wtf is dbd-reshade?

This repository presents itself as a visual enhancement tool for the game Dead by Daylight, using a technique called ReShade. ReShade is a well known post processing tool that changes how a game looks on screen, such as adjusting colors, sharpness, and lighting, without changing the actual game files or how the game plays. According to the README, the tool adds color correction, sharpening, contrast changes, and lighting adjustments to make the game look cleaner, while trying to keep the performance cost low. It lists several customizable visual presets and states it works on Windows 10 or 11 with a fairly modest computer, needing at least 4 gigabytes of memory and a graphics card roughly equivalent to an NVIDIA GTX 750 Ti or AMD Radeon R7 360. Importantly, this repository does not contain visible source code. There is no programming language listed for the project, and the README's only real content is a description, some screenshots, and a link to download a zip file containing an installer program that you would run on your own computer. The README states the tool is external and does not edit game files directly, but because the actual installer and its contents are not present or reviewable in this repository, there is no way to verify from the repository itself what the installer does. The README also includes a long list of search engine keywords related to Dead by Daylight visuals, which suggests part of the page's purpose is to be found through search rather than purely to document code. It ends with a note describing the project as being for testing and educational purposes only. Because there is no source code to review, non-technical readers in particular should treat any download link in a repository like this with caution, the same way they would with any executable file from an unfamiliar source, and verify the publisher and file before running it.
