ENB with DXVK for GTA IV

What GTA IV version to use for ENB

Version 1.0.4.0

·        Better performance, better look

·        CONS: on some GPUs/drivers may initialize graphics and load game very slowly, no FusionFix

Version 1.0.6.0+ or EFLC

·        Has more robust video initialization routine. May work better than 1.0.4.0 for some GPUs/drivers.

·        New shadows implementation, better look but GPU-demanding.

·        FusionFix v1.10 works

In general you may use any GTA IV version. The guide was successfully tested on:

·        GTA IV 2020 Complete Edition properly downgraded* to 1.0.4.0 and 1.0.7.0. *Vanilla 2020CE 1.2.0.X without downgrade may also be used but for AMD GPU make sure that enbseries.ini has ForceNVidiaCard=false or else ENB won't be able to initialize display.

·        GTA IV Razor1911 original release upgraded to 1.0.4.0 and 1.0.7.0

Disclaimer: author does not take responsibility if your modified game does not work. Before doing any modifications DO make a backup of your game folder (the one that contains GTAIV.exe).

 

ENB installation

·        d3d9.dll from DXVK or SweetFX must be renamed or else it will be overwritten by d3d9.dll from ENB. Any unique file name will do, I will use d3d9_dxvk.dll for this guide. If you have d3d9.dll from SweetFX installed rename it as d3d9_sweetfx.dll.

·        Read mod description (usually readme.txt), select correct source folder for your game version and copy mod’s files to game folder

·        (For 1.0.6.0+ only) install or reinstall  FusionFix . This should be done last as copied ENB files may contain bugged gta_emissivestrong.fxc shader file. 

Examples below are for iCEnhancer 3.0 Natural as it is most popular one. They are identical for all other ENBs I tried (Simple ENB, Excellent ENB, Masterpiece ENB, Zimmer’s Z_Graphics).

ENB configuration for DXVK

Check [PROXY] section in enbseries.ini and make sure it is set as follows:

EnableProxyLibrary=true

InitProxyFunctions=true

Next select DXVK chainloading method for your game version.

DXVK chainloading for 1.0.4.0

In [PROXY] section in enbseries.ini set

ProxyLibrary=d3d9_dxvk.dll

If ProxyLibrary in enbseries.ini is already set to dax.dll do not modify this and read below.

 

DXVK chainloading for 1.0.6.0+ or EFLC

ATTENTION: ENBs for 1.0.6.0+ have ProxyLibrary in enbseries.ini set to dax.dll. This is helper dll by Dax1 which adds custom shaders to 1.0.7.0/EFLC 1.1.2.0. Do NOT modify this setting. If you replace dax.dll with DXVK’s dll all in-game shadows will disappear!

Dax.dll has its own chainloading configuration in file DX9Settings.ini (you must create this file if it is absent. Easiest way is to save file from Notepad as DX9Settings and then change .txt extension to .ini in Explorer). Put the following into DX9Settings.ini:

[General]

DumpAll = false

ProxyLib = d3d9_dxvk.dll

OverrideMethod = 0

 

Launch the game.

 

Using SweetFX with ENB and DXVK

SweetFX may be used in conjunction with ENB for antialiasing and other custom shader effects. This multilevel chainloading is not recommended though as ENB has its own built-in antialiasing and custom shader effects.

·        To disable built-in ENB antialiasing you must set EnableEdgeAA=false in enbseries.ini

·        SweetFX’s d3d9.dll must be renamed as d3d9_sweetfx.dll

Set up chainloading for 1.0.4.0

Enbseries.ini (ProxyLibrary=d3d9_sweetfx.dll)  -> 
  SweetFX_settings.txt (// external_d3d9_wrapper = d3d9_dxvk.dll)

If the above scheme doesn't work then remove or move away SweetFX's dxgi.dll if you have it. If it still doesn't work then rename ENB's d3d9.dll as d3d9_enb.dll and SweetFX's as d3d9.dll and try

SweetFX_settings.txt (// external_d3d9_wrapper = d3d9_enb.dll) -> 
  Enbseries.ini (ProxyLibrary=d3d9_dxvk.dll)  

Set up chainloading for 1.0.6.0+

Enbseries.ini (ProxyLibrary=dax.dll)  ->  
  DX9Settings.ini (ProxyLib = d3d9_sweetfx.dll) ->
     SweetFX_settings.txt (// external_d3d9_wrapper = d3d9_dxvk.dll)
