What I am reading from this is...

Mantle is, by an large, extremely similar to the APIs used in next-gen consoles, as first suspected by Anand and others. Microsoft and AMD, however, denied this later on, most probably because of political reasons, and possibly to their credit, due to custom copyrighted changes in each console; so technically the propriety APIs may not be exactly the same but VERY VERY similar nonetheless.

This is exactly why some developers are pushing for Mantle on PC. Because the difference between PS4 API is so miniscule that the associated costs (from switching PS4 API to Mantle) are tiny compared to the gains with Mantle over DirectX. If PS4 had an entirely different API, nobody would bother implementing Mantle, given AMD's market share, and financial hurdles.

Accurary.

PS4 = Optimized for PS4
AMD GPUs = Optimized for Mantle
Intel, Xbone, nVidia (Windows) = Generic DirectX
Intel, nVidia (Linux) = Generic OpenGL

They are focusing on PS4 and AMD GPUs in terms of performance and using the generic code for the others plataforms... that means Lead Plataform.

And more... any optimization made for Mantle willl improve PS4 too... Xbone not.

nice very very nice.

I cleary can't see saying enywhere about Xbone too but...

"PS4 & Mantle will DRIVE Frostbite design and optimisation going forward"

Drive = Lead plataform... the development for PS4 and Mantle will define how the Frostbite future optmizations.

You can try to spin now again

PS. I can mark the text in the slide if you want.

Is that you, misterxmedia?

(For those who never visited his blog: Notice the strange syntax and spelling errors, derogatory remark identical to essentially every entry in mxm's blog)

I hope in a few years the Playstation 4 isn't lumped in with the PC as a "lead platform".
Let the PC evolve farther ahead, don't hold back the games because of slow console hardware!

With that in mind, Frostbite doesn't really have a lead platform, it's a cross generation game engine that's incredibly scalable.
It's the games that will have a lead platform.
For example: Battlefield 4 was still very much using the PC as the lead platform, consoles had reduced resolutions and at most high settings vs the PC's Ultra.

Then again, Frostbite was essentially built and used exclusively by EA to save money, it's cheaper for EA to have all it's Studio's using the one game engine than having to license/pay for various versions of Unreal/Gamebryo/CryEngine etc'.

As for Mantle...
It's not limited to AMD's GPU's. It's also not limited to Graphics Core Next, it's an Open API, Mantle is also not on the consoles, it's similar to the consoles low-level API and the hardware is also PC hardware, which is what is going to make translating engines/games between the two platforms essentially a breeze.

No I'm not how about that put some news about ps4 keep crashing for early owner not doing damage control by posting other news to make ps4 looks good 

Btw I hope Sony gives u free ps4 because u do ur best to make ps4 looks good instead of paying around $1500 for ps3.5

Moderated,

$100 more for the Xbone 720 is nice too lol

1. Its cheaper than xbox,

2. Why should people only post bad news stories

3. the text is very clear in each image why PS4 is the lead platform, or did you only look at the pictures?
