Yes, I have no idea what most of this jargon means... So in the immortal words of Eggo: "Lol wut?"Onmi said:Let's get this out of the way.
Can you explain PhysX in detail to us.
The PS3s GPU doesn't support PhysX hardware acceleration though does it?Strelok17 said:"PhysX is a proprietary realtime physics engine middleware SDK originally developed by Ageia (now NVIDIA) as the NovodeX SDK. The software was PhysX can also refer to a PPU add-in card designed by Ageia to accelerate PhysX-enabled video games. Video games supporting hardware acceleration by PhysX can be accelerated by either a PhysX PPU or a CUDA-enabled GeForce GPU, thus offloading physics calculations from the CPU allowing it to perform other tasks faster, and as such, the whole system can provide a higher framerate, resulting in a smoother gaming experience."
Thank you Wikipedia
Basically, it does now, OBVIOUSLY not as well as any video card out there today but...beddo said:The PS3s GPU doesn't support PhysX hardware acceleration though does it?Strelok17 said:"PhysX is a proprietary realtime physics engine middleware SDK originally developed by Ageia (now NVIDIA) as the NovodeX SDK.

In which case it won't make much difference over Havok or another middleware solution.
We can hope good sir, we can hopeBrotherofwill said:Is this going to be kind of like when UT 3 got the physics expansion? If yes, then Hell's Yea!
If they brilliantly add the physics load to the GPU it will, and I'm certainly not buying a PPU for my PS3. Its also worth mentioning that most games just use Havok instead of PhysX because it already works on all the consoles.AceDiamond said:Remember how the first ports of games to the PS3 had horrible framerate issues and other odd glitches? Yeah for some reason I see adding PhysX will cause the same sort of situation.
What you said about RAM is exactly what I said, 256mb of VRAM. The GPU shouldn't be accessing system RAM while doing graphics or physics calculations. Also, if the Cell would be doing the processing with this new SDK, then what is the point? Currently the Cell is doing any physics calculations already. The GPU is still one of the weaker points in the PS3 hardware, I don't see the gain in adding to it's workload while the Cell is still not being fully utilized.Mazty said:Actually the Cell can do processes in tandem with the GPU unlike normal processors, so it will probably be doing the calculations.KSarty said:This isn't that great of an idea. The video card is one of the weakest areas of the PS3 hardware, it only has 256mb of VRAM. You'd be better off leaving the physics calculations to the enormous processing power of the Cell. Besides, PhysX isn't all that great anyways. Do you know why nVidia owns the PhysX brand now? Because nobody bothered to buy a PPU from Ageia because its a marginal increase in performance if any.
Plus the Ram in the PS3 is actually: 256MB XDR Main RAM @3.2GHz & 256MB GDDR3 VRAM @700MHz, so it's plenty fast enough.
Considering all Physx is now intergrated into the 200 series, plus now all to do with the code, rather than the physics accelerator:

Having used the Havoc engine in 3d software, the Physx engine is much, much more effiecent, giving great & ultra-realistic results with very little CPU demand.
Unfortunaly as Ageia now have their ass secured by Nvidia, it's harder to find the demo videos they had of games with/without it to compare, as they really showed the difference it makes.

Would be a good readStrelok17 said:NVIDIA recently released a developer kit for their PhysX physics technology for use on the PS3. This could bring powerful and smooth physics to several newer PS3 games and should allow smoother gameplay through better use of the hardware.![]()
