So we were talking about how the new xbox has roughly 10 times the CPU power of the old one.
What does it really mean?
I was using an open world game as an example, say it has the draw distance of 1KM.
The open world game will have to render 360 degrees of the world, so it has to render an area of 1KM^2 X Pi = 3.14KM^2.
So if I I have to render an area with radius of 2KM, how much more CPU power do I need?
2KM^2 X Pi = 12.57KM^2 (stuff to render)
12.57/3.14 (2KM / 1KM) = 4
Wow, to double the distance, I will need 4X the CPU power!
So 10X CPU power gives you
sqr of 10 = 3.1623KM
That means, when we 10X the CPU power, the world is 3.16KM instead of 1KM in an open world game...
This refutes Ben's article - Endless open worlds
Of course this is pure maths, and there are plenty of interesting things you can do to increase perceived draw distance.
Ok, one last maths equation
if I increase 1KM to 100KM draw distance, how much more CPU power do I need [trollface]
100^2 * Pi = 31,415 KM to render
31,415 / 3.1415 = 10,000 X CPU Power - that's a lot of CPU power
TLDR - 10X gives you around 3 times more rendering in an open world game. To render 100X more distance, you need 10,000 times CPU power.
