Project Cars Dev: DX12 can boost Xbox One version 30-40%

That's a long time and a huge number of computers that could be not paying for an upgrade. Maybe the cost of support in a fractured user base that refuses to upgrade is worth the loss of income from offering the upgrade free. I don't have any idea of the numbers. It just seems odd. Then there's the "support for the life of the device" part that's kind of vague. Does changing the CPU, mainboard and RAM of a computer mean you're extending the life of the device, or ending it?

bro its just a hunch im pretty good at spotting paid deals and paid reviews an shiz my brain is just like one of those really big ones that can see through all teh agendas of microsoft and ea

@ProtossX: If it makes Sony heads feel any better:

"PS4 is pretty good already but there is much more to come.

Let's roll a hypothetical. Say Sony were to emulate in some way the main benefits of DX12 on their machine. Well, we'd see a good improvement as our engine loves it."

What do you mean? Why is DX12 compatibility necessary? Will the Windows 10 requirements be different from the preview requirements and require it? What changes with the OEM license?

im not gettin windows 10 true pc gamers don't even need windows 10

windows 7 is good enough an dx 11 is good enough

windows 10 is metro its lame, its bulky an laggy

im done with upgrading unless a true upgrade occurs

You don't own a gaming pc and you're not a PC gamer

You don't own an Xbox One

You don't own a PlayStation 4

You are a fakeboy, you are cancer.

all you need is windows 7 pc and a ps4

wiiU and xbone hasn't earned its keep and windows 10 is bloated metro

maybe grab some android phone or tablet

microsoft is literally dying in a corner right now with nintendo

DX12 is necessary when XBO switches it's programming model to DX12

EA DICE already stated they wanted DirectX12 API model to be the standard for 2016.

First problem, Intel Ivybridge with HD 4000 IGP laptops + Windows 10 DX11 can run DX11 based apps. The complexity starts with DX12 enabled GPU co-processor with DX11 IGP main display in laptops.

It's highly likely that my Intel Ivybridge with HD 4000 IGP with Radeon HD 8870M(or NVIDIA Fermi or Kepler GPU for that matter) laptop is dead for DirectX12 i.e. this is due to Intel's lack of DX12 drivers for HD 4000 IGP.

The driver model is different between DX11 and DX12.

Intel HD 4000 IGP has DX11 like NVIDIA Fermi or Kepler, but Intel refuses to update HD 4000 IGP for DX12.

Both HD 2500 IGP and HD 4000 IGP are Intel Ivybridge era IGP.

During Intel's pre-Haswell based PCs, the majority of PCs are laptops with Intel Ivybridge IGP and they being left out of DirectX12.

Second problem, Intel Atom Z3xxx SoC series has DX11 and Intel refuses to update these SoCs with DirectX12. Hence, Dell's Venue 8 Pro (and similar Intel Atom Z3xxx based tablets) with Intel Atom Z3xxx being sold on their Web store is already dead end.

To support DirectX12 Feature 11_0 (for DX11.0 GPUs), these GPU needs driver model updates.

Since Windows 10 fixes it's multi-threading CPU issues, it's highly I'll be switching to AMD APU thin laptops (I'm not into laptop bricks with fat GPUs). Most new laptops comes with Windows OEM licences.

When XBO switches to DX12 programming model, DX11 based PCs without DX12 driver model update will be dead. The winner during Intel Ivybridge era laptops will be AMD APU laptops with GCN IGP.

Only existing Intel Haswell IGP and PC with discrete DX12 enabled GPU (wihout Intel IGP main display) can leverage DirectX12 programming model and thier related applications.

As you can see, free Windows 10 is nearly nothing when your hardware is stuck on DX11 and it's related driver model.

My desktop PCs are not affected with this issue.

thats not true at all

cell was better than 360s cpu

but the 360s gpuwas better than the ps3s gpu

in the case of this gen ps4 basically beats or ties xbone in every category (i am not counting overclocking the cpu since that can easily be done on the ps4)

Helps or not, I can't wait for DX12 to hit the X1 bc I want to know who is right.

You hear arguments for both "it will barely help" and " it's going to make the X1 become a super computer".

I wanna be told the end!!!!!!

Lems just wait till DX13 is out and X1 will gain 300% powahhh, and this without taking Cloud into consideration !!

4k gaming at 60-80fps will be a piece of cake for X1...

