|

Nvidia has brought out new drivers that allow the geforce 8* range of cards to do gpu physics. (I have a 8800GTX so got to test it out)
The demo's do look nice(I especially like the 2nd liquid demo with the nvidia logo and the liguid in it) and you can notice a huge speed increase. (I tried warmonger earlier and that game lagged a lot, and now it actually plays smooth)
I tried playing arround with it with the SDK, but can't get a speed increase with it on normal rigid bodies (spawned a thousand cubes all falling on top of eachother). With physics gpu enabled or disabled, it's the same speed.
Could be I missed a config, it only works for liquid or those demo's are the only thing that the new drivers will accelerate
So, what's you're thoughts about it ?

it looks interesting, but i doubt it will be anything revolutionary.

PhysX was designed by Ageia where it brings physics to games on a hardware level. CellFactor was a demo game designed from the ground up to show what the Ageia PPU is capable of and with the final version called CellFactor Revolution. The adaptation of the PPU was so bad, instead of selling the game for $20 bucks (read it on their forum) they decided to release the game as free download hoping people who download it will get themselves a PPU card.
The Ageia PPU the card cost $300 and with that price and lack of games it's basically dead in the water to begin with, plus it's PCI instead of PCIe.
Nvidia bought Ageia and stated their GPU is also capable of doing physics thus the physical part is gone and now physX is implemented into Nvidia CUDA drivers.
As for this Nvidia physX demo I've read somewhere on the web that it does not claim to do what it's supposed to do and it's heavy on the cpu while other says it does not.

Well if they had demos showing improvement with rigid bodies, then I'm sure it's possible.
