This thing is very interesting to say the least. I recall on many occasions Oleg saying that the real challenge is to have enough CPU time to dedicate to AI/DM/FM. This thing has the ability to track and manage 6,000 particles with a gerat deal more overhead to come as the silicon and drivers mature.

Considering the $ people here have shelled out on HOTAS, TrackIR, pedals...it isn't crazy to say this may be the must-have peripheral for the sim-nut in 2006.

Interesting, I hope oleg know's about this..

Looks like a good first step. All the examples they gave seem like particle physics though. For flight sims to really benefit they would need to develop some sort of CFD module.

I wouldn't be surprised if there is a push for this on the industrial side. Right now CFD processing software goes really slow. IMO, it would definatly benefit in hardware acceleartion, the same ways that sound and graphics do currently.

My 2 cents, something to keep an eye on, thanks for posting.

This *is* a good idea.... This product however is not a great solution for the unique problems faced by a cutting edge flight sym.

The term Physics proc is used *very* loosely. It (and it's SDK) are alot more suited to processing "bones" than parasitic drag and stall.

Nonetheless a good idea and one I'm sure we will see growth in the future.

Anyone else old enough (like me!) to remember X86 CPU's with seperate Match co-processors?

Just like the old math co-processors needed a motherboard so equiped to accept and handle them this new PPU will need hardware support.

I think its PCI. All five of my slots are open, I've got space for it.

You use onboard sound? http://forums.ubi.com/images/smilies/16x16_smiley-surprised.gif Get yourself a soundcard it will improve your framerate a lot! Don't make your CPU do all the work when a soundcard can do it.

The motherboards soundchip uses your CPU which is already trying to run the game and all the other calculations necessary to play it. Do your CPU and yourself a favour, Audigy's are pretty cheap.

Unless of course you use Nvida's Soundstorm which is an APU built into the mobo. It doesnt use the CPU at all.

Well, considering the quality of AC97-chips, you got to remind yourself, that the CPU-usage is minimal. http://forums.ubi.com/groupee_common/emoticons/icon_biggrin.gif same for the quality http://forums.ubi.com/images/smilies/16x16_smiley-very-happy.gif - No way back from my AudigyII.

Anyways, the PPU us coming. GhostRecon3 and UT2007 will make use of this technology. Better save a PCI slot for it.

BTW: UT2007 will run on a 6800U with full details at least on 1024x768! http://forums.ubi.com/images/smilies/16x16_smiley-surprised.gif

It probably must be pci-express, because of the two way speed. When Xbox 360 is available, it might already be beaten by far of the Playstation.
A pc will pass the terraplops mark too, with more prossesing power in cpu, gpu and ppu. There is also sound prossesor coming with more power than a modern pentium 4.
Things like the vertex shader (water=3) can do, is in the gpu not cpu. Multiply this with the ppu, and it looks exciting for the pc-future.

It is incredible that the open pc platform has survived for such a long time. Still being an industrial standard, it is remarkable that is more than 25 years old! Cudos to IBM that did not know what they did then. The open structure has proved superior to all properitary sollutions.

The article in the link says PCI, with PCIe to come later.

I'm no computer expert, so somebody tell me...this will work in my lousy Gateway with it's Celeron? This is an up-grade for todays computers, right? If it is, I'm watching the tech support boards from this day forward. As soon as I see Steve or Hunter tell someone they've got it and love it, I'm putting one in my pc.

Same here for my Compaq Pukesario http://forums.ubi.com/images/smilies/heart.gif

It will be interesting to see a comparison test between dual processor board with one processor doing the PPU work and a single processor board with the PPU in the PCe slot.

I remember participating in a discussion about the possibility of such a card here on the forums...
