DirectX 12 - ExecuteIndirect Command Further Improves Performance & Greatly Reduces CPU Usage

At GDC 2015, Microsoft revealed a new, complete indirect dispatching draw solution that can be used by all DX12 hardware from Feature Level 11 and up. This new draw solution replaces DX11’s DrawIndirect and DispatchIndirect, and brings major performance improvements to the already incredible performance that DX12 can achieve.

I believe DX12 will be something good for the Xbone, but it's way too overhype by the fans like it's going to be bigger than itself

hello123390d ago (Edited 3390d ago )

Angry Playstation fans will tell you dx12 will not benefit xb1?

OK whatever dx12 is a Microsoft API and x box 1 is an Microsoft product. Do you truly think they developed the API only for PC hardware? Its not a logical argument at all.

It its well known coding for multiple CPU cores is difficult using the dx9- dx11 API

Devs having been facing the same exact issues when developing a game for console and PC for years. Console is not easier thats a false belief. I bet if we could run console tests now we will see most of the work is been achieved on one core and the rest of the cores are uneven.

Akametal@ It uses all cores but the work on the cores is uneven its an issue with API that why we are seeing huge differences in frame rate from dx11 to dx12.

You don't understand it misterx is what you use to dismiss things you don't understand.

akaFullMetal3390d ago

Only using one core?!?!?!? Man you are still spewing illogical guesses and MisterXMedia propaganda.

Google is your friend:


"with DirectX11,I can talk to exactly 1 of them at a time."

MrSec843390d ago

DX12 by itself won't do anything, but if developers write their games for DX12, then of course improvements will be had.

Improvements in performance are a standard thing of every console generation, if people disagree then they only need to look at the difference between Halo 3 and Halo 4, along with the games in between.
But Halo 3 was a 640p game, that had frame drops and the graphics while good at the time were nothing compared to Halo 4, Halo 4 was a native 720p game, with a locked frame rate, which ran better than Halo 3 and it also had far more details, effects and generally curb stomped Halo 3 for graphics.

The same thing will happen all round this generation, DX12 is one part of a bigger array of things that will gradually be improved as the generation goes on.

GutZ313390d ago

I say let the hype train do its thing. We are sure to learn of its success or derailment in the coming months.

MasterCornholio3390d ago (Edited 3390d ago )

Yep that's probably the best thing to do.

Allow Direct X 12 to come out first and let Eurogamer give us the verdict on it.

But if there's one thing that I can guarantee is that Mr.X is a fraud and nobody should use his blog as a source of information.

Fireseed3390d ago

Kinda hard for this to not be overhyped because DX 12 is to PC gaming what the 8th gen consoles are to console gaming.

DirectX 12 is a significant shift towards turning gaming PCs into low-cost multimedia devices?

DirectX 12 is a significant shift towards turning gaming PCs into low-cost multimedia devices?

Do you mean its a Bad thing, or a good thing?

Its a very good thing because time after time its been already proven that having the convenience to access your devices anywhere and everywhere is good for both business and users.

Remember, gaming started in the arcades, and now look at it, its in the convenience of your home. "Conveniency" is what driving this trend, and will continue to grow in the coming years.

Bigpappy3390d ago

The proof will be in the pudding. As developers start using it like Mr. Wardell has, we will see more evidence of what DX12's impact will be. I have read some comments from developers hyping DX12 more than Xbox or PC fans.

I am reading so great things, and even seeing some real-time videos of early usage. But something inside is asking for more. Maybe I need to play s 15 minute demo of a real game , even in beta.

But don't take this to mean I am not excited or don't believe the hype. That would be the WRONG conclusion. I just hunger for more direct interaction and don't want the long wait.

traumadisaster3390d ago (Edited 3390d ago )

It just simply didn't need to be announced until the first game was released.

Then during interviews the developer could be asked about details and he could explain dx12.

That would get media then inquiring with MS, then it could be explained properly.

Bigpappy3390d ago (Edited 3390d ago )

I agree that the hype is to high with not much to show. But, there was no way M$ could control the hype. ADM was already pushing Mantle, IBM and NVIDIA are very excited about it and have been hyping it more than M$.

Then we have wardell super excited about the results he is seeing while developing his new engine on DX12. If he has already created an engine, then you know other small developers also spread have it.

It's supported by all the major engines already.

M$'s push has really been to developers, mostly the smaller one. I am sure some of the big ones are on board, but others may be avoiding the API because it may complicated porting to other API for non Windows systems.

This is why Phil keeps saying: It depends on if the games are made to support the features of the API.

Off topic: Why are PS fans so fixated with Mr.X? I only heard of him cause they keep referencing him in DX12 article. I am yet to read any of the people they accuse of following him ever mention him. They are making him popular and he can capitalize on this if he is smart. Can turn that fame into millions of dollars.

Maximum PC has an interview with a game demo running DX12. It seems to be running on a Kaveri APU with a R290. One of the guys showing the demo says that it is GPU bound. That is a ton of GPU to be bound by chip like a Kaveri. That alone should give you an idea of how much DX12 boost a APU. Also see the Viking village demo on Intel integrated graphics which are considered weak compared to AMD graphics on their APUs. Even one of the Microsoft presenters admitted they have downplayed information in one instance to keep expectations in check. It's beginning to look like their ideas are working.

OUROSMAG3390d ago

It would be a mistake to think that DX12 will give zero improvements to the XB1. It is just as silly to believe that the PS4 won't receive a similar update to its software.

Pixelart3389d ago

There's nothing in it for the PS4 since it doesn't use Direct X - a MS creation.

OUROSMAG3389d ago

I didn't mean Direct X.

Pretty cool. Should help devs adopt more modern rendering techniques on both PC & Xbox rather than have to target old versions to cover the majority of their users.

I saw a report that the new Windows update causes a performance decrease in gaming performance.

Here comes another feature update that resets my settings.

Profchaos1480d ago

If it doesn't delete your files ala 1809 consider it a minor victory

1nsomniac1480d ago

I’ve noticed they do this as well.

I wonder how they legally get away with stealthily resetting all the privacy settings to allow tracking and monitoring without notifying you. It was only by chance I noticed it last time.

Unspoken1480d ago

Any software you use does this unfortunately.

1nsomniac1480d ago (Edited 1480d ago )

I think you’re misunderstanding what happens. All your windows settings remain untouched, it doesn’t change any of your settings accept Those related to your privacy. So all those privacy settings you agreed not to share during the installation and other privacy terms that you agreed not to share, within the privacy options page, even your offline linked windows accounts. It secretly enables all of those options without notifying you that it’s changed your selected options that both parties had agreed to. I don’t think they’ll be allowed to continue to do that under GDPR laws so we’ll see if it happens again. However unfortunately for me being in the UK, we won’t have GDPR laws for much longer after we leave the EU.

The term "willingly" is questionable at best...
