Will you still use graphics enhancing mods with elder scrolls games when games look so realistic mods dont improve the game only change them stylisticly?

Depends on how you define graphics enhancing. Because things like overly illuminated caves are a design decision that Bethesda will probably not abandon, I'm sure lighting overhauls will remain necessary. Except for the horrible lighting, Skyrim's graphics are actually good enough for me already. I don't use any texture mods or anything. I use RCRN, an ENB and the Imaginator to change lighting, contrast and saturation a little bit as well as add depth of field.

There are already mods that offer different styles for lighting, enb settings and (female) bodies. So, seeing as how offering different choices for different tastes is already a big thing today, i don't see how the answer to the op's question isn't plain obvious.

I'll definately download a mod that removes "fake lighting", which bothers me to know end, and one that removes the blue tint that nights have in bethesda games (Green in Fallout 3). There are so many aesthetic choices in bethesda games that irritate me that I'll always want changed, and these have nothing to do with the art style of the game specifically.

I don't use them now.

Those "realistic lighting" mods are about the only ones I care about.
