APEX Turbulence and Dynamic Fur – now in Call of Duty: Ghosts
As promised earlier, PC version of Call of Duty: Ghosts title was recently patched to include a set of GPU accelerated physics effects.
Update: Dynamic Fur – technology overview and comparison video
New NVIDIA’s dynamic hair and fur simulation technology is making a debut in this game. It allows to realistically render and simulate multiple strands of fur on animals characters such as Riley the Dog.
In addition to the nice look (especially in motion), Dynamic Fur feature is utilizing DX Compute, according to the information we have recieved, and thus should be available to AMD users as well.
APEX Turbulence based volumetric smoke simulation has also been added to CoD: Ghosts. It is using latest APEX 1.3 SDK and Particle Shadow Mapping (PSM) feature for enhanced visual look of the effects.
In comparison to Fur, Turbulence effects are exclusive to NVIDIA GPUs.
Unfortunately, Turbulence smoke can be enabled only in multiplayer, is applied to a limited number of assets (smoke grenades, for example), requires some tweaking and in general is not that noticable.
Performance effectiveness of the added GPU physics effects is yet to be evaluated.
It’s weird that Nvidia did the fur via DCU, I would have expected them to use CUDA.
Why did they do that ? It’s great that AMD owners can enjoy the fur but I woud have thought Geforce GPUs could have fared better with CUDA.

The Turbulence smole looks very similar to AC4’s :

Well, maybe they have decided that it is time for GPU PhysX to support more platforms)

Doesn’t GPU Physx already works on PS4/XBO via compute ? Or does it run on the CPU ?
I was under the impression that Physx could already run on GPUs not featuring CUDA.
Anyway, for now it’s limited to the fur tech. I wonder if the whole Physx system will be designed to work via compute and then compatible with AMD GPUs and the PS4/XBO.
Maybe CDP will find a way to implement the wolf fur on PS4.

I have this game on PC and with 2 Titans in SLI and even a 650ti as a dedicated PhysX it runs horribly when the dog is on the screen, or the Apex Turbulence in MP.
Goes down to about 25-30 FPS.

I even noticed that my dedicated PhysX card shows 0% GPU usage after playing so that’s my best guess as to why.

Fur tech is a pretty new one, maybe it yet can’t run on dedicated GPUs, especially if it using features like CUDA-graphics interop.
