The hotfix addresses the following issues only:

Platform Fixes:

• Fixed a Pure Virtual Error when transitioning between high resolution imagery and default scenery.
• Corrected floating buildings across multiple GPUs.
• Corrected batched scenery objects flickering across multiple GPUs.
• Corrected runway lights not rendering across multiple GPUs.
• Fixed an issue where AI aircraft would not correctly clear navigation settings. This would cause the AI to constantly overwrite control surface values being set by the user through SimConnect.
• Fixed a bug where scenery objects would not correlate across multiple views.
• Fixed shadow issues with GPU terrain and with bathymetry enabled.
• Fixed an issue where non-tessellated terrain would not respect ground detail flag.
• Corrected some textures appearing dull if the Scenario Setup screen was used.
• Fixed crash on shutdown when multiple devices were used.

SimDirector Fixes:

• Context menus will now correctly correspond to the clicked graph node in Mission Visualization.
• Fixed a crash related to saving and applying changes with a spinner box selected.
• Fixed a crash related to changing units with the Measure Tool.
• Fixed a crash when moving SceneryObjects.
• Scenario Visualization now displays an indication of loading for large scenarios.
• Fixed an issue that would cause event actions to generate invalid values of “: 0″.

Extract the appropriate zip file and copy the contained files on top of your default installation. You should accept all prompts to overwrite files (Yes or Yes to All).

The full Prepar3D download links will be updated in the near future to include this hotfix, but you are encouraged to use this hotfix patch whenever possible.

Please be aware, if any third party software modified any of the dlls included in the hotfix, you will need to reinstall their content/add-on. Additionally, when using this hotfix, any Prepar3D repair or reinstallation will need the hotfix reapplied.

To cool to use a few hours to spare, we set the head to see what version v2.5 Prepar3D was able to do with the two types of addons: those oriented Landclass and scenes Photo Reliable.

1. These two categories are represented respectively by Orbx one side and France-VFR another. The result is that now the two can coexist on the same simulator.

2. Show that P3D 2.5 digests very well in France Brittany 3DA-VFR (latest technology but showed worries about P3D v2.4). For Orbx, our previous test had shown that the answer was a long time: yes !.

Some pictures to get started:

My Settings

In the configuration panel of  NVIDIA:

1. General Tab put all parameters on "Default",
2. Prepar3D Tab, put all parameters on  "Default"

In the file  "Prepar3D.cfg", a variable has to be set on "1" because it removes the autogen poping and works perfectly on P3D 2.5 ... on v2.4, it was not tip-top

The P3D settings:

The two scenes "Bretagne VFR 3DA" provide an extensive autogen (but different from the autogen as defined by FSX, it is the 3DA standard of France-VFR). Fortunately, France VFR offers us three possible restitutions:

For small configurations (32bit OS): a basic version (in the "VFR Voln Britain - Objects layer")

For more muscular configurations (64bit OS) a complement (in the "Bretagne VFR Voln - Objects layer 64-bit"). The name has nothing to do with 64bit files, it refers to the OS.

For very muscular configurations of objects and trafficking contained in the "Extras" directory "Bretagne VFR Voln - Ground layer" to be placed in the "Scenery" of "Bretagne VFR Voln - Ground layer".

After various tests on my configuration ( I7 4770k 4Ghz, 4MB GTX780), it turns out that the best results are obtained for the flight by disabling 64bit scenes (keep declared for any screenshots).

The generosity of the object volume has a drawback: the loading time. My PC gets stuck on 6% in "Loading field data" a good number of minutes required for the digestion of what strength P3D him swallow, but the wait is worth it.

Some details about the settings "Scenery" essential to the display of scenes:

1. "Level of detail radius" determines the radius (in thousands of m) in which objects and autogen are loaded. We have shown that its size has much less influence on the framerate of P3D than that of FSX, so the smaller the radius is bigger and better is the aspect in P3D.

2. "Scenery complexity" is to the maximum base setting recommended for Orbx products and why not FVFR for maximum performance display.

3. "... Autogen density", these settings are to be changed depending on your hardware (but the point still has two maximum).

The rest of the settings is to your taste and the power of your hardware (which manages your taste in general!).

A video tite on the spot to show the behavior of 3DA:

The 3DA objects are displayed in the radius required normally to P3D: more incongruous appearances or disappearances.

Saying that P3D v2.5 provides only a lot of unnecessary problems (full install a hotfix and third party applications that are not yet updated) is going a little fast.
Although improvements of v2.4 are not included in the list published by Lockheed Martin, the proof is: the regional scene 3DA seduced us!

In our opinion, proper waste by P3D v2.4 (at least in standard P3D), the relatively long processing time of loading shows that P3D preparing "its works" (one of the more than 2.5) the objects provided by France -VFR.

So Orbx and 3DA products works together ! In addition the two coexist because if France-VFR kept the rider used to crush the management of autogen files already installed on the PC to place his AGX product that takes no account of Orbx, integrates Orbx in its definitions 3DA object identifiers (sic).

Now that a publisher does not want to share the economic market with each other, we do not care a bit and even much since there is a simple solution for these products to coexist harmoniously on our machines.

