DirectX 12 reported performance gains of up to 50%

In April of last year, bgr.com posted an article[1] that reported "the same hardware will suddenly see a doubling of performance[2]" with the new DX12 API. It seems these rumors have partially come out as true. Today, Phil spencer, Head of Microsoft's Xbox division, announced

"What we've done with directx12 is we've given developers much more fine control of CPU and GPU, giving them direct control, and for CPU-Bound games, this will actually increase the performance of those games by up to 50%". [3]

 

 

Not quite doubling performance, but I think this could have a pretty big impact on the Xbox One in addition to PC's. Xbox One has about 29% less raw graphics performance (in TFLOPS)[4] than the PS4, but if DirectX12 can manage to reach half of the possible performance gains in CPU-bound games (25% increase) then it may bring the Xbox One neck-and-neck with the PS4. Could we see a repeat of how the Xbox 360 and PS3 were graphically matched, but it took the whole generation for developers to figure out how to code on the PS3, except this time Microsoft is left behind?

Wouldn't this have them ahead or at least neck and neck though, that is if the API is exclusive to Xbox One on the subject of the consoles?

mantle said the same thing... turns out it was a lot less...

 

but we can hope.

 

 

I wont be hoping though. because my 6950's dont support DX12 :( sigh

Can't wait to see the first DX12 games especially Star Citizen.
This should hold my GPU afloat till Pascal releases.

They lied up to 50%.

Nope, DirectX12 won't really do anything for the Xbox. Developers already have full control on draw calls, CPU, GPU and optimization. It'll just be Microsoft "Mantle" that's all you should expect.

I swear I saw another post just like this when DX11 promised increases like this.

There we're none.

The increases are in cpu bound scenarios, its not going to magically double your fps all the time. The biggest gain will be to minimum framerate, not average framerate. When I had my 280x I got massive improvement in minimum framerate in bf4 when using mantle compared to dx11. dx11 had awful frequent fps drops to 40-50 fps on some maps (such as seige of shanghai) regardless of video settings, with mantle I could play 60+ fps at all times, made it feel a ton smoother overall without those drops.

That's probably the single absolute best case scenario. In most games we'll probably see a 20% gain at best.

Don't ask to ask, just ask... please 🤨

50% seems really high I'd say 15% at best if we're lucky, remember they have to do some solid marketing to target mantle and convince to capitalize on it.

The idea is that because DX12 is coming out over a year after the console's release, developers won't learn how to take advantage of the new API in a timely fashion.

 Xbox 360 and PS4 graphically matched? You are going to anger all those peasants..... 

 

Edit: Although..... I do suppose garbage and higher quality garbage is pretty similar...............

Didn't they show a demo which showed off an extra 100,000 draw calls at double the frame rate?

Yep:

We will probably see a 3DMark DX12 benchmark this year.

I will only believe these claims once I see quantitative data and an independent analysis of DX12 - i.e. a video from Linus or Logan, etc. The key phrase here is the claim made by MS's head of console peasantry, Phil Spencer, of "up to 50%" - this will probably be true for a number of select, well optimised games, with emphasis on minimum framerate (as mentioned above - @bwat47). To be honest, a lot of this "performance improvement" stuff gets blown out of proportion with hype (which MS is not a stranger to) and we will probably see a similar outcome, as per Mantle.

 

I think MS's hidden agenda here is console peasant gaming. I believe they are just updating DX to create the persona that they are still committed to "supporting" the #pcmasterrace. When in reality, bias towards the #pcmasterrace would cannibalize the revenue generating capability of its console peasant division (CPD) which, MS has invested heavily in.

 

While it is great to see MS improving its DX platform, I am more interested in variable refresh rate monitors at the moment. Propogation of this technology amongst panel manufacturers is going well and should provide a better gaming experience for the entire #pcmasterrace.

Xbone is less cpu bound than ps4, so it will remain shite.

I'm not insulting anyone; I'm just being condescending. There is a difference, you see...

They already are for the most part. They are limited by stagnated cpu/gpu tech. Developers only have so much horsepower to work with. Can't make a prius drive down the autobahn as 300 miles per hour if you get what I mean.

Why does everybody judge the industry according to Ubisoft's games, just because they had 3 games with stuttering issues in 2014 we should not condemn the entire inudstry..

 

The majority of AAA titles work smoothly and look good at 1080p on performance-midrange hardware from both AMD and Nvidia.

He can say it will improve up top 50% but unless we are shown that is true, I don't believe it.

 

They lied up to 50%.

The statement is non-technical in nature and therefore open to interpretation.

What is going to improve by 50%. Is it minimum framerate in CPU bound screnarios? Is it average framerate? Is it another metric such as draw calls?

 

It's not an unrealistic claim as we have seen that Mantle can make a huge difference in cases where there are a lot of units on screen creating a CPU-bottleneck. Example check out the below minimum framerates on a high end i7-3960X CPU. This is an actual game, if Microsoft is using synthetic metrics they can probably get even bigger gains.
