this way you can tweak it to be better visible if necessary.

There is no EnProfiler API equivalent for this, as it is purely for the on-screen UI.

ⓘ

Available options: Range: Start: 1; Min: 0.5; Max: 1.5; Step: 0.05

Lighting

The following toggles toggle the respective lighting.

Ambient lighting

Toggles the general ambient lighting.

Ground lighting

Toggles the lighting reflected from the ground. Noticeable difference is on the roof and the character's underarms.

Directional lighting

Toggles the general directional lighting of the world. Without this, the bidirectional lighting is actually also turned off, as it depends on this.

Bidirectional lighting

Toggles the general bidirectional lighting of the world.

Specular lighting

Toggles the specular lighting. Noticeable differences are on the side of the cupboard and on the car.

Reflection

Toggles the reflection lighting. Noticeable differences are on the side of the cupboard and on the car.

Emission lighting

Toggles the emission lighting.

Shadows

Enables/disables shadows. Additionally, this also disables the culling of rain inside of objects.
