Looking at the trailer, I am doubtful that it will need more than 4.84, but it would be handy to know if there is any increase in resources required to play the next modification in the series.
I ask this purely because my PC is on its last legs, I can run well outside of fights and loads of players in one spot, in fights though I turn all graphics off but object detail to attempt to get a lagless fight client side.
on the one hand things will run better ( due to the aforementioned optimization ) - on the other hand, there re options to add post rendering effects - which will then require a bit more CPU.
The game could be a little more demanding on the GPU (vid card) as many more effects have been added to the game as well as a few features. However, the difference will be really minor and it is still possible to change the quality of the ingame graphics while activating the mod and while ingame (like 4.84).
And dito the other, yes, a few things have been optimized, but I don't know how much. So in the end, you have a pros and a cons, which makes 0 together:D
