|
|

|
# Notes
|
|
This is a fork of [OneTweakNG](https://github.com/Nucleoprotein/OneTweakNG), containing additional fixes for FF13.
|
|
Thanks Nucleoprotein for starting this!
|
|
|
|
# Installation
|
|
Download the latest [release](https://github.com/rebtd7/FF13Fix/releases) and add both ```d3d9.dll``` and ```FF13Fix.ini``` to the folder ```FINAL FANTASY XIII\white_data\prog\win\bin``` for FF13 and to the folder ```FINAL FANTASY XIII-2\alba_data\prog\win\bin``` for FF13-2.
|
|
|
|
You can to change ```FF13Fix.ini``` if you want to change any configuration (e.g. uncap the framerate or disable controller vibration).
|
|
|
|
# What this does
|
|
|
|
## Removes the frame pacer
|
|
Disabling this greatly improves the frame rate in certain situations.
|
|
|
|
## Removes stuttering caused by new controllers being scanned every second
|
|
This caused stuttering specially if you didn't have a connected controller after the last opening of Steam.
|
|
|
|
Note that if you want to use a controller you need to connect it before opening the game (i.e. this patch removes the hotplugging support)
|
|
|
|
## Enables controller vibration
|
|
This can be enabled/disabled in the ```FF13Fix.ini``` .
|
|
|
|
## Uncaps the frame rate (optional)
|
|
Using higher frame rates can cause jankness on facial animations during ingame cutscenes.
|
|
See https://github.com/rebtd7/FF13Fix/issues/3
|
|
|
|
## Enables Triple Buffering
|
|
This may make the frame rate more consistent.
|
|
|
|
## Uses your desktop monitor refresh rate in full screen mode
|
|
By default the game forced a 60Hz refresh rate in full screen mode. With this mod the game uses the same refresh rate that you are using in your operating system.
|
|
|
|
## Changes to where the memory is allocated on certain vertex buffers
|
|
This considerably improves the frame rate when 2D elements are being disabled on the screen (i.e. minimap or battle menu HUD). This fix is not new, it is from [OneTweakNG](https://github.com/Nucleoprotein/OneTweakNG).
|
|
|
|
## Fixes misaligned screen space effects (fixes 1440p resolution)
|
|
|
|
## Fix the enemy scan text on resolutions over 720p (FFXIII only)
|
|
The game calls [SetScissorRect](https://docs.microsoft.com/en-us/windows/win32/api/d3d9helper/nf-d3d9helper-idirect3ddevice9-setscissorrect) using a rectangle hardcoded with the 720p coordenates. This correct the coordenates and rectangle size in order to fix it.
|
|
|
|
# Usage with the 4GB Large Address Aware patch
|
|
You may wish to patch the games to allow them to access more than 4GB of RAM. This seems to avoid crashes in FF13-2 (and may help FF13 under some configurations).
|
|
## FF13:
|
|
* Create a copy of the unpatched ```ffxiiiimg.exe``` to the folder ```FINAL FANTASY XIII\white_data\prog\win\bin```. Name it ```untouched.exe```.
|
|
* Patch the original ```ffxiiiimg.exe``` (you can use https://ntcore.com/?page_id=371)
|
|
## FF13-2:
|
|
* Patch ```ffxiii2img.exe``` (you can use https://ntcore.com/?page_id=371)
|
|
|
|
# Reporting issues
|
|
* Please specify what game are you talking about, which mods are you using (dxvk?) post system specs, and post FF13Fix.log
|
|
* Add a save file and steps to reproduce the issue if possible
|
|
|
|
# Other notes
|
|
* This is currently not compatible with GeDoSaTo.
|
|
* I strongly recommend forcing anisotropic filtering on your GPU driver to improve the quality of the textures.
|
|
* Using "Maximum Performance" power management in the GPU driver can also help keeping the frame rate smooth.
|
|
* If you are using ```dxvk```, rename its x86 dll file to ```dxvk.dll``` and keep FF13Fix as ```d3d9.dll```
