PhysX Flex

NVIDIA said:
PhysX FleX is a particle based simulation technique for real-time visual effects. Traditionally, visual effects are made using a combination of elements created using specialized solvers for rigid bodies, fluids, clothing, etc. Because FLEX uses a unified particle representation for all object types, it enables new effects where different simulated substances can interact with each other seamlessly. So far we showed examples for rigid body stacking, particle piles, soft bodies and fluids.

I really liked the Flex demonstration, especially the part with the water-filled soft bodies. Making soft-body physics, rigid body physics, cloth simulation and liquid simulation play nice together at real-time framerates isn't easy.

Did he say 30fps on a Titan in the Fireworks video?

Yes.

60fps (or more!) with a high-end Maxwell card? Could be.

Basically no one will use it for the next three years.

That's how it's always been with these demos. It (usually) takes years for tech demo features to appear in games.

FACE said:
I think that's a problem of the art rather than the tech.
Click to expand...
Exactly. These demos showing off a single feature pretty much always use programmer art i.e. no "real" art direction is used.

Flex look very cool.

but do Nvidia have any new plans to let more dev use their tech in PC games? because as of now we have few developers and even less games that uses PhysX and other Nvidia tech in PC games.

These, I am pretty sure, are designed as DX plugions for game engines that allow these effects (realtively easy integration).

They most likely are IHV agnostic in some ways too (like their APEX fur).

What sort of hardware are we looking at before developers can implement what was in that PhysX Flex video into games and still get 30/60fps?

It's a shame that not one of the consoles went with Nvidia this generation. I'd like to see more of this stuff in games.

I love that clothing tech. I hope this gen we can see non clipping between hair and clothing though. That's my biggest pet peeve

Pretty nice, hope it won't be Nvidia exclusive because I mean there is only one system use Nvidia.

impressive. i think we'll start seeing pc versions of games from publishers close with nvidia (wb/ubisoft) utilising this over the next few years.

Yes, that was really exciting and I hope we can see plenty of good uses in console games too :). I would also like better snow simulation to come to console games as I am a bit tired of the thick sheet of ice with some particles blowing in the wind here and there kind of snow simulation that we have now. It is why I cannot really take skiing games seriously.

THe light transmission in the faceworks demo is interesting. Must not be a complete screen based solution if they can get the ears to look the way they do.

Impressive stuff. The ocean looks glorious. Oh and the faceworks face reminds me of Nathan Drake for some reason.

NVIDIA GI Works tech paper from GPU Tech Conf 2014: PRACTICAL REAL-TIME VOXEL-BASED GLOBAL ILLUMINATION FOR CURRENT GPUS (PDF)

NVIDIA said:
CONCLUSION

* Fully dynamic GI becomes practical on mainstream GPUs
- Low end GPUs can benefit from much higher quality AO

* Future work
- Further reduction of aliasing issues
- Reduce the amount of content changes necessary

Planned to be released as NVIDIA GI Works library

Pretty good even for small objects, they just need fix shadow radius and implement some sort of high fidelity AO for smaller geometry.

FleX is finally nearing release. It's in closed Beta, now.

I remember reading a blog post that suggested it would be closer to the end of 2015 before FleX had a general release. Though maybe that would be as part of PhysX rather than a standalone.

It's funny how 'old' and relatively simple the basic tech of FleX is...it's just we now have enough computational power to do it with enough particles to make a more general framework with wow-worthy effects. It'll be even better in the future... there isn't enough power yet to do in realtime what something like Houdini does offline with the same kind of solver, but that we're starting down this road now is great. It's kind of now 'just' a case of scaling the particle numbers (& iteration count) up and up. http://vimeo.com/113441818

Extremely impressive, best physics I've ever seen.
Can't wait to see that in non-Ubisoft, Nvidia sponsored games.

Fucking FC4. Even PC users got the godray downgrade.

Working PCSS, TXAA, furwork that won't bring down a beast of a rig? Nope.

Advertised with lovely trailers and
detailed performance pages from Andy
? Yep.

At least Watch Dogs managed TXAA and AC managed PCSS. Good job I guess.

True fur simulation is inherently expensive, no way around that. The god rays seem more subtle to me after the 1.5 patch but I would not call that a downgrade since they're still there. PCSS is not that well implemented compared to previous examples (AC4 namely). Always disliked TXAA so it's a non issue for me.

I very much appreciate Nvidia getting involved in my favourite games, please keep it coming, it only brings fantastic stuff to me as a Geforce customer.

Nice, but these will probably be the luxury settings first turned off by gamers in need of playable frame-rates, at least for a few years.
