The question of detail is a matter of perception more over it is an artifact of the Human visual system, in real life the amount of detail that can be perceived is dependent on the objective distance in relation too the viewer; that is to say that too the eye there will be more detail on a tree a distance of three feet than one at fifty or a hundred feet away given ideal viewing conditions.
There are many mitigating factors that govern detail and the amount of same that can be observed these include and are not limited too, Age of viewing subject (Visual Acuity decreases with age), Visual Anomalies in the eyesight of viewing subject such as impaired depth perception weather acquired such age, by birth or by other means, neurological particularly degeneration or injury too the Visual Cortex, other factors include line of sight and particularity obstructions between the viewer and the object been viewed, attitude difference between object and the viewer, meteorological phenomena such as fog, time of day and sun angle relative to the observers viewing angle among others.
There is a mechanism in the brain (I do not know its name, for the record) that protects us form sensory overload it acts as a filter preventing us from neurological distress the eye picks up a tremendous amount of detail, that we are not aware of, when absent the detail is missed: this then is the fundamental failing of CGI and why research in the area is ongoing too give our Augmented Reality via various means what nature and the ravages of time give us for free.
It is our artistic wish to capture a moment in time and freeze it for others who'd come after we have all long turned too dust and that dust has been scattered by the winds of ages may get a scene just for a moment of that moment in time. Our ancestors did it with the first cave painting over time the methods changed but the passion to create never has, need we defile their grace that long line of artists who have gone before or do we instead honor them and be thankful for what we have, despite its failings?
All good things come in time, the faults of TG2 are included in this.
