Is there a good reason to enable vertex lighting?

[Insidious]

All of the guides that I’ve seen for this game online all have the same “copy and paste this into your .ini” solution. They all also have the line “DisableLight” in the text, which, if you look in the options menu, enables vertex lighting, which makes lighting in areas dim, or there will be no lighting at all, making some things look unusual.

For some reason, it also causes Dr. Ort-Meyer’s blood in the ending cutscene to appear black instead of red. I was just wondering if there is a “good” reason to keep it enabled, aside from the downside that Ort-Meyer’s blood will be black? Does it benefit the game or the game’s performance in some way? I have tested it myself and I don’t see a difference in framerate.

you should keep it off, it causes glitches.
