I know what I'm talking about, which is something that cannot be said about "bigspleen", who btw is a user that registered today only to complain.
Actually a potential GT6 on the PS4 could max it right away: on this genre things can get pretty demanding. The discussion is if GT6 on PS4 would be a better game than it on the PS3, besides improved graphics (that won't be a night and day difference anyway, considering hardware and assets).
And what will compete with forza5 on the graphics side of things is Drive Club, which blows forza4 and gt5 away. That's sony's staple for release date, and hopefully pCars makes it to both next gen consoles so there's a direct comparison there too.
No you clearly are clueless.
The ps4 has share and online functions that come with the console ps3 cannot do.
The ps3 was dated 4 years ago, and kaz himself complained how it held his vision back, you know more then him?
Ai and physics are very CPU intensive, that is fact, and having more of it would allow Kaz and team to really leverage the ps4 hardware to make a way more advanced physics and driving engine.
The extra memory would allow way more freedom to cram way more detail, content into the game. Ever wonder why shadows, day and night, damage is so limited in GT5? Ps3 limited ram that's why. Ask Kaz he said the limited ram was an issue.
This is nothing more the GT5 spec III, a cash grab.
The ps4 is akin to a high end PC right now, there is a MAJOR leap from ps3 to ps4, saying otherwise shows your clueless. MAny devs have stated this, I'll take their word over yours.
The unified archiecture of the PS4 further gives develpers way more to work with. Devs with more to work with = better games.
