FF13Fix

Fixes for the PC version of FF13

Notes

This is a fork of OneTweakNG, containing additional fixes for FF13. Thanks Nucleoprotein for starting this!

Installation

Download the latest release and add both dinput8.dll and FF13Fix.ini to the folder FINAL FANTASY XIII\white_data\prog\win\bin.

The frame rate is uncapped by default, but as VSync is enabled it may be limited by your monitor refresh rate.

You can to change FF13Fix.ini if you want to use the ingame limiter to cap the framerate.

What this does

Removes the awful frame pacer

I don't see the point in it. It is overly aggressive.

I did not see any negative side-effect of disabling it.

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)

Fix the enemy scan text on resolutions over 720p

The game calls SetScissorRect using a rectangle hardcoded with the 720p coordenates. This correct the coordenates and rectangle size in order to fix it.

Uncaps the frame rate

I did not see any negatives on unlocking the frame rate, but your mileage may very. If you are having issues, edit FF13Fix.ini to cap the frame rate.

Enables Triple Buffering

This seems to make the frame rate more consistent.

Changes to where the memory is allocated on certain vertex buffers

This seems to improve the frame rate. This fix is not new, it is from OneTweakNG.

Uses your desktop monitor refresh rate in full screen mode

By default the game forced a 60Hz refresh rate in full screen mode. This patches this so the game uses the same refresh rate that you are using in your operating system.

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.
