This is a new mod I just stumbled upon, by accident. I haven't tried it yet, I just got my new monitor and I haven't finished modding my SSE yet. I do not know about the impact performance on low end machines either.
I'm posting it here for people to try, and maybe, eventually, submit a STEP proposal to be included in the guide, if it's aesthetically pleasing and within the mandate of S.T.E.P., of course. :)
