NVIDIA GameWorks Integration

[Tgirgis]

Hey guys, hope this doesn't push this thread off topic too much, but with the Physx CPU code being opened up I've been wondering a few things about GameWorks and Flex, and since some of you guys are already using the GameWorks branches, I figured this might be the best place to ask:

1. How well do the VisualFX libraries run on Non-Nvidia products (AMD and Intel iGPUs)
2. Anyone know if Flex will be Nvidia only? I heard somewhere that there is a planned DirectCompute version of Flex, but I haven't heard much since then.

Also, just a quick note, let's keep responses civil =)

Yesterday i tried Hairworks on maya and viewer. That was something! Actually i got beyond my expectation. I really did not expected that awesome result. Cant wait for it!

First of all, thanks nVidia for opening up Gameworks!

Since i'm not really a programmer nor deep enough experienced with graphical engineering, i still got some questions.
1. Is Gameworks, manufacturer independent or limited to certain nVidia cards? Mainly asking for HBAO.
2. Epic said that their SVOGI approach was rather performance heavy, how is VXGI doing in comparison?
3. Again i'm not a programmer so excuse if my last question sounds stupid. Is there any chance we can get single Gameworks elements as a plugin?

Thanks in advanced.

Hello!


When I click on the github link, I get the 404 page What am I missing?

Cheers!

You need to link your GitHub account in https://www.unrealengine.com/settings

That did the trick I'm such a github noob

1. HBAO+ should work on DX11 graphics cards, regardless of vendor.
2. VXGI has better performance than SVOGI, because the SVO part of it (Sparse Voxel Octrees) have been replaced by a more efficient implementation based on clipmaps. However VXGI is still a leading-edge feature and is not expected to provide performance of a baked lightmap solution.
3. The Plugin system doesn't provide the features necessary to provide the Gameworks modules. Source level integration is needed.

The Direct Compute version of FleX is still in development.

Anyone saw this? https://developer.nvidia.com/content...engine-4-games

It seems we will get this monster example when HairWorks will be released:

This is definately UE4 Editor (just like all the other pics). We need the HBAO+ sample too (I know Mike promised that the developer behind it will release it).

I am very eager to get the HairWorks-UE4 integration pushed up onto Github, but there is more work ahead before we can do that. The latest I heard is that HW will be available in mid-April. Sorry for the delay! The first release will have some rendering limitations, but we plan to follow up with rendering improvements within a month or so after the first release.

Thanks for the clarification and keep up the good work guys.

@Mike - you needn't comment on this, but I wanted to just quickly say that the work you and the other GameWorks crew are doing on FLeX etc. is *way* more impressive than what NVIDIA showed at the headlighter event at GDC tonight. :P Can't wait to dive into this stuff and also get it set up and working in my VR game. Awesome work!

@Mike On topic Off topic question. AMD (ATI) unveiled their Radeon R9 390X and it uses HBM and new stacked meory tech compatible with DX12.3:

I really don't know what Nvidia has in mind but this time they are late in the party for not unveiling their Pascal Cards first (but instead they unveiled teh GTX Titan X) which as an NVidia supporter (for many years) this really makes feel forsaken and neglected.
Like n00854180t said, You Mike and your time are doing greater and more impressive work. Good continuation. Looking forward to see NVidia unveil their Pascal cards at GTC so I can finally burry my useless laptop and get a new one with the new Pascal Cards, so I can run UE4 with no hurdle. Thanks !

Thank you very much for the infos. But in my previous post, I was talking about the Leaves sample for HBAO+ that you promsied its dev will release it. Looking forward to also see the water and sand shaders for FLEX . Thanks !

Oh thank god, it is true! I appreciate the response =)

Flex pakaging possible?

Hi,

Sorry if this is a dumb question but I did not know where else to ask.
I made a small demo using the fleX unreal engine version. I wanted to show what I made to a friend but when I tried packaging the game I got the error:

Is there fleX unreal engine not ready for packaging yet or is the error on my side?

Thanks for listening
