Recommended Settings for Prepar3D® v1

Below are the recommended settings for Lockheed® Martin Prepar3D® v1, based on our own experience, assuming that your computer meets the minimum system requirements. Please note that some of these settings, such as the unlimited fuel option, are required for the X-15A-2 SE addon only, due to its custom fuel management system that bypasses the simulator's own fuel management system. Of course, these settings may vary from system to system and experimentation is required.

Refer to your simulator's documentation for more details.

Known Issues in Prepar3D® v1

The font used in the system monitor panel may appear jagged in Prepar3D® v1. This seems to be a minor simulator issue. We don't know of any fix at this time.

If the special visual effects don't look like the images in this documentation, refer to "Special Visual Effects" for some options.

If you have a widescreen monitor and feel you are too close to the main panel in the virtual cockpit even after zooming out or moving the seat aft, we recommend using a wide-view aspect ratio (see "Settings - General" above).

Note: The special effects for Prepar3D® v1 are optimized for a wide-view aspect ratio. If you are using a standard-view aspect ratio, the effects may appear too small (or too thin). To solve this issue, simply replace the default effects with the ones included in the "FSX Steam Effects (1.65)" folder contained in the Special Effects Package. Visit the "Downloads" section on our website and download the Special Effects Package. Read the instructions included with the Special Effects Package. Refer to "Special Visual Effects" for more details.

Optional Settings

Other optional settings require that you modify the "Prepar3D.CFG" file located in "C:\Users\your name\AppData\Roaming\Lockheed Martin\Prepar3D". It is not Xtreme Prototypes' policy to modify the user's "Prepar3D.CFG" file during the installation process. So this needs to be done manually by the user.

Should you decide to change these settings, please make sure that you've made a backup copy of your original "Prepar3D.CFG" file and saved it in a safe place before proceeding:

To prevent the dynamic head movement in the virtual cockpit under strong acceleration, which may be very distracting when flying the X-15, you can make the following changes:

[DynamicHeadMovement]

LonAccelOnHeadLon=0.000000

LonAccelOnHeadPitch=0.000000

RollAccelOnHeadLat=0.000000

YawAccelOnHeadLat=0.000000

RollAccelOnHeadRoll=0.000000

MaxHeadAngle=0.000000

MaxHeadOffset=0.000000

HeadMoveTimeConstant=0.000000

If you own a powerful computer equipped with a high-end video card, you can make the following changes to optimize the graphics (note that the X-15A-2 SE addon uses 2048 x 2048 textures):

[Display]

TEXTURE_BANDWIDTH_MULT=80

[Graphics]

TEXTURE_MAX_LOAD=2048

[Graphics]

TEXTURE_MAX_LOAD=4096

Note: If you still experience performance issues after optimizing your simulation platform, you may need to upgrade your computer system. Refer to "Minimum System Requirements".
