CivilWolf's RE7 Widescreen Patcher (Obsolete. Use REFramework Nightly. Link in comments)

Here are the common Hex values. Look for you monitor and type it on the aspect ration section

https://www.wsgf.org/article/common-hex-values

Instructions

1. Unzip and launch the patcher. (Locate In-game Folder and select re7.exe)

2. Enter your screen width and height. (or aspect ratio: 16:9 - width = 16, height = 9)

3. Locate the game's executable file.

4. Once the patch is completed you may close it and launch the game.

You may have to press Alt+Enter when the game launches for the first time after you patch the game for it to take effect.

I added my own screens (3440x1440) with my own Reshade Preset (Let me know if you want it here), CivilWolf's RE7 FOV Trainer (110), Remove Vignette with the DLC campaign (No Hero; Chris and End of Zoe; Joe Baker) and some of the other modes like Banned Footage: Nightmare/Bedroom, Jack's 55th Birthday.

Remove Vignette (No Black Shadows on the sides of your screen; WTF were you thinking Capcom for putting this on all new RE games; RE2R-RE3R-RE7)
