Spoke to soon, soon as I got a dialog box pop-up from completing a mission the screen dimmed and the moving textures, flicking shadows and extreme light bloom issues came back...

It is almost certain that what ever is going on it is game side, I have tried three different driver versions using driver sweeper, checked and double checked temps, disabled Aero graphics, reinstalled the game, set all graphics options to zero in-game and in the Nvidia control panel, undid and even downclocked my graphics and CPU, all to no effect. IT IS NOT A HARDWARE NOR DRIVER ISSUE...
