No. Only fluids require hardware.

@ Bozzy
If the AGEIA-SDK 2.6.2 Version gets implemented/converted into DP (=Dark-Physics) completely, fluids in "softwaremode" may also be possible in future updates of DP!

Untill now, try to keep the amount of objects balanced in your program and it should work fine for everyone you give it to!

Only thing you and the people you give your program to NEED is the actual driver from AGEIA-Website:
http://www.ageia.com/drivers/drivers.html

My game works fine with the "6.10.25" Version!


Good luck and have fun with PhysX!

Why are you guys trying to take the card of the equation, what bad it does for you guys to suport the PPU? Remenber Ageia only win if you guys support the hardware. If you want to make a game with the Ageia PhysX SDK (darkPhysics) the lest you can do is make it use the PPU for more advanced effects and help the guys that made this nice physics API.

@ Argoon

You are right in that point! (My DP-Software-Mode-Compo Entry had this option, BUT in fact I was unable to test it, it seemed not to work properly!)

I actually would buy one, IF there was a PCI-E-Version out there (which was announced to be released in october, but seems to be put further away in to next year!)

Do you have a PPU-Card?

If so you may want to try my game (NOT the downloadable Version from the newslatter), use the link from my sig (then follow the instructions on the website of rapidshare.com)!

I tried to download your game but declined to go through the "Rapid Share" system. Why not make it available through the forum's built in download system?

With regards to the PPU I have purchased and returned the BFG card and then purchased the ASUS card. I have noticed almost no benefit to using the hardware. From my previous forum discussions I am told that you need a very high end system preferably dual SLI graphics cards and the latest CPU to realize significant improvement benefit from the PPU. In part I purchased the card to support ageia and there fantastic software but my intent was to use the hardware to demonstrate some real world physics concepts for my profession. If ageia's business model is in error I’m sure the later releases will include a charge for the driver’s rather than go out of business.

Yes Hoozer i have a PPU and i would love to try your demo to help in the hardware tests.

Codger i only can talk about my on experience with the card, i have the Asus one and to tell you the truth i can´t see any diference on the darkPhysics demos but on the demos posted by Ageia and the games that support it i can realy see a diference is not something of a nother world but is a begining of something. About the PC requirements the SLI is not necessery (but helps) i have a x1900 XT and i can play GRAWF on 1280x1024 everything on high and have a smoth gameplay. The CPU requirement with the card only is not very high but that depends on the game so it is truth that you need a good PC to use the PPU but that is because as you know games are now graficaly more complex and demanding on the hardware worse thing will apen with the Nvidia and ATI(AMD) solutions you will need a expensive and top of the line card (8000 series and R600 series) to have a litle more effects (effectPhysics) on your game.

Hoozer i tryed your demo and it game error a and crashed, my setting 52 objects, paralax-mapping on, reflection on, time something C, hardware on. The error is in the attachment.

@ Argoon:

Thanks for giving it a try!

I really can't tell exactly what it is! (I used the following to initialize the card in Hardware-Mode


Where the help says:
phy start:
1st parameter: Soft-/Hardware-Mode selection (1= hardware)
2nd para: 0 = rigid-body-scene
3rd para: 1 = enable mutlithreading
phy set timing:
1st para: maxTimeStep#
2nd para: maxIterations
3rd para: method (0 = fixed time steps; 1 = variable)

I also used a 3Ds-object (the bar with angled sides):

I suppose that this object/dynamic-mesh is causing the bug somehow!

Did you tried it in Software-Mode?
The first thing you get asked isn't the "number of boxes", it's the box-size!!! The bigger the value the less boxes are there! Have a look into the "...MANUAL.txt" and you see under part "4. Configuration-Options on StartUp", "The 1st Question" a list that shows some of the box-sizes and in what box-numbers it results!

(I made a small update V. 1.2: now it uses a box instead of a mesh!
Maybe the bug is "solved" now! By pressing "b" you can load the new bar that caused the problem! When you load it, the game should crash as before! )


Thanks for the experiment!

No problem

Yes i tried it in software mode with the same options and it worked.

p.s - when i wrote this your new 1.2 demo was not uploaded on rapidshare so i was unable to test it.

cheers

@ Argoon:

Maybe you can give my new version 1.2 a try ad see if the "MeshError" is still there or solved!

If it works, you may can tell me, if there is a difference between Sw- and Hw-Mode!
(Remember higher number = less objects:
Examples: Box-Size: Amount-of-Boxes:
20 36
15 120
10 378
5 3240
4 6270
)


Thanks for the help!

Ok i tested your game here is the hardware results.

Tests:

4+Y+Y+Y+C+Hardware= crash ( Body::setActive:limit of 4000 active bodies reached! Body activation is denied.


5+Y+Y+Y+C+Hardware= crash (generic windows error (progame hade a error and needs to shutdown...)).

10+Y+Y+Y+C+Hardware= Run (bad performance(slow smoke and flag) the ball don´t move)

15+Y+Y+Y+C+Hardware= Run ( visualy the smoke is more fast but the ball still don´t move)

20+Y+Y+Y+C+Hardware= Run

Hope this helps.

Cheers

@ Argoon:

Thanks a lot! Seems like the "Hardware-Mode" is less performing than the "Software-Mode"! (I hope this changes with the following DP-Update!)

Cause in Sw-Mode I was able to run it with box-size of "4", although the FPS was only between 1-3!

I must admit, that any further bug killing would only be possible, if I had a PhysX-Card for my own, because there are just too many possibilities to tamper with!


Thanks once more for helping me with this!

No problem i´m glad i helped. Now about a PPU for you, it seams that Ageia has dropped the price on the card and give 3 games with it, is a good time to think in buying one. ( That if you don´t want to wait for the GPU´s makers solutions.)

@ Argoon:
I saw the new AGEIA-offer, but I would prefer the PCI-Express-Version of such a card! (Such a thing was announced a while ago, but it seems that it was put aside for some later release, who knows!)

I made a thread in the "Programm Announcements"-Section, because this was a bit off-topic in this thread!

http://forum.thegamecreators.com/?m=forum_view&t=93582&b=5

You got a credit in my "MANUAL-file" for finding the Hardware-Bug! (Or should I say for testing it first on hardware and giving me feedback!)
