Please be aware that a new Rockstar Games Launcher Update has been released for Grand Theft Auto V!
It does not change the version of either the launcher or the actual GTA5.exe.
In order to play with RagePluginHook you will need to launch Grand Theft Auto V either via Steam or the Launcher, load into Singleplayer, tab out and launch Rage.
It may take a minute to hook and freeze, but soon after it will still hook.
Despite what the RPH devs said though they weren't really very ... correct on when to load rage.
Basically if you dont wanna watch my stream, DO NOT load rage in story mode, load rage THE VERY SECOND the GTA window opens.
It is easiest if your on a BORDERLESS WINDOWED MODE graphics setting
Below is the best video that explains how to fix this
