Use the mods that increase view distance and a Levitate spell and Vvardenfell was a pretty small island all in all.
Indeed, the first time I ever did distant land from MGE and booted up a save I had in Ebonheart and looked out across the water, I was completely dumbfounded by just how close Vivec was to Ebonheart. Seriously, with the fog (and the general fact that one wouldn't really think to swim from the Ebonheart docks to Vivec) you would think they were miles away from each other but they're not. It was crazy.
The difference between what you see from the top of a mountain and the grass is the LOD textures which look great from a distance, but have little detail. If you tried to render the individual blades of grass as far as you could see you would still be looking around at 2 FPS at that meadow. If you are on the PC, you can increase the fade distance and see more detail farther out.
Well I operate at max settings and its still just blech. I mean yeah it can't be uber detailed but it can't look like this either:
