If you honestly believe DX12 were made in conjunction with the XBO I feel sorry for your brain.

Hahahaha, you guys are the best, seriously!

There is something truly magnificent about a well organized functional Piece of software. You look through the code and think, How the hell did they think to implement this.

Its the kinda thing where you're like I want to add this feature and the software just says ok because it just works, no bugs or random errors in the structure of the system to stand in your way.

Its almost elemental, everything works because everything was built correctly or has been tailored to bits. Similar to how atoms/subatomic particles make up the universe, Everything just works, the universe doesn't crash every now and then because its component parts are all functioning properly.

A good piece of software, like that Is something to see. GL doesn't appear to be there yet.

An example of what I am talking about would be a good physics engine all of its components parts just whizzing away behind the scenes, throwing masses around inertias, vectors, all manner Variables each with its own purpose, in an elegant invisible dance on a piece of silicon. Programs are like amazing pieces of machinery both in complexity and capability.

Excuse me just nerding out. :D

Im also not sure what exactly im trying to say. I hope gl gets a rewrite so it gets that luster and functionality. I always saw gl as the underdog this is one of the first times I've heard someone so experienced with it talk about it.

Pretty much every dev have their "developing expertise and tools" ... i really trust in ICE Team because is the only team that don't talk ... just to talk...
the results of OpenGL it's clear "for real developers" but for developers don't have real deep expertise directx is good because..

OpenGL is for Professional
Directx is for Kids... good kids yes... but only kids.

BTW this is my opinion "and i have 21 years of development in 21 team"

Edit: just feel like deleting my post, not sure why I want to respond to George anymore. Sorry for taking up space.

Where on earth did you come up with that pile of bull$hit? There is a reason why developers PAY to use DirectX even though they can use OpenGL for free. And there is a reason why AMD has to PAY developers to add Mantle support to their games... because there is no way they'd spend an additional month or two adding mantle support which can only be used on 0.04% of gaming PC's.

And yes... that number is correct. R9-2xx series cards are only 0.04% of the graphics cards in the hands of consumers. http://store.steampowered.c...

The only instances where Mantle even gives a decent performance boost is when you have a crappy CPU that can't keep up with the GPU, and considering the price of AMD processors... not many people out there who are buying R9-2xx series cards have a crappy AMD CPU since they're dirt cheap. And even less people who would spend that kind of cash on a graphics card are going to be running it with an AMD APU.

You want to see how much worse OpenGL performs than DirectX? Go run the "heaven" benchmark and switch between both API's in real time in the settings. Not only does the image quality drop when using OpenGL, there's also a sizable performance hit.

@Andrew I mostly agree with you, except about Mantle (lack of) benefits. I have an i7-3820 and crossfire R9-290s, and in BF4 I gain literally 60-70 frames per second using Mantle over Dx11.

I usually stick to DirectX 11 though, because those extra frames add a whole lot of heat to the GPUs!

This was always the case for consoles so i don't understand this dx12 hyping everything is custom for consoles

Sorry rainslacker, I totally disagree. DX12 has been put together for all microsoft tech and that includes Surface, Phone, PC and xbox one. The stream and efficiency of information will be superior to what is current being used on current programming. As for xbox one..well if you want to believe that DX12 will not better the consoles current form then fool on you!

@baba

I never stated that DX12 wouldn't improve efficiency on the XB1. I merely stated that this dev is talking about PC implementations and not consoles.

What it comes down to is that the major improvement in DX12 is the close to metal access for devices and PC GPU's. This programming technique has been used on consoles since the Atari 2600, and is nothing new. It's why consoles can produce good graphics with lower powered GPU's compared to their PC counterparts.

The rendering pipeline is improved in DX12 going by what this developer says. So yes, that will speed up performance. Larger batch processing will also improve it.

However, the person I was replying to said

"What's even more interesting is that games developed using Directx 12's feature set will perform greatly on Xbox One and likely better than the competition"

To which I disagree. The dev in the article specifically mentions VOGL, which the PS doesn't use. It has it's own rendering pipeline which is aggressive, and offers larger batch processing than the standard OGL. Sony designed it that way to get more performance out of it. It also supports extensions, which means that devs can improve on it where they see the need.

The dev in the article never said any such thing, but merely stated the differences on the development end, which would allow DX12 to become better than OGL if OGL stays stagnant.

His statement is complete fan boy fodder and isn't based on any real merit other than he wants it to be true.

The thing about OpenGL is that it's open. That means that developers can change it. OpenGL grows every year. It gets better every year. And currently, there is nothing that says that DX12 is really better than OGL. One may do some things better than the other, but lifeisgames doesn't understand how either of these API's work,or what it means for the actual developer when making games.
