Delving into DirectX 12 performance

DX12 is very new and with these two games utilizing it, Hitman 2016 and Ashes of the Singularity, it is difficult to get a good sample of results to see exactly what the new API will offer.  [H]ard|OCP have been working with both of these games to determine the performance differences between DX11 and DX12 and to find where the bottlenecks, if any, are.  With Ashes they tried limiting the CPU, one set of tests at 1.2GHz and the second at 4.5GHz which showed how well DX12 lived up to the touted benefits of reduced CPU usage.  They also tested with older GPUs on a 4.5GHz CPU to see if the new API does indeed help out older GPUs.  They also delve somewhat into the confusion surrounding AMD's Asynchronous ace in the hole.

For Hitman they contrasted various GPUs from both AMD and NVIDIA while leaving the CPU alone for the testing.  This review emphasizes the performance delta between DX11 and DX12 on the same GPUs, and unfortunately also addresses some stability issues which DX12 has brought with it.  Read through the review to see what results they gathered so far but do not consider this the final word since both NVIDIA and AMD's GPUs could barely manage 10 minutes of DX12 gaming before completely locking up.

We still have a lot more investigation to perform before we can define the strengths and weaknesses of DX12.

"Hitman (2016) supports the new DirectX 12 API. We will take this game and find out if DX12 is faster than DX11 and what it may offer in this game and if it allows a better gameplay experience. We will also compare Himan performance between several video cards to find what is playable and how AMD vs. NV GPUs compare."

You're forgetting Rise of the Tome Raider.

Quatum Break as well also uses it, Tomb raider is kinda half *@#ed effort of it and you lose performance.

And forgetting Gears of War. And Quantum Break. But those (and Tomb Raider) aren't AMD titles so I'm not surprised Jeremy doesn't know.

To be honest, not a single one of those actually interests me but ya, I should have remembered the Tomb one ... not that any of them were tested in those two reviews.

I think I lost track, last time I was paying attention I was an NVIDIA shill?

And now you should only ever mention AMD.

Get with the times, Jeremy.

And now the Nvidia fanboys desperately need you to be an AMD shill so that they can discredit the things you said about AMD that weren't bad.

No positivity can ever be shown to AMD by anyone unless they're shilling for AMD. You know that, Jeremy.

OP, maybe take a look at the below link for list of games that currently support dx12:

https://en.wikipedia.org/wiki/List_of_games_with_DirectX_12_support

So far, there are 5 games that support dx12:

Gears of War
Quantum Break
Rise of the Tomb Raider
Ashes of singularity
hitman

Two games? lol come on. I'd expect better research than that on this website.

Still it is not many. And so far the result is quite underwhelmig for DX12. The only game that quite stable with DX12 probably Ashes. Honestly i'm waiting....waiting for the day for DX13 to save the day and see how dev complaining about DX12 haha

There is Killer Instinct as well, which is actually a relatively decent benchmark, considering that it runs without hitches, and since the NV cards are performing up to where you would traditionally place them.

Its only that AMD destroys them in direct comparison... shame gamegpu has no Fijis on hand at this time.

Killer Instinct isn't DX12
