Physix PCI-E lanes?

[TheMorningStar]

How many lanes do you need for physx realisticly?

see i can run both my primary pci-e lanes at x16 and i believe i can then run both my secondary pci-e lanes at x1

is x1 any good?

The original Ageia cards ran on the old PCI bus... so ~266MB/s at best... an x1 PCI-e 1.0 port is rated for 250Mb/s and PCI-e 2.0 would double that... so probably useable.

Personally I'd say an x4 port pci-e 1.0+ would be better suited.

that was very much what i was thinking in comparison to the legacy pci bandwith but wasnt sure

I can't see Physx needing much bandwidth at all. A key difference between physics processing and graphics rendering is that physics is purely numerical whereas rendering needs texture files to be shunted around. It's the textures that eat up the bandwidth,

Same, implementation doesn't seem that complex so far, just bits of paper in Batman and some glass in Mirror's Edge

I'd imagine an old ISA bus would suffice....
