The tools allow for support of any display aspect ratio and real-time FOV adjustment in Death Stranding. The gameplay and engine-rendered cutscenes will properly fill the screen, while the state of the pre-rendered cutscenes will depend on the used solution.

Option 1:
A trainer automatically detecting any resolution and allowing to make the zoomed pre-rendered cutscenes 16:9. Left alignment of the pre-rendered cutscenes is a known issue. The tool also allows to adjust FOV at any aspect ratio.
Unpack the archive - the password is pcgw Launch the game, followed by the trainer Press the desired keys - ideally from the main menu and before any cutscenes Go to Graphics Settings and select your resolution under 21:9 Option 2:
The known ultrawide solution made into patchers limited to common wide resolutions and keeping the pre-rendered cutscenes zoomed.

Tested the latest Steam version at 1920x1080, 2560x1080, 3440x1440, 3840x1080 and 5760x1080 (HUD is spanned).

I may have been the first to discover the common sense aspect ratio change solution (as seen on the WSGF Discord), but I am certainly not the one who published the bytes first (looks like it was FasterThanFTL). As such, I am not taking any credit for the patchers but you can buy me a coffee for the trainer based on many hours of 100% unique research, calculations and code.

Kudos to LowSpecGamer whom documented the Wayback Machine archive link on his video about the game.
