Generic PRE-processing graphics mod?

I've been searching around a generic PRE-processing graphics mod. One that could conceivably add shadows (and spotlights) to a scene... things that CAN'T be done after the fact with a "post"-processor like ReShade.

The closest I've come to finding such a mod is the (now defunct) " ENB " graphics mod... which is not only ancient, but no longer in development, doesn't support modern graphics engines, and is only 32bit (where most games now are 64bit.)

I know there are custom mods for specific games, but there's always a game with no such mods.

Am I one a Fool's Errand? Any tips are appreciated ("Snark" is not.)

there is something like this...

github.com/mj-ehsan/NiceGuy-Shaders

NiceGuy Lamps: can be used to add custom point lights to your screenshots. Add up to 4 point lights with customizable color, brightness, location, optional fog, and optional screen space shadows with customizable soft shadows. Fog intensity, Specular reflection intensity, and Specular reflection roughness are fully customizable. Reflection uses GGX (all credit to LVutner) and Diffuse light uses Lambert model. Fog is fake. Not suitable for gameplay as the lights are in view space and will follow the camera movement instead of sticking to the world.

Sorry for the extremely late reply. Notifications were going to Spam.

I had to manually download the scripts individually from the editor b/c the d/l link gives you files that can't be read directly from the Shader folder.

Thx.
