I would only play with the proper third person camera if I could, isometric lacks immersion for me. I only use the isometric because I have to for combat. There should be options for lower end machines to not render things past certain distances, most other games I play have this setting. I can definitely agree with the fog of war and perhaps make it so the detached camera can't travel so far. Being able to have a proper vertical view range would greatly help with this.
