One thing i notice that is quite common with modern AAA graphics heavy titles, is that including the uncanny valley effect of the 'near realism', they often, even on very high end hardware, get 'sticky' or non fluid when the screen gets busy.
It obviously is down to the engine, and is not always the case, but for example when you see the adverts on TV for Call of Duty and all those big budget titles, they often look odd because of this relative lack of smoothness of the action.
When you play you notice this less, but watching other people play you can really see that we are pushing some hardware limit in the ability to shift polygons around consistently smoothly with the sheer 'weight' of GB's needed in modern textures and graphical construction.
I fully expect to see all this in Star Citizen as more game footage is released. It is much less obvious in Limit Theory and so far (let's see how it develops) Elite: Dangerous has looked nicely fluid and sticky free in the few early vids we have seen in it action. However the more detailed you push your graphics the more this will creep in.