I'm just kidding :P

Your quoting a consumer quote. I'd prefer to quote the actual developer

With Directx 12 round the corner, could this be upgraded with that in mind? Would it make any difference? - Question from consumer

Oh yes Our engine loves it also. - Developer

Sweet! So potentially whenever Microsoft ever get round to releasing it for the Xbox, Project Cars will be able to utilise it? - Follow up question

With DX12 the Xbox will perform extremely well for us. With the upcoming imminent patches it's already much better. - Developer response

We'll need to do some work of course but the way our engine is structured lends itself to the main benefits of DX12. - developer response

Then some more discussion, then another question.

Can we then expect a major update for project cars, whenever microsoft unleashes dx12 on xbox one? pretty please ;-) - Consumer Question

If we get it on time, yes. - Developer Response

..i presume with the architecture of xbox one games installing to hdd now, you can change pretty much any element of the game post release?

I know with disk based games you would have to 'patch around' elements in a game following release - Does this mean that future DX12 support is going to happen for certain? Or will budget dictate? - follow up question

There's always a bit of budget to take into account but we want to be at the forefront technically so I'll be allocating that budget as soon as we get access. - Developer Response

Then a couple more posts, but nothing said about PC.

Ian - as you have been quite open about DX12, what would be the benefits for project cars utilising DX12?- Consumer question (most likely follow up to above)

About 30-40% - Developer response

This all on an Xbox One Forum.

Who you going to believe a consumer who could be any body or the developer. Honestly.

Now I'd be supper impressed if it gets to 30% but didn't our resident idiot claim there would be no improvements.

@Antwan3K: He needs to be more specific in terms of what exactly gets 40% increase with DX12. This is way too ambiguous.

People really need to do some google-ing at least if they post links.

People would never know that PS4 is only using 6 cores.

I can't remember. Did the Xbox One resort to it's 7th core since the beginning or recently with relieving the Kinect loads on APU.

look at ron...in this thread.... he's giving answers to people that might not even know what it means to benchmark something.

Anyway this thread. It's way too ambiguous even if it's meant for the Xbox One.

What exactly gets a 40% increase ?

The graphics? The Framerate ? The resolution ?

I doubt it's even one of these. Perhaps it's something even something categorised under say "graphics". Like better parallax mapping or something.

@Gue1 said:

jokes on lems, it's only for PC.

The Xbox One 11.x API already features a number of tailored DX12 improvements.

DX12 doesn't 'add' power, it improves efficiency and the working environment. On Xbox One API improvements have been ongoing, on PC not so much, hence PC will see larger improvements.

-

Thread backfired lol.

That post is from a basic forum member, the developer says otherwise

Post Backfire :)

MS makes a lot of money off their OS, hardly nothing. What does DX12 have to do with it? Is Windows 10 going to be incompatible with all earlier versions and programs? Why would not being able to run the latest DX12 only games make tablets and laptops with Intel GPU's useless? They would still run the games they did before. What does Xbox have to do with PC? Neither Xbox nor one studio in EA control the industry. Just because they want everyone to use DX12, that doesn't mean everyone will.

Cows am scared. Thier Kyrptonite is hanging over their heads..............they are powerless around it.

That's funny, a lot of the PC gamers are saying 'all you need is a WII U and a PC'. PC already gets most of the games the PS4 and X1 get.

As shit as Windows 8 was, Windows 8.1 is amazing. Windows 10 will just be better. PC gamers who choose to be stubborn, sulk and stay with their old Windows, will only be hurting themselves. The end product of Windows 10 will perform better with games, especially with DX12, the api developers have been waiting years for.

I don't know about being a fakeboy, but you do talk some nonsense sometimes.

More than likely it'll be more gain than the PS fans are hoping for and less gain than the Xbox fans are hoping for.

The 40% gain is for PC no xbox one he was ask about xbox one and he fled,and in the page before it he stated that gains of DX12 also apply to the PS4 so if the difference was 5 vs 3 now it will be 7 vs 5 because the same performance gains also apply to the PS4.

I say this long time ago and you people didn't want to believe me the PS4 and xbox one have the same GPU and CPU family there is no Cell vs Xenon this gen,they are the same one is just stronger any software performance gain the xbox one can get the PS4 can get it to,and the other way around mostly.

No it was unlock on the last holiday SDK update but already games like Project cars use it,so is 7 cores on xbox one on Project cars vs the PS4 6 cores.

The 40% gain is for PC and people believe that it is for xbox one,this is the same thing that happen with Fable a few months ago.

The developer doesn't say xbox one he say DX12 and when he was ask about the xbox one he banish,so the post didn't backfire.

@tormentos: Give it a rest, he was talking about the benefits regarding the XB1 version of the game. Why waste so much energy trying to prove its not the case?

