A new update of GTA5 Redux is out that allows it to work with the latest version of GTAV (1.0.1180.1).

v1.2.1
* lowered pedestrian spawns
* updated gameconfig.xml

Since GTAV received a recent update to 1.0.1180.1, Redux would not work until ScriptHookV is updated. However this has now been resolved and GTA5 Redux now works again.

Fresh Install

To install GTA5 Redux v1.2.1 download the full installer and follow the installation guide.

How to Update an Existing Install

Update ScriptHookV
