Gameworks on AMD

[Fidgets]

Is there anyway to enable Nvidia features such as Interactive fog/smoke and interactive paper debris using an AMD card? I can enable Enhanced Rain and Enhanced Light Shafts. I am using an AMD R7 260X 2gb edition. The game runs fine with 30+ fps despite the requirments with some .ini tweaking. Any help is welcome. Thanks.

nope

there must be a way ? i hope so because i hate this that i cant enable it with my amd

Even if you could enable it, it would cripple your performance as it was designed with NVidia cards in mind, and is not optimized at all for AMD cards... And you aren't missing on much in the first place. If you absolutely must run GameWrecks then sell your card and get an NVidia one, but even then you would notice performance issue with it turned on, it rarely runs flawlessly even on the most powerful NVidia cards.

No, there is no way. I also strongly doubt NVIDIA would make it so easy or even possible to enable it on cards of the competitors. At least Gameworks are made as a incentive for buying NVIDIA cards

AMD GPU's are incapable of running any kind of PhysX code. If you enable any PhysX feature in any game w/ an AMD GPU, then all PhysX effects are done by your CPU, not the GPU.

If you have a high end CPU, you can usually get away w/ the 'Normal' PhysX slider in games. If you do 'High' w/o an nVidia GPU, then your game will lag immensely since no CPU can run the 'Apex' part of PhysX very well.

aha ok ! to bad, i only got 2 options of gameworks enabled. i like to see the fog feature but i can live with that.

I notice though that all Nvidia gameworks feature work on my AMD card in The Witcher 3
P.S. I upgraded my card to an R9 390 8GB edition

Yeah, quite a few GameWorks features are completely independent of PhysX.

However, in this game -- Interactive ... means PhysX. The "Enhanced" nonsense can be used on any system, but enhanced rain is barely visible and enhanced lightshafts have basically the same problem as HairWorks - they tax the bejesus out of tessellation and don't even run well on NVIDIA's own hardware :P

Ok. Thanks for the clarification.

There IS a way to do it, called Hybrid PhysX, but it's unsupported, requires hacking your drivers, and requires an Nvidia GPU in addition to your AMD one. Basically you hack the drivers to allow the PhysX stuff to run on the Nvidia GPU (which can be a lower power one like a 750), whiel the AMD GPU does the rendering.

Nvidia doesn't permit this with their drivers...I'm of the opinion that this type of forced lockout should be illegal (they are effectively denying you the use of an Nvidia card you purchased because your other GPU isn't theirs). So it requires third party hacks. It does work, but game compatibility varies, Nvidia is always trying to break it, and the hackers are always one step ahead of them and making it work again.

This is why I believe that physics accelerators should be independent of the GPU, like it was when Aegia first made PhysX. I'm of the opinion that Nvidia should never have been allowed to buy them. The actual PhysX code has been released to the public by way of UE4.0, and it would be possible for someone to port that to OpenCL, at which point it would run on either AMD or Nvidia.

I think it's really stupid of Nvidia in the first place, because if Hybrid PhysX was supported, Nvidia would *sell more cards*. A lot of AMD users would pick up an Nvidia GPU for PhysX.

What you talking about my i7 5960X@4.2 can.

No CPU can run the high physx code. When you get a 1000+ core CPU then maybe. 8 isn't gonna cut it. This type of code requires MASSIVELY parallel execution, something that GPU's can provide. CPU's cannot.

My cpu was £1100 pounds it can handle extreme level of physics X.

Depends on the feature. Vendor specific features like PhysX? No, you can't. But stuff like the smoke and weather, or even witcher 3's hairworks, are just a part of gameworks. Gameworks is NOT vendor specific, it is just a set of tools created by nvidia that assist in creating special effects for a game that are very tesselation heavy (something nvidia cards are good at doing).

AMD chips can and should run these features just fine. There's always been vendor specific features in games whether its PhysX, nvidia fog (remember the early 2000s?), Mantle, Glide...but gameworks doesn't fall under this category.

PS: Interactive smoke may actually be based on PhysX/Apex. If it is, then yes it is only usable by Nvidia customers. Sorry.

mantle was designed to be open, so it was not vendor specific, it never left beta so it's source was never put up. It was going to be up to Nvida to make it work on their cards, something they never wanted to do. Infact they laughed at AMD for asking. jokes on Nvida though, as mantle was applied to DX12 and Vulkan, basicly making mantle itself unessesary. So mantle does not fit the catagory either as it was planned to be open source.
