If there's a "controller friendly" control system but who are separated from the wheel users online etc and with splitscreen for family/friends who don't like using the superior wheel controls, this would be a day 1 buy.

Not many options otherwise on ps4, driveclub has no splitscreen which for me is a deal breaker despite looking fantastic, and project cars and f1 2015 are not controller friendly, and not atm interested in GT sport unless I see a great improvement from gt6.

Why is this because they had to work around the weaker hardware structure in PS4?

Its like this if your game is being made with DirectX what ever version..

Its going to be the basis of the performance unless you are making your game with Sony's

GNMX in mind. Than its reverse. The performance basis will not be based on DirectX.

Common sense people!

Example:

PS4 IS SUBSTANTIALLY BETTER THAN XBOX ONE EVEN WITH DIRECTX 12, SAYS STARDOCK CEO

Remember its not just about Raw Performance power, Game theory, and design, the developers & teams skill, the experience they have with the system, the money investment into the project, and Time..team size. Many factors.

If a developer has been coding for PC with DirectX as their main Graphics Api..if their game Engine is based on Using said DirectX why would people expect the PS4's performance to be up to par with that outright unless you redesign the Engine or graphics Api around the PS4?

Its the same in reverse why would you expect the Xbox one in performance to match the PS4 performance if the game engine and Graphics Api was built around the GNMX & PS4 Hardware?

You wouldn't I would imagine.
The hardware has in both machines performance indexes.

The Graphics Api and wrapper level can show what your team with skill can do with the hardware at hand. Through Time & money , team size , game theory & design ,Experience with said hardware. Custom designs in software to take advantage of said hardware.
Many factors go into making games.

Again as an Example:

However, CEO Stewart Gilray spoke with Worlds Factory to clear up those statements, saying...
“Actually that is NOT what he said. I spoke to Lorne afterwards and what he meant when speaking to that guy was that budgets, schedules and perceivable differences would narrow, NOT that the Xbox One performance is improving to align with PS4, that is just physically impossible. The PS4 has MORE COMPUTE units, and faster memory and a whole bunch of things, that would make that physically impossible to happen.”

Now the key point is if you have the Hardware, that does not mean your performance can be taken advantage of unless your Tools, Middleware, game Engine, Api, game design & theory..developer team and size and experience with the hardware and tools line up!

The hardware can be as powerful as it can be, but unless the team designs the game theory, and have tools and middleware and experience and investment capital and time..it would not matter.

Its just that Simple.

Of course I get a disagreement.. LOL

Again the PS4 does not use OpenGL

The PS4 OS is a fork of FreeBSD 9
And use's

[The PlayStation 4 features two graphics APIs, a low level API named GNM and a high level API named GNMX. Most people start with the GNMX API which wraps around GNM and manages the more esoteric GPU details in a way that's a lot more familiar if users are used to platforms like Direct3D 11.]

Has its own shader language

[Another key area of the game is its programmable pixel shaders. Sony's own PlayStation Shader Language (PSSL) was introduced on the PlayStation 4.]

Now you guys are starting to get it. Xbox one and Windows Tian is one platform therefore minimum work is needed to port games to and from them PS for is the outlier, so what you end up with is this situation where more time is spent on getting the PS for up and running than running the cold on Xbox one or PC that's the essence of why Microsoft went with DX 12 model. And I have to be a little bit of a ass but what PC do you know has its main RAM as GDDR5 so that should have told you they were never the same.

Never played it on PC but it looks decent. Tell you what though, the folks over at Polyphony could be doing with playing it to learn something about engine noises! Big thumbs up for sound.

These 2 partial quotes,

“But yes it was difficult. PS4 required a total rewrite of the graphics engine because the way you need to work on the console is totally different,"

and,

“The Xbox One is much more similar to the PC because you can take advantage of the fact that they share more technologies...”

from Stefano Casillo read very familiar. Where have I read something similar to this before?... Ahhh yes, right here: http://www.engadget.com/200...

Shaun Himmerick (executive producer for Wheelman) was quoted as saying of the PS3 and XB360,

"The politically incorrect answer is that the PS3 is a huge pain in the ass. Anyone making a game, if you're going to make it for both, just lead on the PS3 because if it works on the PS3, it'll work on 360."

"We had to play catch up on the PS3 because of the memory constraints and how it renders -- how it processes is just different. And it's harder on the PS3," Himmerick continued. "The Xbox is just like a dumb PC, which is great because it's easier to build a game on a PC."

I suspect there will be more complaints like Casillo’s coming from other devs in the future, as they are forced to reckon with the PS4’s true nature.
