TRESSFX: A NEW FRONTIER OF REALISM IN PC GAMING
- Thread starter Final8y
- Start date
Its possible theres a PhysX path for the GPU on the PS4 if the GPU has been built with compute in mind (which raises some interesting questions) PhysX in software on the consoles has been possible for awhile. The primary physics path on Unreal Engine 4 is PhysX but there are also interfaces for Open CL, etc. if a developer decides to use them (not sure theres actually any other fully working physics pipeline available at this time tho unless a developer implements it themselves).
Seems to be one of the focuses for unreal engine at the moment, with UDK theres an abstraction layer between the designer implementation and the target platform or API thats actually used for many things and Unreal Engine 4 seems to have pushed that further so that the developer isn't necessarily forced to use a specific API/backend for features like physics, lighting, etc.

+1,
my 6800GT had a demo with the hair rendering iirc.
Would be nice for the advancement of PC gaming in the whole.

1. this sounds like amd's "secret" directx11 technology (tomb raider already looks phenomenal... would be great if it had gpu physics for everyone as well!!)
2. yes, like was hinted in the ps4 conference and like how many people surmised amd was coming up with a new physics tech, i'm both excited and hopeful for amd gpu physics. if both camps can do physics it means it's worth more for developers to put physics into games. good for everyone really - it'llno longer be a gimmick but an established technology.
edit: on second thought, tress = hair, there's a picture of hair, and tomb raider's protagonist is unusually female, with long hair... realistic hair seems about right. though the havok thing is still cool. given intel own havok, i'd still like to know how the ps4 runs havok

Are you talking to me Dave?
I'll answer anyway.
Its benchmark stable. Its not long term stable. Max my card can do without artifacts is around 1300 core and 1823 memory.
Yes i was and i still consider that pretty monster!!

Only as a tech demo though, still haven't seen it in game. If AMD can get this in real games ( and they might with their GPU's in PS4), then fair play to them.

Havok is a middleware solution, just like Physx. Half Life 2 uses Havok for their physics, its basically just software.
There are games that use the tech behind it for various objects, not sure if theres any game that uses it as hair like in the demo tho. (Theres a few random/obscure korean/japanese games that use PhysX/ApeX a lot more extensively than most mainstream AAA titles).

can you give some examples? i'd really like to see the hair thing in a game. just remembered the videos nvidia put out 2 years ago where they claimed games were gonna start having way better hair physics and it just never happened (or never came into the mainstream?) o.o
This further cements my thoughts that PhysX has been given its death sentence. No chance will it last to any extent now, barely anyone used it before, now it's going to be nobody.
What developer in their right mind would bother with PhysX when they could use something like this that works on any manufacturer's GPUs?

Talking beyond simple rigid body physics before anything will replace PhysX it needs to prove itself first - way too many Physic APIs have been big headlines and then dissolved away to nothing with not enough support and development put behind them to make it to maturity.
Can't remember specific examples off the top of my head, theres a few like passion leads army, etc. but I can't remember which use which effects.

None of that gets in the way of overcoming PhysX, PhysX doesn't have a lifespan because it's locked to nVidia.

In the presentation they talk about Physx on the PS4 GPU "Look at me how good am i"
Well, the PS4 GPU is the same GCN GPU that you me and every other Radeon 7### series GPU owner in the world owns.
I would not be in the least surprised if AMD one day soon just piped up and said "Hey guys, we have GPU Physx" and all the Nvidia fanboys in this world go NOOOOOOOOOOO!!!!!!!!!!!!!!!!!!!!!! and all the AMD fanboys go YEEEEEEEEEEEEEEEEEEEEEEEEEEESSSSSSSSSSSSSSSSSS, STUF YOU NVIDIA!!!!!!! STITCH THAT

One of two things may happen, Nvidia concede and simply use the same engine, which is what developers would want them to do given that they would like to port from PC to Console or the other way... without having to deal with multiple engines.
Or Nvidia get pig headed about it, refuse to change, and developers ignore Nvidia's engine, much like they do today.
It has to be said, AMD are really cranking it up.
Good, its about time!

I see it the same way, but this isn't a move by AMD. This was always going to happen really, since most games are developed for the lowest common denominator, game-changing physics was never going to happen until consoles had the ability to do hardware physics.
Now that they have the ability to do it, it can be used properly in ways that change game play significantly, and the fact that all consoles use AMD mean that it'll never be PhysX that gets the marketshare there because nVidia do not concede, they will likely continue to try and push it, but it will largely be ignored because it wouldn't make any sense at all to use it.
This is why I love the release of new consoles with significantly more power than their predecessors, because real game-changing things happen, the average graphical quality gets a massive boost, and PC hardware gets utilised better until it massively overtakes console hardware again.

The GTX 6## is OpenCL compatible, tho its junk, a 7850 is a fast as a GTX 680, if not faster.
There in lays the problem, Developers have X power to work with, only do then find X brings the other one to a grinding halt.
Well Kepler isn't very good at compute full stop really. AMD has always had more compute "horsepower" than the equivalent nVidia GPU.
