So on retail I set my view distance sliders down to 5. I didn’t like seeing the entire next zone, it makes the world somehow feel smaller, to me at least. So that was the first thing I did when I got into Classic–set the distance sliders to 5. I later put them back up at 10 and even then you can’t see nearly as far in Classic as you can on retail, and on Teldrassil at least there’s also a fog that helps obscure the distant terrain.
Everything else is cranked to the in-game max, except I disabled SSAO and AA for Reshade. Classic looks amaaazing with reshade, by the way guys.
