A total overhaul of the old Flawless Widescreen script for GTA V that has been dysfunctional for many months if not longer.
As before, it allows for fine-tuning of FOV per each view - first person, in-vehicle, ADS, and third person. It also allows to remove the pillarboxing at cutscenes at 21:9 and wider, although having the latter enabled may cause some confirmation prompts to disappear at 32:9 and wider until disabled.
Download and install Flawless Widescreen.
Download this script and unpack the archive.
Put its contents in the main Flawless Widescreen folder (usually \Program Files (x86)\Flawless Widescreen\).
Launch Flawless Widescreen, select Grand Theft Auto V (updated) and set everything to preference.
Tested the latest game version at 2560x1080, 3440x1440, 3840x1080, and 5760x1080.
