DirectX 12 GDC 2014 presentation: Low-Level Access, DX11 GPUs, Holiday 2015

because the CPU hardware on the xbone is identical to the PS4, so differences between software running on both can be attributed to the development environment (which can be improved over time) and a weaker GPU (which obviously can't)

a new graphics API that reduces CPU overhead is great but it won't replace the lost compute units, ROPs, and memory bandwidth that was cut from the xbone to make room for that awkward cache

Ahhh ok I see what your are saying now. Yeah, I agree. The performance on the X1 will probably increase but nothing compared to what the ps4 can currently output.
 
A new throttle pedal doesn't give the engine more horse power. Mantle was overhyped a bit as well.

But as I said, reducing the CPU footprint and parallelizing the runtime is certainly a valuable thing especially given the XBO's CPU. I would be surprised though if the XBO doesn't already have many of those improvements. For instance, they already spoke about improved low-level support when they announced the XBO's "mono" driver.

I'm intrigued, they sold us mono driver as low-level api months ago.
 
Lol, that shit takes goddamn forever. I'd have expected DX15 by then.

Do you even know what you are talking about or are you just interested in undermining everything MS does all of the time?

This is aimed at developers who also need time to implement everything, so obviously the games announced at E3 for 2015 will use it.
 
so....Penello saying Microsoft created DX and all that shit sort of redeemed?
Not to say they'll get better performance than PS4 still, but it helps alleviate the gap?

On the PC side I'm hella hyped though, this is fantastic!
Pretty happy I maintained some hope MS would do something about DX :D
May this be the beginning of a new, better era, for all, and we shall prosper in increased efficiency for all!
Not at all IMO....the key to all these slides is where they CONTINUALLY keep saying "console like." I'm not really sure why people continue to miss this...like all the "will PS4/Xbone use Mantle?" Stuff....

Consoles don't NEED these things because their APIs are already as low level as it gets...it's the PC where DX12/Mantle will have by far the most benefit....

I'm sure the Xbone will benefit because it's existing tools suck...but let's not get carried away
 
Ryan Shrout: Windows 7 support? Won't be announcing anything today but they understand the request.

Which translates to "Yeah, we hear you yelling but it's going to be Win8/9 suckers".
 
dGPU made by nvidia that's why they were showing Forza 5 running on Nvidia hardware. the situation is complicated, MS doesn't want to give too much away for sony to rebound. keep digging all will be revealed in 2015.

Also, Amazon, Apple, Samsung, Walmart, Tesco and Heinz Tomato Ketchup will enter the console market eventually. Never show your hand too early, ya know.
 
I thought that CPU overhead doesn't exist on consoles anyway? Low level access, coding to the metal etc.

Automatically spreading the work across CPU cores instead of having a dependency on a main single thread is a big deal - especially as individual cores aren't getting faster, but systems are gaining more cores.
 
I think if there was any real performance boost to the XBOne, they wouldn't have skirted over it quite that quickly...

The console already has low level access to the GPU and low overhead, the main features of DX12. MS themselves said so last year when they released their "mono" driver.

Marc Whitten said:
Since E3, an example is that we’ve dropped in what we internally call our mono driver. It’s our graphics driver that really is 100 percent optimised for the Xbox One hardware. You start with the base [DirectX] driver, and then you take out all parts that don’t look like Xbox One and you add in everything that really optimises that experience. Almost all of our content partners have really picked it up now, and I think it’s made a really nice improvement.

There will be some improvements of course but I guess they will be rather minor.

I am guessing Windows 8.1/9 support for Direct X12.
If you haven't upgraded yet, now is the time...


Eh...?

What's the reason to upgrade now if they actually announced nothing happens until 2016?

It's the opposite message: time to NOT upgrade and wait another couple of years.
 
The good news in holiday 2015, most people should be in Win +8, so no need to support Win7. Just don't fuck it up MS, and make DX12 exclusive to Win9.
 
Who else can't believe it's not going to out until 2015 for the consumer version. Jeez. I'm not getting any younger.

Games already benefit from 8.1, see Battlefield 4, and more games are coming this fall...

Aye, I agree. I'd forgotten about the mono-drivers as well. It seems that the the major drivers are already in place and only the multi-core threading is going to be improved. I can't see how that's going to help with the esRam though... :/

That sounds interesting indeed. Can we guess how much of a performance boost this can possibly bring to the table?
