NVIDIA's PhysX: Performance and Status Report - Part 2

[Rob Williams]

The time is almost here... NVIDIA will be unleashing the new drivers to enable PhysX support on all 8, 9 and GTX-series of GPUs. We've taken a hard look at the new driver, and also the new techdemos that are part of NVIDIA's new 'PhysX Pack #1'.

It took a little longer than expected, but NVIDIA is soon to unveil new drivers that will open up PhysX support on all 8, 9 and GTX-series of GPUs. We've decided to follow-up on our previous article and see where PhysX stands today, and also pit seven GPUs against the new drivers.

Read the article, then discuss it!

Very exciting stuff

I would like to know how SLI may affect performance? Any thoughts?

Because of the time-constraints on this article (the entire article was completed in ~13 hours), I was only able to tackle so much. I didn't have an SLI-capable motherboard hooked up in order to conduct that kind of testing, but there will be such testing in the third article, without question.

Re: SLI - (from my memory of CUDA documentation) CUDA is essentially unaffected by SLI. That is, when SLI is active, CUDA sees only one device. If it isn't active, it sees two, and can thus use double its ability to compute - SLI is a very low-level fake-out, I recall reading. I'm guessing turning SLI on and off will have non-trivial effects on this PhysX stuff.
