Use this if you have launching issues or visual issues on an AMD GPU. It might fix stuff for you but maybe it doesn't. This workaround could also work for other GPU's too.
ENB haves poor AMD support unfortunately and there's nothing I can do about it.


Installation:

1. Choose the right folder depending on your patch.

2. Replace enbseries.ini file from that folder with enbseries.ini from your GTA IV main folder.

3. Done.



In case you want to use the "Night Brightness Settings" optional or the "Graphic Quality" optional you can still do that
but you must change the following things inside enbseries.ini afterwards to enable the AMD workaround fixes:

-set "ForceNVidiaCard=true" value in the [GLOBAL] section to "ForceNVidiaCard=false"
-set "DetailMapEnable=true" value in the [DETAIL] section to "DetailMapEnable=false"