The little guy tries so hard doesn't he. It must take an enormous amount of energy to hate on a system as much as he does. It's rather pathetic if you ask me but it looks like his mom doesn't mind as long as he doesn't it from the confines of the basement.

@asylumni

>MS makes a lot of money off their OS, hardly nothing. What does DX12 have to do with it?

It's another DX9 to DX10 type shift, but without the cost of Windows 10 and with laptop's market share being larger than in year 2005.

>Is Windows 10 going to be incompatible with all earlier versions and programs?

Only minor issues for user side programs and games are user side programs. Drivers are also programs but for supervisor/kernel side.

User vs supervisor divide was from Unix type OS model requirement for CPU's feature set.

If one looks at 68K or PowerPC docs, they talk about user and supervisor instruction modes. X86 CPU has multiple levels i.e. the Ring # modes.

>Why would not being able to run the latest DX12 only games make tablets and laptops with Intel GPU's useless?

It depends on Intel GPU i.e. Intel Ivybridge GPU stays at DX11/WDM 1.3 while Intel Haswell GPU updates to DX12/WDM 2.0.

Laptops with AMD Enduro and NVIDIA Optimus will be unable to completely disable Intel GPU and switch to DX12 enabled AMD or NVIDIA GPU.

Laptops with AMD Enduro and NVIDIA Optimus keeps Intel GPU active with heavy computation being piped from AMD or NVIDIA GPU i.e. AMD or NVIDIA GPU is being use as a co-processor for Intel GPU.

The issue is the mixing of WDM 1.3(Win8.1's DX11) against WDM 2.0(Win10's DX12) driver models.

This problem is an issue with Intel Ivybridge's GPU.

>They would still run the games they did before. What does Xbox have to do with PC?

XBox 360 influenced the feature set for PC i.e. ultimately rendered DX9c Radaeon X1900 useless. Radeon HD 2900 or Geforce 8 was required for Xbox 360 era games.

>Neither Xbox nor one studio in EA control the industry. Just because they want everyone to use DX12, that doesn't mean everyone will.

In terms of features, Xbox 360 rendered ATI Radeon 1950 GPUs useless. I have the history to back my arguments. I switched to Geforce 8600M GT during this transition phase and dumped my Radeon X1600.

Minus the hardware failure, Geforce 8600M GT would be able to run Xbox 360 era games at comparable settings.

@tormentos:

The question AND topic are for frame rate issues for XBO and DX12 improvements.

PC (with AMD GPU)'s improvements are more than 40 percent i.e. just switching to Windows 10 gains about 40 percent fps increase while STILL running DX11.

AMD haven't released a driver specific for PCARS.

Spot on. Totally ignores the fact is an Xbox One forum.

Totally ignores the fact he said there would be no improvement, yet another developer claims there will be.

Pathetic

To all lemmings, when you have a system with a HD7770 you are not allowed to talk about performance related staff...

Hey Lemmingvalencia did you read that like i say it was for PC and what will improve with DX12 on xbox one 7 freaking %... Hahahaaaaaaaaaaaa

Man 7% what is that 2 frames.? because the game is not 60,so is not 7% of 60 frames but even if it was what would that be.?

Look how he say is on PC where the lack of Multithreading ability hurt them most not on xbox one,so i have been right all fu**ing long...hahahaha

OWNED all of you... damn i feel great...hahahaaaaaaaaaaaaa

Not sure why you quoted me moron. I said nothing about DX12. My post was directed at your unhealthy hate for a piece of plastic. You're a basement dwelling loser El Tormented.

Because you were talking shit about me trying to hard,in reality it wasn't i say it several times it was for PC but since i am always wrong right.? I was also in that right.? Hahahaa

Considering you do nothing here but defend the xbox and flame the PS4 i would go there lemming now enjoy the ownage..lol

No dumbass, you're trying to hard to hate on a piece of plastic. I don't care about DX12 or anything you say about performance/graphics. I just see post after post of your complete and utter hate. You have deep rooted issues El Tormented. Seek help

Nope, I flame dumbass fanboys like yourself, not the PS4. BIIIIGGGGGGG difference loser

Thats cool. A 7-10% enhancement is still nice for a mere conversion from DX11.

lol he's just trying too hard prove his flawed argument.... that DX12 wont do anything for X1 which is still wrong.

Pc version got the shaft, its not using DX11 MT, while the X1 is. Fact that with the next patch for the X1 will add 5-7% and then on top of that DX12 will add another "7% or more" on top of that. The guy isnt sure how much of an increase they will see.... but even a 10% increase from a 45 fps dip would allow the X1 to get nearly 50 fps instead of 45.

