Shadows (Grand Theft Auto 5)

The main question is: in Nvidia Experience configuring extended-range shadow rendering is somehow disabled and I have everytime to turn it on manually when entering the game, and is pretty annoying. Uyla if anyone had this problem and what was solved? The second question, but directly linked to the first: around the character a kind of field of drawing shadows. This is especially noticeable field while moving on the rails, and places with dense vegetation. Ie I just see at the distance of 7 meters all the shadows are loaded (from the grass, from the pillars and other things)
All options are set to ultra. (Except msaa antialiasing and grass, because grass wild procedi sometimes up to 15 - 20 fps and antialiasing not see the difference between x8 and x4 (exposed to the second option)
