I have spoken to some members of this forum. Most of them were not aware the fact, that since the last month, Ageia Physx acceleration card was replaced by Nvidia Geforce series :
Nvidia bought Ageia Feb., 2008. The Ageia Physx X1 chip had smaller computing capacity than a 8800GT, so Nvidia abadoned the separated chip based physics acceleration.
Now physics acceleration is done by the Geforce card universal computing unit (sorry, I do not recall its name properly) and much more powerful way that it was done by X1.
How does it related to NxOgre?
NxOgre uses Nvidia Physx library. If you use it and have GForce card and necesseary drivers installed, the calculation of physics is done by the GPU not the CPU. It yields better performance.
My program can be run only GForce card equipped machine only?
No. The physx driver can be instructed to use software acceleration, so your program can be run any machines. Of course, there is a big performance impact when using software only acceleration.
Is it supported by all GFroce card?
No. 8800GT and above is required. (For full list, check http://www.nvidia.com)
Where can I find more information/drivers about it?
Go to http://www.nvidia.com and look for the "Force within" part. Or jump right into it with this http://www.nvidia.com/content/forcewithin/us/index.html
What other advantages can I have?
- Stereoscopic vision (blue-red eyeglass, real 3d view, like in a iMax movie)
- 3 way SLI
- CUDA
Is anyone out there who can test for me?
If you want I can test your application for hardware acceleration. I use the following:
Asus A8N32-SLI motherboard
AMD 4200+ X2 CPU
2xAsus EN9800GT graphics card
1xAsus GTX280 graphics card (it is in the box at this moment)
4 GB RAM
Ogre 1.6RC1
NxOgre 1.0.22
Pack your project in a .zip (VS 2005 SP1 or VS 2008) or .exe with all .dll-s. Do not forget to add your FPS gadget on the overlay. PM to me before sending. I compile/run it on my box and make a screenshot of it with and without physx hardware acceleration.
Why is it good for me/others to have my project tested?
In this way we can test, how the hardware physx acceleration performs in Ogre environment.
