amd have worked closley with tomraider games for years cough cough tressfx anyone ?

Yet there is no AMD logo or credit in sight in ROTTR. There is a Nvidia logo though

Not for Rise of the Tomb Raider, only thing of AMD in there is Pure Hair which is down to GPUOpen, their open source libraries.

The game is still sponsored by NVIDIA and a Gameworks title.

Nvidia would rather jump off a building than pay AMD a license fee to use ACEs and async compute ( which i think is patented by AMD )

Of course Nvidia DX12 driver holding back Ryzen. So it is nothing new but the same thing been happened to Nvidia DX11 driver holding back multi-threading very long time ago.

AMD never gave Ryzen CPUs engineering samples to games developers, Intel and Nvidia since it taped out back in Jan 2016. AMD did shipped PCs with retail Ryzen CPUs to games developers after Ryzen launch but not to competitors Intel and Nvidia!

I am sure Nvidia already bought Ryzen CPUs and AM4 motherboards after launch and Nvidia DirectX driver team are now working on DX12 optimizations for Ryzen CCX.

Lol it's hilarious reading Loadsa posts, i hope Vega smashes Nvidia, just for his reaction, but I'd get a paramedic and a counselor on standby haha.

Been saying it for ages, AMD hardware was built with low level API in mind, hence DX12 and Vulkan gains, Nvidia hardware is built for DX11 and DX12 / Vulkan is handled via software, hence why they are garbage at it

Lol. Damage Control is here.

The funny thing about rise of the tomb raider too is this:

No mention of AMD for the tressfx code for "purehair"

Pretty sure nvidia held a gun to the developers head to get them to add that piece praising nvidia

Its only a fail as it hasn't took off, when it was announced by MS, they said there would be about 25+ titles )or something like that), that fall, well, where the **** are they ?, as here we are, a couple of years later, and we're still waiting, all we've got is a couple or so Dx11 games, that have had it patched in laters, FAIL!, and i doubt any 290 owners are miffed at running Dx12, its a performance boost for them, they'll only be miffed at the lack of its usage id have thought.

nVidia don't need ACEs it is just one approach of many and doesn't fit their architecture - you can't really patent async compute.

AMD did put it on consoles, on their GPU and even managed to integrate it to the 2 new APIs on PC, maybe you cannot patent async compute, as graphic and compute simultaneous processing, but i am pretty sure the way it's done by AMD, probably has been patented, and finding another way without heavy drawbacks, is not an easy task.
all of this is just guess work on my part, because at first, i thought Nvidia was intentionally slowing down the feature to benefit as long as they can from DX11, but 2 years later seem a bit much, with no alternative in sight, so maybe there is more to it.

Am also sure Nvidia told them to change the name from TressFX to PureHair

With it being open code people can call it anything they want!!

TheRealDeal · 1 Apr 2017 at 17:13

Possibly not as i am sure it's called PureHair in Deus Ex as well which is an AMD partnered game.

Deus Ex Mankind Divided uses - or atleast has all the files for - nVidia's hair physics stuff which is odd.

I know they had purehair in the presentations but no mention of what is actually used in the retail game.

Id love it if it did, but it won't.

What if the devs/publishers innocently offered to change the name if Nv just simply bought X amount of guaranteed sales, surely that must suggest the possibility that Nv didn't tell them to change anything?

Because TressFX wasn't solely AMD's creation, it was made in collaboration with Nixxes.

Maybe they have the rights to do what ever they want with it-which can include devs/publishers stabbing a vendor in the eye for cash, but kiss and make up with more cash like they usually do?

Yet another potential annoyance to add to the minefield of hardware buying for pc gaming. It is getting pretty tedious. if you want good dx11 performance you have to go Nvidia, if you want good DX12 you go AMD (well, you do when Vega comes out potentially as there is no competition at the high end at the moment). Now it looks like which brand CPU further changes things in this regard. Then add all that to the fact you have to decide which gpu manufacturer you are going to stick with for adaptive sync (a reason i won't buy an adaptive sync monitor) and the whole thing is a **** show.

Goldblum · 1 Apr 2017 at 17:27

I`m still interested in AMDs claim of increased bandwidth using Ryzen + Vega...

Okay, but it's not actually that bad.

AMD made it opensource but not sure it was a good idea to not have a requirement to credit them for the underlying technology.

The cpu brand can be any if you go for an AMD card. At the moment the Nvidia gpu's appear to gimp Ryzen significantly and also don't perform that well in Dx12 on Intel cpu's compared to AMD gpu's. Unless Nvidia identify and fix the issue with DX12 it's AMD gpu's for DX12 for the foreseeable future.

pretty sure their credits are in the credits section

also Nvidia are releasing big DX12 patches soon

They already released a DX12 Driver couple weeks back.
