About This File

This AVSIM Prepar3D Guide will cover the following topics to help users get the most of Lockheed Martin’s Prepar3D platform.  Some of the information in this guide is applicable to prior versions of Prepar3D (V2.x and V1.x), however the primary focus of this guide will be for Prepar3D V3.x onward:

  •           Installation and purchase
  •           Updating to a more recent Version
  •           Configuring Graphics Settings
  •           Working with Configuration Files
  •           Configuring 3rd Party Add-Ons
  •           SimConnect
  •           Troubleshooting
  •           Hardware, Overclocking, Performance
  •           Input Control Devices (TrackIR, Yokes, Throttles)

The basic flow of this guide will take you thru; basic purchase and installation process, how to update your Prepar3D installation when new versions are released, configuring your graphics settings, exposing what settings increase process loads, adjusting you 3rd party products configuration settings to improve performance, some Prepar3D configuration settings (often called “tweaks”), setup of SimConnect (used by many 3rd party products), working thru compatibility with older FSX products, a quick guide to basic overclocking, and finally setting up input control devices (controllers).

This document will assume limited computer experience, but it will cover both easy and advanced topics.  Parts of this document will expect users to understand how to use a text editor (like Notepad) to edit/modify content in text files.

Hopefully there is some information to be gain in this document for the new user and the experienced user.

One fantastic piece of work.  Thank you so much Rob, you have made incredible contributions to the P3D community in the past and continue to do work for us for which we are all grateful.

Rob, your user's guide is excellent. It's the "missing manual".  Amazing amount of work (read: huge, detailed and comprehensive) for the community, my hat's off to you...almost makes me want to get P3D right now (seriously).

I echo the sentiment above Rob....Again thx a million..seriously. 

 

I have questions regarding two newly identified tweaks

  • ENABLE_MEMORY_OPTIMIZATION =1
  • MaintainSystemCopyOfDeviceTextures =0

Seemingly by adding both of these to the Pd3.cfg I've benefited largely (primarily with VAS returns and marginally FPS improvements).  I have both set as above

Is that right? 

Thx

This is a really good, In-Depth Guide. I tried the tweak MaintainSystemCopyOfDeviceTextures   Unfortunately that tweak causes me to OOM so I dont use it ;)

I have no AffinityMask tweak in my Prepar3d.cfg.

Used the search function and found nothing..

Try searching for AffinityMask in the Prepar3D Forum.  We have many experts on this tweak.

I have a link to Steve's AM thread in my guide ... see page 48.

 

Cheers, Rob.

Yes, that is the preferred setting in "most" cases.

 

Cheers, Rob.

somebody did a wonderful job here and diffidently deserve a credit for this.

 

I'm sure lot of Simmers are very pleased with the fact that they got something that will keep them busy for few hours/ days 

 

But, honestly, is there a way to get and use this Uber-Sophisticated Sim without spending hours /days of going through something that for the common Simmers,(IMHO), is meaningless ( terminology and technical speaking) , it is overwhelming and quite depressing to think that you do not have the skills and capabilities to understand or to master most of the stuff in the guide, & thus you are doomed.... I'm trying to thing about the tedious amount of affords need to be put whenever LM coming with an update, and you need to figure out why your Sim ceased functioning as it use to and which "Part" of the Software is to be blame for .. (go chase after 3ed Party addon guy bagging for help) ....

I'm here to fly. or maybe I'm wrong defining the purpose of Flight Simulator ??? 

Should I find another hobby or what  ???

 

 

  Cheers 

 

... friend handed me a key to his Austin Martin  DB9, show me few features of this marvels Puppy, and 10 minute later I was looping on the race track ...sweet ...... I guess a Flight Simulator require a bit more to have fun , ha ...lol

Hi Bob,

Thanks for your efforts. Its a pleasure to read a document that is very well written and illustrated as it is not always common. One only has to look at instruction manuals today to find some bad examples.

Cheers
