Physics... again...

post #1 of 4
Thread Starter 
So, this question may have been asked before, I even tried searching and couldn't find an answer.

I have a 680i motherboard, which has a PCIe slot for a physics card. Although I have looked over and over the web I can't find out when this is actually used and/or what it the slot does.

If i plug a spare 7600gt in this slot, will it automatically start working and computing physics in games, or is it something that has to be hard coded into games to see any difference? Maybe this is a feature in DX10 and not used in DX9? Is this slot useless for now?

And no, I'm not interested in aegeia or however you spell it.

It's for a future product that is not yet released.

Nvidia has not release any Quantum Effect drivers yet. I believe this is what they are now calling their physics solution and they have only said they WILL BE supporting it. They have not released much offical info. However, I believe it may need "Stream Processors" aka programmable shaders. Again, not sure yet.

Yes, the game must be written to support nVidia physics specifically. None are out now or anytime too soon.

www.nvidia.com/page/8800_faq.html
Q: What does unified shader core mean?
A: Historically, GPUs have had dedicated units for different types of operations in the rendering pipeline, such as vertex processing and pixel shading. With the unified architecture of the GeForce 8 Series, NVIDIA designed a single floating point shader core with multiple independent processors. Each of these independent processors is capable of handling any type of shading operation, including pixel shading, vertex shading, geometry shading, and physics shading. GeForce 8800 GPUs can dynamically allocate processing power depending on the workload of the application, providing unprecedented performance and efficiency.

Q: What is stream output?
A: Stream output is a new feature of DirectX 10 that allows data to be passed directly from either the vertex or geometry shader straight into frame buffer memory without having to pass through the entire rendering pipeline. The output can then be fed back through the pipeline to allow iterative processing and advanced shader effects such as particle systems and physics effects.

No, your 7600GT will not instantly become a physics processing unit (PPU)
