It’s not possible unless you have am major redesigned of how a CPU works in the hardware. No CPU out right now can do what a PPU or GPU can at fast speeds.

Do you know this for a fact or are you just guessing? If you know this for a fact can you post some evidence as all of the evidence I have seen points to the fact that the PPU and GPU will run physics calculations far quicker than a CPU. Even a quad core.

Regarding CPU v PPU/GPU performance is going to depend somewhat on the code surely. Certainly if the forthcoming DMM (consoles only so far) is anything to go by, CPU cores can do a rather good job if you give them the chance. Right now it really is too early days to call which will end up doing the job... who knows we may even see hybrids doing the job eventually e.g. CPUs with physics co-processors a la the old maths co-processors etc.
Gift.

maybe its the PPU and the quote button flies around the screen in a realistic cloth way, so he can't click it
Not had time to search for any new benchmarks but came across this on another forum.

The fact that you only got 15fps will be more to do with the speed of your cpu and lack of ppu than your RAM.
The physics calculations in cellfactor are very cpu intensive. Your CPU is not quick enough to run them at playable framerates.
The reason I ignore the quote comments most of the time is because the only people who have a go at it are the ones to happen to disagree with me about the PPU yet have no facts to post so intread they pick on my writing style and/or accuse me of working for Ageia.
5+years and 1000’s of posts on this forum and no one had a problem with the way I quoted now all of a sudden after 5+years of posting a few people who don’t like what I say about the PPU pick on the way I quote. Also in the none PPU treads no one complains about the way I quote.
The other reason I didnt repond to Mr Paul comments was I thought what he wrote was funny and he hasnt being wasn’t being serious.

I really wish someone would use a PPU properly, but they dont, so 1) give the cards away with graphics cards or somet 2) start making millions of games for them, and fast
Another point pottsey, good sir, it is true you -never- post on here in -anything- other than to do with ppu's, post in another thread occasionally, offer some insight to other subject areas, always good to have input into the forums over a wide range of subjects

Guys stop having a go at Pottsey. He can post where and how he damn well wants as long as he's not breaking the rules, which he's not.
PPU-bashers have a point in that at the moment there aren't that many games that use it, but in my opinion this is a necessary evolution of gaming. Improving environment interactivity and manipulability will increase the immersion of modern games. PPU will help achieve this.

I regular post in other areas and threads. Can I suggest you go on advance search type in my name under author. At a glance I would estimate 50% of thread I am in are none PPU related this month and a number of posts where helping other people.

The cloths and liquids are very demanding and cannot be done at fast speeds on the CPU. From technology point of view the physics are amazing as they run at playable speeds and contain physics we haven’t seen in none PPU games. You might not like them but that’s something else altogether.

Are you aware of the various forum wipes? I started sometime in 2000 to 2003 not really sure precisely. I used to post a lost mostly about PowerVR if you use the search button for my name you see reference’s to me dating back to 2003. I stopped after the last wipe when my account got lost and as PowerVR had nothing new out there was no reason to post anymore. There was about a year or year and half where I didn’t post. Then I came back when the PowerVR MBX and physics started to get interesting. A number of old forums members remember me and my PowerVR links with my name are still in the old stick 3dcard thread.

It pulled the FPS right down, and it was quite constrained to a box... plus it was mostly just a water shader and not full on liquid modelling...
A CPU could do physics very well... IF... it wasn't also running the rest of the PC - this is the key point - the other work load plus various latency/buffer issues due to the way its working to run your OS, handle the rest of the hardware, etc. means it doesn't work very well for physics processing, put your CPU on an addon board just doing physics and oh hello ageia...
