Intel created a SIGGRAPH 2014 demo to demonstrate the performance and power benefits of DirectX 12, compared to DirectX 11, on Intel HD4400 graphics. Let's look at their results.

This is fantastic! I knew tha DX12 woulda have a similar impact on gaming, but boy I'm happy to hear about it. It would make a huge improvment for me in the moment since I'm running on board graphics, but the thing I like the most is that DX12 is for everyone and just a proprietary nVidia or AMD thing and the best of all it is free! I can't wait for it coming.

If nvidia makes the gtx 570 compatible with dx12 i would be amazed of nvidia

They won't, just their current top end cards i.e 770, 780, 780 Ti, Titan etc...

*EDIT*

Nevermind spoke too soon, "Nearly" all 400, 500 and 600 series cards will be supported while all 700 series cards will get support but things might change.

It will just be a driver update. That is the only way older cards can get the support, though however as Dicehunter has said it is subject to change.
 
if its not coming to windows 7.. i will wait untill windows 9 to rejoice about an api improvement that we should have seen with dx 11.
as far as im concerened ms could have cranked this api out "or atleast the benifits of low level hardware access" any time they liked, and are only releasing it now due to the fact mantle had such good press.. but instead of releasing similar sooner they chose to do incrimental tedious and meaningless update which co-insoded with a new os release. and added "you can get this new direct x if you buy our new opperating system"
i know thats how they suckerd me in to getting vista. well fool me once shame on you fool me twice and im an idiot.. well im not an idiot so i will wait for windows 9.
 
We will see the real benefits if we can test them. (I mean DX12 and Manitle)
I hope the game developers will use them in the right way. :)
As I know Windows 8.1 will support DX12. Windows 7 will not have this option.
 
While DX12 is looking to be a good thing for everybody, it's still quite amazing how much extra performance they are able to gain over DX11. What's equally shocking is how much of a resource hog current DX and drivers have become.

Since I went twin GPU's (first 570's, now 680's) a while back, my old trusty 2500k @ 4.6ghz is usually the component that's pushed the most. In some games it's due to their more complex nature, rather than being a simplistic but pretty FPS for example. However, ALL games are upping their geometry count which means the CPU gets more of a hammering. I have several titles that'd be TRANSFORMED FPS-wise if CPU load were a little less.

We've already seen some good CPU-saving results with Mantle, albeit with a bespoke code path requirement. Additionally, I was pleasantly surprised when recent NV driver updates gave me quite a boost in certain titles that were largely CPU-bound.

Now, with NV, AMD and Intel working together with MS to massively improve the efficiency of DX, well things are looking good.

One thought though, if DX12 is likely to be compatible with NV 400+ series - well, the mid to high-end variants at least - as well as AMD (sorry, not sure which ones are supported) then aren't both AMD and NV potentially loosing sales? I mean, if my 680's get a new lease of life thanks to my CPU being able to feed them more efficiently, maybe I'll hold off on that 880 purchase I had in mind.

Still, you could equally argue that a higher-end GPU will benefit EVEN MORE from on older CPU (relatively speaking, the older CPU has less chance to be the limiting factor) so customers may well spend on a new GPU over a replacement CPU as the latter - thanks to DX12 - is now able to keep up with higher-end GPU hardware...this is largely what AMD's Mantle enabled, with users of lower-end CPU's still getting an upgrade benefit from a higher-end GPU that would previously have been CPU limited.

Interesting times indeed - I hope MS release a public rolling demo, like the asteroid one, so we can see first hand how OUR systems will benefit.

Yes but you have to remember MS announced they are discontinuing performance updates for Windows 7 as of this coming January which includes DX12 and DX12 launches at the end of 2015.

DX12 will only be for Windows 8 and newer.

Yes, I think you're correct, though I've read both arguments several times...I guess we shall see!

However, you could argue that MS may use this as a push to get people to upgrade from W7, equally however would they really ignore such a large % of the user base just on the off-chance these people will consider DX12 a must have?

DX12 seems, on the face of it, largely marketed towards gamers so how will they react? I mean, DX12 lets you push your older hardware that little bit further potentially, but an £80 (or whatever it is) cost for this when the user has to upgrade windows might put them off.

I guess we shall see. Though I'd hope, despite support for W7 ending soon (well, major updates etc.) the DX12 update is STILL going to be made available.

Currently on W7 myself, tried W8 but at the time it simply wasn't as fluid for gaming. I do have W8.1 ready to install (need a pair of SSD's to proceed) but reports from friends who've recently upgraded show it's not proving quite as stable as W7 currently.

Going to follow all things DX12 with interest, and will decide nearer the time.

I don't think MS really care if windows 7 users don't get DX12 and have to upgrade to window 8 or newer, The only real incentive for gamers buying a new OS is the performance upgrades anyway.

I think that's subjective about W8, WYP did a damn good gaming test between 7 and 8 and there is literally no difference between 7 & 8 for gaming, I have 7 & 8.1 dual booting and I honestly cannot tell them apart in games.

8.1 has better frame times and it does feel more fluid in certain games even if the FPS are the same but apart from that I can't tell them apart.

Once again I suspect you're right.

I did some back-to-back (dual boot) testing myself of W7 vs. W8 a while back - before 8.1 was available. I actually got quite used to W8, but performance was down in several games I played. Not tried 8.1 yet, but will do so at some point. Only reports from a friend who's recently upgraded about frequent blue-screens has put me off. He thought initially it was down to his gaming NIC, but the issue still occurs without it. Then again, he's always getting obscure issues lol.

I think I will still go 8.1 myself, but using a pair of SSD's vs. the single that W7 uses - that'll give it a slight head start in the performance stakes. I can always swap back to the older SSD.

Your final comment about 8.1 frame times is interesting. My W8 experience showed even the same FPS could mean a different experience. If 8.1 has addressed this, we assume frame time, issue then I'm more keen to give it a go. You may have just cost me the price of two SSD's.... ;)

You've totally lost me on the bit I highlighted ^_^

You mean you will be using 1 for W7 and another for W8.1 ? If so then W7 will not have the performance lead just because you have another SSD plugged in, W8.1 is faster without a shadow of a doubt, More snappy etc... :)

Lol. Well, I was going to keep W7 on my existing FAST single SSD, but put W8.1 on a pair of new SSD's that I'll stripe. Not overly concerned about doing a direct performance comparison via dual boost this time...just want to play lol.

My original plans were slightly nerfed when I realised my motherboard only has TWO Intel SATA rev 3 ports, four Intel SATA rev 2 ports and the additional two "fast" SATA rev 3 connections are actually crappy (to put it mildly) Marvell controllers. These are not in themselves an issue, but when BOTH ports are only given a single PCI-E 2.0 lane...well, they suck. So, the PC will have 2x SSD's on SATA rev 3 for OS (8.1) and some games and a spinner on a SATA rev 2 port for data.

TL DR - I'm having a play :)
