Keep in mind two things Gibbo, UE3 is being scheduled for the next round of consoles, and will probably be heavily console optimised....... then figure out if it's AMD or Nvidia in those consoles, ALL of them
erm, UE3 is the current version already used in lots of games, I think you're referring to UE4
and then figure out what hardware Epic have been using all this time to develop it on...

Samaritain demo isn't applicable to real time due to the non addaptive tessellation implementation. 680 wouldnt handle playing that in real time unless they have implemented adaptive tess(im writing a thesis on it!) defo possible to have it real time though.
erm, that video IS realtime, people on this here forum (like Gibbo) have seen it running real time on a single 680
at least that is what Nvidia/Epic are telling everyone, unless you want to say you KNOW different?

yes its been watched, but it hasn't been played. The tessellation uses pre determined factors and is not adaptive. Lack of adaptive tessellation means the gpu will have to constantly render everything at a micropolygon level which would be insane and would certainly not be in a playable state. However flip adaptive tess on and you've got a perfectly good to go interactive demo.

"In the Samaritan demo, the protagonist’s face "blends between three different stages that adjust the shading and displacement over time," explains Mittring, and to "expose the details of the texture used in the displacement map, we used higher tessellation levels." NVIDIA’s Dudash continues, stating that the tessellation was achieved through the use of the Flat method, which is the fastest, "because we don’t do complex math for splines or other elements," and that the level of tessellation was set to factor six when he transforms.
"This works for the demo," explains Dudash, "but in a normal game situation, you will want to use dynamic tessellation to reduce the tessellation factor when objects get farther away from the camera, or are not seen. In Unreal Engine 3, enhancements will be added that enable this dynamic tessellation," which will help to dramatically improve performance in a scene, and pave the way for full-screen tessellation of every object.
This is the standard Tim Sweeney, Epic’s CEO and Technical Director, sees the industry moving towards over the next however many years."
Obviously if they have utilised epic's now current tess standards then its all good and i've no doubt a real time playable demo is available. Would be an awesome achievement for game development. I just didnt see anything listed about it at the nvidia conference mentioned.

It's old, but it's still the best looking tech demo out there, and this, unlike most will actually be used in future games.
Shouldn't make a difference what GPU's the console use though, as we all know it doesn't work like that.

forget 4 680s they should make it so you could do 4 690s 8 GPU sli and your own little power generator to power it so you wont black out the street

I think you missed his point
I think he worded his point very poorly in the first place, what he said was that a 680 couldn't render this in real time, what he meant was that it was a scripted scene and not indicative of gameplay
his point is kind of moot anyway as Epic have said that they've already coded adaptive tesselation in to the latest UE3 tools, just that it wasn't needed for this scene as it is scripted
edit: when I say latest, I mean as of nearly 1 year ago

i already said and accepted they have implemented it :/
they still havent implemented phong tess yet which would again be better off for the engine and real time gameplay. AMD have started too through the programable shaders though.
End point is its not a real time game, its a scripted tech demo. I was only interested in Gibbo marketing it as they would be showcasing something soon, but untill we know what he has seen then :/
Are we really going to get like this and throw white papers and key notes at each other? I've just written a thesis looking into the technology and simply cant be bothered. I just want a real time interactive version, like anyone else.

hang on
you start off by quoting some massive chunk of article about the tech behind the demo at me and when I respond by showing you that adaptive vsync has been part of UE3 for over a year you respond by saying that it's not neccessary to start quoting articles to each other?
erm... one sided much?

Don't say it like it's a fact, it's only your opinion.
Imo Crysis is an awesome game and I really enjoyed Crysis 2 all the way through, and so did a lot of my friends. Can't wait for Crysis 3
This is the same engine that ran UT3 and Mortal Kombat just used really well. Most engines are limited more by what the designer can do with them than what they can do, i.e Half-Life used a modified Quake 1 engine and was IMO better than most stuff using the Q2/3 Unreal engines.

to be fair to developers, they have also been adding more tools to UE3 in the last 1-2 years that haven't made it in to games yet - this tech demo was to show off some of the latest bells and whistles to try to get a) the console makers to give the next gen of consoles a bit more juice in preperation for UE4 (they did the same thing with gears of war to get microsoft to put more VRAM in to the xbox360) and b) to show games studios what they *could* be doing if they choose UE3 as their game engine/development kit
