lol Physx cards for sure ! So get ready to pay up another 300$ to see the CT model fly when u nade him.............

Hehe that was meant to be sarcastic ! what i actually meant was there really is no need for $300 dedicated physics processor ! I really don't want to see every blade of grass being affected by the wind nor do i want to see how realistically bodies fly when hit by a rpg. Imho all this is possible by using whatever resources we have right now...........goldenfrag said:

True but there were no alternatives to accelerate games and such at that time nor are there now except for gpus. As for accelerating/simulating physics we have dual core cpus and gpgpu complaint gpus like x1800/x1900 series. Even Nv could take a similar approach. So imho $300 or even $150 is not justified. Right now i'll just wait and watch if MS has plans to integrate physics into the directx suite, something like Direct Physics. If that happens the physx api will simply be ignored..................zhopudey said:

Well, more horsepower will definately be appreciated, if we want realistic clothing on game characters. The cpu should be left free to handle AI ( I hope something like massive gets incorporated into the game engine 
hyeah
And the gpu still has a few generations to go before we get to Pixar quality. Motion blur, DoF, translucency, more use of HDRI, all this in realtime will require more number crunchers :bleh:

The day isnt far when we'll see separate cards for processing AI as well .............About the gpu reaching CGI level well, as gpus progress so does CGI so its a play catch game for the gpu. By the time gpus get to cgi quality level, cgi gets more detailed and complex.........So right now its wait and watch for me atleast.ZZz..
This means that there will be cards filled up in your system.
Lol.
1 PCI-e x16 Gfx Card.
1 PCI-e x1 Physics Card
1 PCI-e x1 AI Card
1 PCI Sound Card
1 PCI-e x1 Motion card..
Lol. :lol: :rofl:
I think we will be able to run games like FEAR and HL2 with 1000 FPS and no CPU if all this happens. Lol!

Yep right now all the cloth deformation, realistic clothing can be done with graphics. Also gpu involves texturing and shading polygons realistically, while ppu will involved manipulating and moving these very same graphics. If you really want realistic physics game devs will need to rethink the way they design games. Pre-rendered animation blocks, and simple state animation will be rendered incomplete. They will have to create and simulate real life itself. For e.g. For a realistic human model they have to create bones, give them properties, muscle, flesh etc and all of it will need to behave and act independently i.e. dynamically. Also creating say a scene with thousands of blades of grass realistically will also increase the polygon count dramatically. An good eg of this would be blowing a hole in a wall. You blow a hole in the wall and rubble, metal, debris fly out. There will be tons of particles which all will need to be shaded and textured. This is will slow down the game to a crawl (FEAR anyonezhopudey said:
). Smoke and dust screws even the best of the cards, forget simulating it real physics with realistic dust particles and smoke. So with increased physics will result in an tremendous increase in graphics processing power. Another situation would be the physics will not affect gameplay in a major way to make people upgrade. So devs would essentially require to make 2 modes for each game. One ppu accelerated and the other plain jane version thus bloating development time and cost (especially the ppu accelerated mode) . Until the time gpus become more powerful or sli/cf becomes cheaper and affording such a solution is cheaper we won't see much real usage for "realistic" physics. Just my 2 cents.

:bleh: I was only referring to the realistic flapping clothes
hyeah: That won't increase graphics requirements. Smoke, dust and fire, of course are totally different things! So are fields of grass. Just think, one frame of Monsters Inc took pixar almost half an hour to render! :crazy: So, we have a very long way to go.
Just one ppu and a couple of gpus won't cut it.And as for your comment that ppus wont add anything to the gameplay, well, neither do gpus :tongue:

Well depending on the number of player models, npcs etc on the screen it will put a strain on the graphics if the number is quite huge.zhopudey said::bleh: I was only referring to the realistic flapping clothes
Yep both graphics and physics still have a long way to go. But only with insanely powerful gpus will realistic physics be possible. I know its confusing but you must have got it if you read my posts above.Smoke, dust and fire, of course are totally different things! So are fields of grass. Just think, one frame of Monsters Inc took pixar almost half an hour to render! :crazy: So, we have a very long way to go.
Well true but gpus have reached way beyond acceptance. Plus not getting a gpu is not an option since all games have accelerated graphics. Its a general acceptance on the part of game makers and public something which the ppu will need to achieve in face of competition i.e. mainly gpgpu and dual/quad core cpus. Hell even kameo elements of power which renders 1000s on orc like creatures on the x360 dint require a ppu
The actual computation of physics is less resources intensive but the graphics computations as a result of those are huge !! Another field that requires progress is A.I. Stalker was all set to revolutionise that with its Life simulator system but sadly the game is delayed to 2007.

^ Yeah the Meqon physics demos were far impressive than anything I've seen in actual gameplay and they don't require any kind of dedicated physics processor.
