Walkthrough Fix for Crashes, Errors and Low FPS Issues

This is a simple Walkthrough Fix for some of the Game Crashes, Errors and Low FPS Issues currently happening in Hyperdimension Neptunia Re;Birth3 as of 02-11-2015.

General Contents

After having done some research, I managed to find a solution for most crashes and low FPS issues.

It seems like the reasons as to why the error and crashes appear, as well as the low FPS on some occasions are all due to several programming faults within the ReBirth3.exe file.
The .exe file doesn't have the correct instructions on what to use of the OS, and just pushes the default instructions out, which eventually cause the game to crash or have a low performance.

-
The most common issue, as people have previously pointed out, is the 2gb RAM cap.
It seems that the .exe is instructed to stay bellow a 2gb RAM usage; which in turn will lead to a crash once a heavier scene appears.

The way to fix this is by changing the code in the .exe file and forcefully make it so that it uses 4gb of RAM or more.

The CFF Explorer program used in order to fix this can be confusing, and for the people that (like myself) don't really want to install it just to be able to play the game, through this link you will find a Patch, which is written by the developer's of the CFF themselves, that will change the code of any .exe you want from having the 2gb RAM cap to being able to use 4gb or more:

http://www.ntcore.com/4gb_patch.php (64bit only)

Just download the zip, run the executable, choose the ReBirth3.exe file to patch it and you'll be all set.
This Patch will also automatically make a backup copy of any .exe file you choose, so you'll always have a safe version.

This way you will get the ReBirth3.exe fixed without having to install the CFF program or run through all the steps.

-
Now for the next issue, it seems like the ReBirth3.exe file is also instructed to run on a integrated graphics card by default instead of changing to a dedicated one in most Laptops.

An example for this is having a Intel HD Graphics 3000 as the integrated one and a NVIDIA GeForce GT 540M as the dedicated one in my case.

The ReBirth3.exe is under the instruction to never trigger the usage of the NVIDIA card, unlike ReBirth1 was, and will always run on the Intel card, causing the FPS to drop bellow 30 on a constant level or even crash during heavier loading scenes such as the common Plutia battle one.

-
In order to fix this you will have to manually add the ReBirth3.exe file in your NVIDIA control panel and choose to run it in a high-performance NVIDIA processor setting by following these steps:

1. Open the Windows Start Menu
2. Enter “NVIDIA control panel” into the Search field and run it
3. Select “Manage 3D Settings” from the option in the left-hand panel
4. Select the "NeptuniaReBirth3.exe" to change the graphics processor for the game under the "Select a program to customize" option
5. Select your NVIDIA graphics card under "preferred graphics processor" instead of the default “auto-select”
6. Click Accept and you should be all finished

With this, the next time you launch ReBirth3, this should properly trigger your dedicated graphic card instead of your integrated one.
Not to mention that you should now be able to play the game at a stable 60FPS and without any crashes.

-
It should also be of notice that you should have the latest Visual C++ components and graphic drivers up to date in order for everything to function properly.

-
At this present moment with these fixes am I am able to run ReBirth3 on my old laptop without any major issues, so I hope this simple guide will help you run it as well.

Thank you for reading.

This is a useful tool to have, thanks for this guide!

The patch works. I just did it on the GOG release and it got me past the point where it would crash just as Plutie transforms into Iris Heart for the first time and opens up a can of whoopass.

for being an Old guide, this probably won't work. so i need to explain.

after trying to download the 4GB Patch for Rebirth 3, i couldn't seem to be able to use it to run Rebirth 3. there are no Visible changes and the Game still Crashes during Chapter 7 right as Anonydeath is revealing Yellow Hearts Identity.
Next i tried using the NVIDIA Control Panel method and that didn't help either as the game Still Crashes during the same Scene. I've also tried downloading CFF Explorer but that wasn't working either.

does anyone have any advice on how to fix any of this? thank you

Me compre el re1 re2 y re3, aun estoy jugando el 1 pero como mi gráfica es una intel hd3000, me fui descargando el re2 y re3 para ver si funcionaban, el unico que me dio problemas fue este juego, gracias a este parche ya lo solucione. Gracias

Hi, I know this post is from 2015, but I'm usually late.
I have an AMD Ryzen 5 4600g and I am outraged that I cannot play a game like this with such a machine.
my integrated graphics are Radeon graphics and I have 16 ram.
the game crashes and closes automatically, the same thing happens with REbirth1 and 2. and this solution didn't work for me... is there something I can do?

everytime I apply this fix, I get a weird error where the game is run n some super low rez mode, so low rez I can't read anything on any menu to fix it. Maximizing the game's resolution from this won't fix it, only reverting the Patch will. and without the patch the game keeps crashing in Jet Set Range in Chapter 2, I can't get through the area without crashing while fighting foes there.

TThanks! this fix my crash. It kept crashing on afroire first appearance. Nothing new from Idea factory and compile heart pc ports...

[SoriPhoono]

the 4 GB fix fixes crashing due to programmatical space in the computers RAM, the graphics card fix helps performance! thanks for posting

Apparently if you update the game, or whenever you update this game, you'll need to reinstall the 4gb patch again for the game to work again, for some strange fyi. Just as a head's up.

I applied the 4gb RAM upgrade for this game, and now it no longer crashes at a particular point. Thanks for the guide, man!
