The following is a demo of CellFactor which has been designed as the first game to use the new Physics Card technology that people seem to be talking about over in the hardware/software forum.

The problem was that you need one of these cards to run the demo, however if you append the following onto the end of the games shortcut

EnablePhysX=false

you can play the demo to check it out.
Sensus of opinion seems to be that with a high end graphics card, turning the PhysX card off or on doesn't make a huge difference, other than very tiny little delays/lag of objects moving on the screen, but not enough to spoil it.

Give it a go and let me know what you think

There was a video of this game going around about a month ago wasn't there?

It's on youtube http://www.youtube.com/watch?v=gSeW9NejxLo but I wondered what it plays like on your machines, as I am going to give it a go on mine which isn't great, to see how badly it struggles in comparison to say Mani4chicken's setup and so on...

Just trying to work out if this Physics Card nonsense really is a load of nonsense.

GRAW came with some sort of Aegia PhysX code, and put an icon in control panel. Don't know what it's supposed to do.

Yeah, I mean I haven't got the physx card, but it insisted on installing the stuff.

I know. Do they even sell them cards yet? I guess they must do.

yes they do now, ive seen one online for 200 quid which is a bit daft for something that isnt really supported by any devlopers yet.

EDIT: gonna try the demo out will report on the shinyness

oooh cell factor. I remember liking the video of it very much, then hoping I wouldn't need a physics card

I can't get it to work, it loads up to the menu but if I try to start a game it loads endlessly

Well on maximum everything it kills a 7950 no problem, however everything set to medium and its ok. Looks shiny and the amount of items on creen is incredible. I dont think ill bother with the cards yet until more developers adopt the physx way of life.

Heh, I guess most people will do the same thing, Valve will run another hardware survey, find no-one's using them and not bother.

I got it working and I'm very impressed. It runs quite well despite having hundreds of things flying about

I think there's stuff to take into account here.

Yes, you can fire a hundred simple objects about really easily.

However, the liquid and fabric stuff is massively complex and will bring your computer to it's knees pretty sharpish.

I feel some level of physics processing is inevitable - Though, what remains to be seen is how much is needed.

If the current rumours* are true, I suspect we'll see a hybrid, with the CPU doing the simple stuff like shitloads of boxes, and the GPU doing the pretty stuff like water that doesn't have to interact fully with users.

*That GPU physics works well for visual stuff, but is too high latency for interactable objects
