High Clip Plane
 

There isnt just one option in Eq2 like EQ1 where you can adjust how far you can see. While you can adjust how much land you see NPC's seem to be a different matter. It has something to do with the model count settings and such I think.

Was wondering if anyone figured out how to get the best seeing distance of mobs and land without maxing out all the graphic options.

You want:
Rendering distance - under performance
Level of Detail Bias - under Model Detail

Then from there you can mess with complex shader distance under Performance also although the higher that is the further ALL advanced effects will show up.
