Performance and bug fixes for the PC versions of FF13 and FF13-2

https://github.com/rebtd7/FF13Fix

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

Download the latest release 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).

Disabling this greatly improves the frame rate in certain situations.

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)

This can be enabled/disabled in the FF13Fix.ini .

Using higher frame rates can cause jankness on facial animations during ingame cutscenes. See #3

This may make the frame rate more consistent.

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.

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.

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

People use DXVK on Windows to work around crashes with recent AMD Navi cards. If you are using Nvidia on Windows, you probably don't need it.

• Rename DXVK's x86 d3d9.dll file to dxvk.dll. Keep FF13Fix as d3d9.dll.

You may wish to patch the games to allow them to access more than 2GB of RAM. This seems to avoid crashes in FF13-2 and FF13 (especially when using triple buffering, playing on 4K+ resolutions, using DXVK and/or Reshade, or using HD texture/model mods).

• Create a copy of the unpatched ffxiiiimg.exe to the folder FINAL FANTASY XIII\white_data\prog\win\bin. Name it untouched.exe.
  • This is not optional. You must keep an unmodified executable named untouched.exe in your bin folder.
• Patch the original ffxiiiimg.exe (you can use https://ntcore.com/?page_id=371)

• Patch ffxiii2img.exe (you can use https://ntcore.com/?page_id=371)

• Install ReShade first. Rename ReShade's d3d9.dll to ReShade32.dll; Install FF13Fix normally, keeping FF13Fix as d3d9.dll

• Install ReShade targeting Vulkan; enable it globally

• 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

• 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.
