Complex setup, but game looks good.

1. Open game launcher (runs by default). Click Options. Set Resolution to your single-screen (if your resolution not available, not a problem). Set Renderer to dx9, graphics how you want. Click OK.
2. FOV Fine-Tune (part1, optional, recommended): Click Launch, get to player view (that's the first checkpoint). Measure player's full height with ruler, jot it down.
3. Quit from Launcher or from in-game (whichever is open).
4. SoftTH (fullscreen, DX9, x86).
5. Flawless Widescreen (FWS).
A. Current game version required (v1.3, seen in game's launcher & main menu. Exact build-version likely doesn't matter, FWS is smart).
B. Install game's plugin & checkmark all. Ignore resolution, FOV value 0.0, then quit.
C. Menu Etc Fix:
i. Find (path-to-FWS)\PluginCache\FWS_Plugins\ Modules\LANoire\Dependencies\ Scripts\LANoire.lua.
ii. File edit (Notepad): Replace string "DisplayInfo:GetAspectRatio()" with "####/####" (no quotes, your width / height), save.
6. Start FWS, enter your fullscreen resolution & click Enable OFF & back on (every time). Open game launcher & click Options again. Set Command Line to -windowed. Click OK & Launch Game. Game should launch with no errors, as small 1280x720 window (if not, quit & fix *). In-game select massive resolution & apply (every time).
7. ShiftWindow (+ border = borderless & to position).
8. Mouse Clipping Fix (optional, recommended if using mouse): PrimaryLock utility limits mouse movement (instructions in guide/parent page).
9. FOV Fine-Tune (part2, optional):
A. Use Alt+Tab to adjust FOV value in FWS, on the fly. Zero looked ~proper in testing.
B. To confirm proper FOV is rendering, compare player height against jotted (can't go by position, as camera is offset).

NOTES:
1. Game's Hor+ & FOV looks proper. HUD & menus perfect (except Pause **). FMV cutscenes fill all screens (not stretched, slight vert-, LLL would be more vert-), while rendered video varies: either centered & bit hor+ (mostly story cutscenes; these spread to 40% of side screens) or perfect spread (mostly close-ups & interviews, often interactive).
2. Minor issues:
A. ** Pause-menu usually has bottom entries cropped off (not a problem): Social Club (maybe), Options, Restart Case, Exit. These are accessible with keyboard. E.g. To quit from menu top, press up-arrow once, which rolls off-screen to Exit at menu bottom (down-arrows work fine too.)
B. In-game camera in casual-view is anchored bit higher than original. But this looks as good & doesn't affect gameplay. Aim-view is perfect. Driving's basically perfect (car's angle maybe slightly different, may depend on which car).
C. Loading screens basically correct, though background texture is vert-.
3. FWS must be restarted to recognise edits. Should backup lua file. If game menu expands in future, paste file back in.
4. * Game Startup Fixes, for these cases (sometimes FWS doesn't hook right):
A. Restart game if game disappears, or immediately game abends, or logo screens are vert- & your window is PLP.
B. Restart FWS & game if Windows error message, or your resolution is not visible in-game menu.
C. If still problem, restart PC to clear it. Don't run game as Administrator.
(comparison. Camera is noticeably offset in only this view. FOV is about proper.)
