If you don't use TAA, this preset is not for you. This preset aims to reduce the blur that's associated with TAA by sharpening the image. TAA does a great job at devouring the jaggies, but the blur is almost as bad as having the jaggies! This preset should help a ton. If your GPU can handle it, try turning up the resolution scale. That should help with some of the unwanted earthquake effect that's also associated with TAA. I spent 45 minutes trying to find the most pleasing values. If I find that it needs further tweaking, I'll make a V2 preset.
Download and install ReShade ver 3.0.6 or later @ https://reshade.me/
During installation, when it asks you about downloading shaders, say Yes and select only LumaSharpen.
Download the preset and stick it in the RE7 root directory.
Load up the game and follow the ReShade tutorial.
Download this .rar file and extract its files to your RE7 root directory.
EDIT: There's been a report of the game failing to launch when it's in fullscreen mode. Possible fix is to use borderless windowed instead. I haven't had an issue like this. Only issue I've had is the controls sometimes not responding after launch. Alt-Tabbing out and back in fixes this usually, but sometimes it doesn't. Kill the process via Task Manager and relaunch. That should clear it up.
EDIT 2: If your game still refuses to launch, remove your current version of ReShade and try an older version. 3.0.4 has been reported to work in RE7.
