FlyAgi Tweak Utility - Manual

Beitrag von Agi » Mi 10. Okt 2018, 19:02

This is going to be the tweak utility manual once finished. If something is missing I will add this later.

The manual is slightly outdated and some options are not available anymore in the current version 1.06 - if some options described here are not available in your tweak utility please just ignore them, I will update the manual later.

Main Menu

The utility main menu can be opened by clicking on the menu helper 'Tweak Utility Options' on the lower right corner of the screen or by using the FlyWithLua macros menu (X-Plane menu bar > Plugins > FlyWithLua > Macros > FlyAgi Tweak Utility). The main page gives access to the essential performance and visual tweaks and links to submenus if configuration items are more complex - I will explain the different submenus and what they can do later.

The utility will always store the menu page last opened for quick access to submenus so you will get back to the menu page you have been in before closing the main menu. The menu can be closed by clicking on the button 'Save + Close Menu' or by clicking on the helper again. In both cases everything will get saved.



The presets button offers some predefined settings. If it shows 'Custom Configuration' clicking on it will act as a reset button and it will reset the performance tweaks to 'Utility Defaults'.

The presets don't control all the stuff the utility can handle, they can set up all the important performance tweaks:
  • LOD Setting
  • Drop Compensation
  • FPS Target
  • Water Effects
  • Water Reflections
  • Clouds
  • Road Traffic
  • Fog (if X-Visibility is not installed or inactive)
If you don't want to use performance tweaks or if you want set up the utility to use X-Plane default values you can simply use the 'Sim Defaults' preset.


LOD ist the range for objects to be visible, higher range will decrease performance and lower range will increase performance. The LOD button can be used to set up a specified LOD value or to activate an automatic LOD control. The automatic LOD control will increase or decrease the LOD depending on frame rate.

Drop Compensation

The drop compensation will decrease LOD very quickly if frame drops occur and Auto LOD is active. You can switch this off or specify a threshold frame rate which triggers the compensation effect. The compensation frame rate will be set to a usefull default value if you change the FPS target so you should set it up only if needed and after you specified your FPS target.

FPS Target

The FPS target defines the target frame rate for the automatic LOD control. If the frame rate is higher than this value the LOD will increase slowly, if the frame rate is lower the LOD will decrease slowly - this way you can get stable frame rates within the capability of your hardware. If you want to fly at stable 30 FPS you should set the FPS target to 30, if you want to maintain 60 FPS you should set it to 60.

Extended DSFs

This button is more or less for testing. You can switch off the extended DSFs by pressing this button but this will cause a scenery reload to have an effect. If X-Plane does not seem to react any more just be patient and don't click around - this could cause Windows to suspect X-Plane to be crashed and then really cause a crash. If you want to disable extended DSFs permanently I recommend doing this in the Settings.txt as this value will not be saved by the utility (saving and restoring this tweak would increase loading times drastically).

Water Effects

You can switch on and off the water effects for getting a significant boost in frame rates.

Water Reflections

The water reflections can be handled using this menu item - This way you can enable water reflections even if you have set the reflection slider in the X-Plane option menu to the full left for performance reasons.


The clouds button switches between default X-Plane clouds and significantly faster modified clouds. The fast clouds are looking more natural in most situations and don't result in excessive GPU load when flying near, in or above clouds. Both cloud types are available with or without a white-out control - if you want to see clouds and scenery when flying trough them you should use the 'No White Out' variant of your prefered cloud type.

Road Traffic

The X-Plane road traffic still has a significant impact on performance so it can be disabled using this setting. There is a fast setting as well with decreased traffic visibility range, this is faster than default but still slower than off.


The fog button allows to increase or decrease the thickness of the fog. If X-Visibility is installed it will be replaced with a submenu for X-Visibility fog control. X-Visibility can be disabled there as well if you need manual fog control.

Shadow Control

Opens the shadow control submenu.

Aicraft Persistance

Turns per aircraft saving for some additional items on and off. If you set it to on, the following
stuff will get saved and restored for the current aircraft:
  • Fuel
  • Payload
  • Center of gravity
  • Fuel tank selector
  • Auto baro + gyro

Fuel Tank Selector

The fuel tank selector can automatically switch fuel tanks for aircraft without a fuel tank lever both position.

Auto Baro + Gyro

If on, the barometric pressure and the gyro compass will be set up and readjusted automatically.

Controller Calibration

Opens the controller calibration submenu.

Weight & Balance

Opens the weight and balance menu. The button can be configured to access some third party payload managers instead of the X-Plane default weight and balance menu.

Bird Strikes

Opens the bird strikes submenu.

Reset User Interface

Resets the interface configuration: FPS display, menu helper, status info state and status info position will be set to default values.

Info + Credits

Opens the info and credits submenu.


Opens the launcher submenu.


This button creates a synchronization file containing most of your settings. You should set this up once you have setup everything to your liking if you want to use the same setup in other aircraft as well. If you want to synchronize a new aircraft just load the aircraft and click on 'Synchronize Aircraft' and your settings from the original one will be loaded into the new aircraft.

FPS Display

Turns the FPS display on and off.

Status Info

You can change the position of the status report for avoiding conflicts with some third party aircraft configuration menu helpers and, if needed, make the status report permanently visible.

Menu Helper

Switches the menu helper on or off.
