Even if DirectX 12 improves performance to the Xbox One, will there be any risk of overheating like one of the quotes in the OP? If it's prone to overheating, I'm not sure it'll be worth it. The Xbox One is good as it is right now.

This was especific are of the code that was  badly coded... it won't increase any game overall performance... maybe free a little of the CPU so you can uso for a little better physics or AI in this determinate case only.

That is why the same guy said he needs to knows how, where and when it gives double performance.

"Good; always be suspicious of ANY perf. improvement claims. e.g. what *exactly* got 50-100% faster? Faster than what? Details!"

You are wrong.

DX12 is going to help improve crappy use of DX11.

If developer A made game using DX11 ver of XBO and it is good, you can count on less then 10% of performance improvement.

But developer B wasted all of XBO power by using it WRONG. Have no fear - some of common mistakes will be automaticly removed by DX12.

And That's How I See It.

Just like on android. Since android API 8 (or 9) all views are automaticly hardware accelerated. The same phone on android 2.3 is much faster then using android 2.1

It will improve the performance by 2x or close to 2x, I believe that. The thing is, why do you try to improve the hardware performance when you have the cloud at your disposal?

DX12 will be twice as fast as DX11 but the X1 does not use DX at all in most cases. The low level API that is being used by most developers already has the speed of DX12 right now.

Only tech demos written in DX will be faster but no actual games because they are allready written in a low level, mantle-like API.

There will be no speed improvement for X1 games, only the idie games and tech demos written in DX will benefit.

Every person with more than an once of brain would be skeptical about any claim without evidence.

About people complain that they are sony devs, look at the full op there are other devs even from ms. But those people just take good pr as gospel and bad pr, pieces, opinions and facts as the work of haters.

It should be obvious that advancements in API's will bring improvements in performance. However, saying the XOne will be getting 2x more power is very misleading. Real world improvements will be anywhere between 5-20% which is still significant!

Great way to insult people.

You used the first line to insult everyone being clueless  and then the rest of your posting is proving without any doubt that it is essentially you that doesn't have the slightest clue about the subject.

If it improves the end result, what else could really matter. I agree with others in that it will probably only help programs that are poorly written or it will help programs that are not even written yet to be better optimized out of the gate.

^ AMD & nVidia add game specific patches and workarounds in drivers. It's not exactly the same thing.

Of course drivers themselves can and do get better, and boost perf. Especially in CPU bound code, better drivers and new features can reduce CPU load significantly.

However if a game is already GPU throughput limited, then a driver change is less effective.

For example getting a game from 720p to 1080p uses 2X more GPU throughput, increasing load on shaders, texture units, memory bandwidth, and ROPs. Drivers can sometimes compile better shaders, but they can't increase the other resources.
