Why would we be talking about Astrophysics on here Howard??
LOL
Anywho...
I know you mostly play Nintendo but if you can not see the difference between the capabilities of say a PS3 and a PS4 you need your eyes testing!
Even games released close together, Say Battlefield 4 looked substantially better on the 4.
You are looking at the advancements wrong.
You cant compare the jump in GFX from a 2600 to SNES and then a XBox to a XB1.
Where are they meant to progress? 4D??
You say the changes are small but that’s what’s needed.
We need the little details, The individual hairs, The textures etc.
And those things take time and power.
The purpose of me starting this thread was to point out how far GFX have come in the last 40 years.
We have gone from as you say block turd to almost realistic (I said almost Howard we all know it’s not perfect yet
)
Who’s to say in another 40 years it wont be photo realistic with us unable to tell the difference?
Hell another 40 years we may even have photo realistic VR!?
Maybe re-read my OP especially the bit about my elderly friend and have a think on that?