DX12 will clearly help the X1 in career mode in Project Cars, where handing lots a of AI and or weather gives the biggest dips. and this is a porting job coming from DX11 MT, not the ground up DX12 base which would have added more performance.

It all sounds awesome, Im just holding on for what Forza 6 has in store.

turns out the big boost was for PC after all LOL

NO you are a big time lemming who hates the PS4 and can't admit been wrong now enjoy the ownage liek a man..hahaha

7% is like 2 frames man is nothing.

And there goes the spinner..

Another information that PC Games Hardware has directly from the developer : Project Cars will support DX11 multithreading , making it the second game in DX11 history at all that supports this feature . Simply stated , it allows the driver commands by rendering processes outsource to multiple CPU cores . This has the obvious advantage lies in that the graphics card on the CPU limit is not as strong thwarted , as was the case earlier than just a core could be used for this purpose . Then the graphics card had to simply wait for the CPU and could not realize the full potential of their computing power so . Who has a fast processor , benefits from this feature , of course to a much lesser extent than systems whose CPU is relatively weak compared to the GPU . Previously used only Civilization 5 this feature .

http://www.pcgameshardware.de/Project-CARS-PC-238576/News/CARS-907019/

The game is multithreaded is not juts by default because it was change recently,so if you want to you have to enter a command line to enable multithrading.

Command Line / Launch Options

Steam Startup parameters (right click Project CARS/Properties/Set Launch Options - Multiple strings separated by a single space):
Multi threaded -dx11mt
Cap Framerates -fpscap xx (ex. -fpscap 60)
Launch 32bit -x86
DirectX 9 -dx9
Disable crowds -skipcrowds
Disable VR headset support -novr
Disable join in progress (multiplayer) -disablejip
Number of physics threads:
-pthreads 1 / -pthreads 2 / -pthreads 3 / -pthreads 4
• Default physics threads = 2

http://forum.projectcarsgame.com/showthread.php?23045-Command-Line-Launch-Options

And that doesn't change the point since the argument here is that the problems with DX11 are not been carry to the XBO which is proved by his post.

7% is total bullshit hahahahaa...

How would you know any of this wi- I mean do you ever post anything on here th- forget it.

Another developer claiming improvements with dx12 and Toroknowitall claims the improvements are nothing. What he seems to forget is he made consistent claims dx12 would make NO improvements to Xbox One. Yet again he is proved wrong.

hey we know you cant read and understand whats going on....so

DX9 in the command list means that its only single threaded method talking to gpu with that mode......

And DX11 has two methods in feeding gpu data, single threaded and deferred multithreaded, DX11 is multithreaded in general but fact is that Pc version single threaded gpu commutation weakness in the game pokes through namely on AMD based gpus.

Seeing i3's at 3.2ghz performing nearly on par with FX8's at 4 ghz and i5's performs within 5 fps of the a true eight core i7 haswell-e. If the game was coded for DX11MT correctly, Any of the FX 6's should have been able to match or beaten an i3 but they didnt, and shouldn't have seen an i3 performing within 3 fps of an FX8350. The game has an issue with it defaulting to DX11 single threading method. This is why with users moving to Win10 beta they see 40% gains coming from Win 7/8 with DX11. Win 10 drivers forces the game to use DX11MT.

Can't wait to see this on PC, going to be great to get a free 30-40% performance increase. PC gaming...always on top!

There's really little reason to buy a new graphics card right now (unless you have a dire graphics card), the OS is going to be the upgrade it seems.

Yep such a big lemming all I have is a PS4. Stupid is as stupid does and you El Tormented are stupid.

Sure I can admit when I'm wrong and since I said you're a loser and an idiot I'm not actually wrong. Go back to your moms basement kid.

You got Onwed..hahahaaaaaaaaaaaaa

I told you it was for PC so this is the second time a thread which claim certain win for xbox one backfire...hahaha

First was 20% Fable now 40% Project cars the only difference is that in this one the developer actually put a number on DX12 winning 7% which is kind of pathetic is 2 frames or 3 nothing when the damn xbox one version is as much as 14 FPS behind on Project cars..lol

 Project Cars will support DX11 multithreading , making it the second game in DX11 history at all that supports this feature .

Ass nice of you to ignore it..hahahaaaaaaaaaaaaaa

Again the XBO is not suffering from the PC version problems,so DX12 will only bring 7% which in reality is 2 or 3 frames and on PC 40% which is much more.