To restore this:

1 - Go to the directory Orbx here: "C: Lockheed MartinPrepar3D v2ORBXScriptsCustom.au"

2 - Copy Files:
       AutogenDescriptions.spb
       Materials.spb
       RoofDescriptions.spb
in:
       "C: Lockheed MartinPrepar3D v2Autogen"

WARNING

PThink to backup your file "api.dll" before the update in order to be force to reactivate votre P3D. If your licencse doesn't have been clear by the patch you should send and email to Lockheed Martin and wait .....

 - Active Sky Weather has some problems with this patch.

Finally the Prepar3D new version is released this night : the v2.5 is ready to download !

It is a compete version and NOT a patch so it will necessary to uninstall the actual version after saving your configuration files in order to become operational quickly.

To keep your license on your hard drive without to send an e-mail to LM, in order to obtain a new registration order the best solution is given by  Jean Maridor from Pilote-Virtuel.com:

1. Start a new installation of Prepar3D v2.4 over the existing installation,
2. When the installer asks you if you want to repair or to uninstal, select "uninstal" and Prepar3D v2.4 will be removed from your hard disk without altering your license;
3. It remains to install the v2.5 when the previous step will be completed..

So towards the Lockheed Martin web site to downlaod 10 Go of datas: http://www.prepar3d.com/purchased_downloads

Good luck

Tips and Trucks:

1 - Thinks to backup theses directories:

%PROGRAMDATA%Lockheed MartinPrepar3D v2
%LOCALAPPDATA%Lockheed MartinPrepar3D v2
%APPDATA%Lockheed MartinPrepar3D v2
%USERPROFILE%DocumentsPrepar3D v2 Files

2 - In v2.4 terrain.cfg was in the main sim folder. In v2.5 LM moved the terrain.cfg into this folder %PROGRAMDATA% Lockheed Martin Prepar3D v2

All you have to do is copy the terrain.cfg to the main sim folder. Install all your ORBX addons and copy the terrain.cfg back to :

%PROGRAMDATA% Lockheed Martin Prepar3D v2

thats it

3 - In the P3D.cfg, in order to reduce reloading of textures when changing views you change the following line from:

UseGlobalTerrainView=False
TO:
UseGlobalTerrainView=True

4 - How can i make the path to put in my aitraffic? Before, all was in Main section on Prepar3d.cfg

There is now a SimObjects.cfg file inside the folder.

%PROGRAMDATA%Lockheed MartinPrepar3D v2 

Search for “Path Configurations” in the Learning Center.chm for more information.

First release for 2015, Prepar3D v2.5 has been released as a beta-test version

Requested Features and Enhancements Implemented in Prepar3D v2.5

We are currently finishing development on the first update to Prepar3D v2 for 2015, Prepar3D v2.5.  This version has several rendering and performance updates, a few general platform updates, and a pretty substantial update to SimDirector, Prepar3D’s intelligent tutor, virtual instructor, and scenario generation tool.

We wanted to thank our development community, and especially our Prepar3D.com forum moderators Rob and Saul, for your continuous feedback and effort to help make Prepar3D v2 the industry leader in flight simulation and virtual instruction.

We will be sending a beta of v2.5 to our beta team this week, and once we are satisfied with v2.5 we will then release the update.

Due to folder structuring, v2.5 will not be available in Patch form. A fully install will be required. This should only effect this point upgrade from v2.4-v2.5, v2.5° should be in patches again.

I hope that this v2.5 version will be released as soon as possible

Two news freeware to improve effects during landings (on earth or water) on P3D v2.

Tested and validated on my PC, they went enrich my  Prepar3D v2.4 configuration

Prepar3D McCoy Water Landing Effect.

This package replaces the default water landing effect in Prepar3D. All airborne particles are effected by drag, the lifespan of some have been randomized for a slightly less uniformed look and emitters are adjusted for better frame rate. Three levels of intensity are included, Maximum, Medium and Low.

A short video is provided demonstrating two of the three versions. "Maximum" is assigned to a PBY Catalina and "Medium" is assigned to a Grumman Goose, the "Low" version only displays a wake and does not appear in the video. All effects are Public Domain and are free to use for any purpose without restrictions.

Textures and sound file included by Vince McCoy.

.

 
Prepar3D Mods--McCoy Ground Landing Effect For Prepar3D.

This package replaces four default ground effects: touch down, dirt, wheel wet and wheel snow. All effects are affected by drag and are offered in five levels of intensity, maximum, high, medium, low and minimum. These effects can be used in any combination so every aircraft in Prepar3D can be easily dialed-in.

Textures and three custom sound files are included covering dry, wet and Snow conditions audible only while its related effect is displayed.

Plus tips on system settings and camera views by Vince McCoy.

This two freeware can be find on all simulation web sites and also on http://www.flightsim.com with the search function using "effects Mccoy".

Since September 29, 2014, the fix v2.4 was delivered to the public. This new version of Prepar3D is a much stable version than before and brings a lot of new features.

Certainly, it is not perfect but with some changes we approach some idea of the simulation FSX only in DirectX 10 was beginning to grasp.

My old configuration v2.3 had be upgraded according Rob Ainscough advices (http://www.robainscough.com) and the patch v2.4 provided by L.M.

For me, it is THE best version for network game with multi-players
