Intel showed off a DirectX 12 demo at SIGGRAPH 2014 that I think most of you will find interesting. Intel plans on releasing the demo publicly once Microsoft releases DirectX 12.

In the demo we render a scene of 50,000 fully dynamic and unique asteroids in one of two modes: maximum performance and maximum power saving. The application can switch between using the DirectX 11 and DirectX 12 APIs at the tap of a button. We are showing the demo in our SIGGRAPH booth running live on a Microsoft Surface Pro 3 tablet with an Intel® 4th Generation Core™ processor.

Not to sounds like a spoiled jerk, but I'd rather see it on a high end system with the best video card. Surface is great and all, but it should get the trickle down scraps. I want to see the best that it can do. The absolute best.

I'm sure it's impressive on a Surface. But, I'm guessing what's great on the Surface is mediocre on a high end machine.
 
But if it's totally fucking awesome on the Surface, you'll shit your pants when it runs on a high end machine. I guess that's the point.
 
I find that near 74% increase in performance just by moving to DX12 a little hard to believe. Sure it drew more power, but what exactly is it doing? I guess I'll have to read up on DX12.

Well at this point all we can do is speculate, but if you make a comparison to Mantle, high end systems might not get that big of a boost. I hope that DX12 does gives high end systems a big boost, but they've got to show me the numbers for me to get excited. :)

That may be true, but higher performing hardware wouldn't need the same amount of boosting at any rate.
 
My guess is they concentrate on the bulk of users (low to mid) and the scraps go to the high end users. Also I would bet they found the best case scenario to demo.

As this is something that the Xbox One needs, my bet is it is highly oriented to to it's hardware low to mid than anything else.

I hope I am wrong and the benefits are spread across the spectrum.

Does anyone think DX12 is going to be released with Win9?

And what's where the performance gains are most needed, so it's really a smart business move.

Maybe with, but not only for. Unless MS really wants to blow itself.
 
MS said many times that DX12 will not need a new OS or new hardware, any hardware capable of DX11 will be able to run DX12, I think windows 8.1 its what will be needed as maximum requirement for fully implement of DX12, same as DX11.2..

Maybe Intel decided to make a non-idiotic driver for a change?
 
Its is great news for all battery powered devices. With the new Intel (up to 30% power saving) chip and directx 12 (up to 50% power saving) we could be looking at a power saving of up to 80% when gaming.

All tablets and phones will see a marked improvement.
 
I remember reading that 8.1 wont get any new feature upgrades after the next big patch. Most likely it will be windows 9 only.
 
Considering DX12 isn't supposed to do anything really "amazing" in the software and is backwards compatible with current HW. I imagine the magic is reworking the stack to actually remove a lot of fluff.
 
I'd like to know when it was that everyone just started believing every word the sales crew pitched?

Last time i checked... "Wow this game i just bought really lived up to the exact impression and specs/performance that the marketing material/media spun all these months leading up till release" ... said no one ever.
 
so on the surface pro 3 the CPU/GPU are on the same die.

I started to think about Microsoft saying things about xbox one benefits with DX12 and it now makes sense, because it's an APU.

I don't think that the high end PC users will see too much of an effect though.
 
Better CPU utilization would naturally help lower end GPUs, where often the CPU paired with them is holding them back. I know it sounds counter-intuitive, but that is how it has resulted with Mantle. You would think the opposite would be true. This shows DX12's similarities with Mantle.

MS also has a history of restricting DX to certain versions of Windows in order to get users to upgrade. I don't see this changing, I'd be surprised if DX12 was released as a standalone download for Windows7/8 users. I mean it has already limited DX11.2 to Windows 8.1, not even 8 gets it.
 
Well, I hope Windows 7 gets it because there's no way in hell I'm putting 8 back on one of my PCs after paying the Catholic church for those exorcisms.....:D

Do you know if there will dx 12 features that require new silicon? An example from the past being bump mapping (old I know).

I am liking the idea that anything dx 11 compatible can do dx 12, I just wonder if there are specific features that may not be avail.

I am looking to upgrade my GPU, the upcoming gtx 880 (if rumors are true) might be my new card.

Of course, we all know how long it takes games to incorporate new dx versions much less features.
 
Multi-threading better sounds awesome in a big way from my perspective.

I'm wondering if something (besides windows in a kind-a sort-a way) will use all 8 of my cores which would be awesome.

Playing ESO all settings at max, 5760*1080 occasionally gets my GPU to 99%, this is w/o going to the PVP areas which are much more demanding from what I have read.

I think it's safe to say that there will be a 0% chance Windows 7 will get DX12. Given MS's own history of this, plus the massive number of people they want to see upgrade off of 7. Not porting DX12 to Win7 is a financial no brainer.

it'd be a 65% improvement not 80%. learn to maths bro

So will the 800GTX series be DX12 then?

Nvidia already said all their DX11 card will support DX12, so cards even back to 600 series.

So do you think Mantle does something amazing?
 
Maybe this'll push Mario Kart into 1080p. Assuming Wii u uses DX 11. I believe the Wii U uses a GPUPU if that is even relevant to this post.

Why would I think mantle diss anything amazing? Mantle I'd it's own stack interacting with the GCN architecture.

Unless you thought Glide was "amazing" then I guess mantle would be too, they are similar.