My point was proven and you look like joke for riding the secret sauce..hahaha

You never admit been wrong here and you are a lemming now keep the tears and denial going,enjoy the ownage..

Hahahaha.

Well this didn't half backfire! Can't believe some lems seriously thought there'd be a 40% improvement on the Xbox after it's been let slip on multiple occasions that the improvements will be slight.

From 40% to 7% haha

Not ignoring it, your ignoring the facts at hand lol, fact that AMD gpu's are seeing nearly half the performance that they should get means that the game is not using DX11MT correctly its defaulting to single threaded method that is coded into the game.

And to the fact that even with a Nvidia gpu AMD 6/8 core cpu's aren't even giving i3's a run for their money. Which proves that DX11MT on pc is shotty.

The X1 is not suffering from the same issues as PC...... because X1's performance is better then R9 290x's or even a gtx 760, even with i7 haswell's which are all multiple times faster. The fact that they state 7% or more means they dont know how high they can get performance from the porting over patch. If they were to go from the ground up with DX12 that 7% or more would be more in line with 15% or more. They stated "DX12 will add probably 7% or more for us"

That 7% should not be used as a foot note into what DX12 will do for a natively coded game.

Fallow by Frosbite quote about helping and a Metro developer quote..lol

7 or more percent improvements on top of 5-7 percent improvement patch is better than your DX12 will do nothing on XBO claims. 7 or more percent improvements could mean the difference between sub-30 fps and reaching 30 fps sustained and I have stated this view point in the past. There's a threshold with acceptable frame rates, before the developer switches the game from 1920x1080p down to 1600x900p i.e. not reaching 1920x1080p/30 fps may cause the game to be set at 1600x600p.

DX11MT is a requirement for Windows 10 i.e. AMD can't drag their feet on this issue.

Oh man, we talking about this again? :(

7% is from DX12,the other 5 to 7% is on DX11.X not on DX12 so yeah you can't count that improvement as been part of DX12,this is the lamest argument yet by you,and just show how badly you got burn from riding the xbox one.

Project cars is not 30FPS is 60FPS but drops frames like hell on xbox one,so 7% boost over 40 frame is 2 or 3 frames is nothing on a game were the PS4 command as big league as 14 FPS.

Oh and that 5 to 7% gain also apply to PS4 confirmed by that same developer.

So yeah you were wrong on this one as you claim it was for xbox one the 40% and it wasn't you can't scape your quote this time.

Yep..hahahaha

Yes you are and the biggest one is the fact that DX11.X on xbox one doesn't have the same pitfalls DX11 on PC has,which i have months telling you.

Wrong, DX11.X has the same cpu to gpu commutation limitations as DX11 you fool. When your coding for set piece of hardware ie a console you can tailor it to fit abilities.The devs do not have full control over the game and how it allocates the cpu, since it can use a multiple of types API's DX9 DX11 ST and DX11 MT.

Fact is that When you go to Win10 it forces the game to use DX11 MT, and you can see massive differences.

That's "7 or more percent"(get that right) when porting existing PCARS game from DX11 MT to DX12 i.e. it debunks your "DX12/GNX like" being equal to actual DX12. XBO vs PS4 means nothing to me i.e. I don't own any game consoles, past, present and future.

I have already stated XBO's GPU will be ALU bound when it matches PS4's 1920x1080p ALU based shader processing.

PCARS's "40 percent" was the mistake from developer and did not read topic's context i.e. Xbox's forum with Xbox One's frame rate issues.

I have already stated in the past DX12's percentage gains are dependant on the game.

http://www.eurogamer.net/articles/digitalfoundry-2015-project-cars-face-off

As established in our earlier analysis, PS4 does also have an advantage in performance. To re-cap quickly, Project Cars' read-out is typically 60fps in its career mode, with tearing and drops below 50fps once rain kicks in. Stress-tests also show a PS4 advantage once 30+ cars are engaged, while Microsoft's platform takes a bigger hit on hectic races with heavy alpha effects. Tearing is constant in these 30-40fps stress-test scenarios, but in the interest of keeping render times as close as possible to the 16.67ms target, dropping v-sync helps to keep the visual update as rapid as possible - if at a cost to image quality.

As I stated earlier in the year, DX12 gives an extra head room for additional frame rates.

DX11.X's 5 percent + DX12's 7 percent helps XBO's overall frame rate issues.

So multiplats now :

PS4 - 1080P

Xbone - 900P

After DX 12 wizard potion :

PS4 - 1080P

Xbone - 4K
