Thanks, Morten. I really think that most professionals would spend $400-$500 to double there render times.
I'm guessing you mean to halve their render times?

In any case, having 2 or more GPUs at your disposal will not necessarily improve performance by a factor of 2 (or more) in 3D applications. Last time I checked most CAD applications did not benefit from multi-GPU setups (although this may have changed since then).

Performance will ultimately depend on how each application/game has been programmed to take advantage of multiple GPUs. Here's an example from a well-known 3D benchmark application which does take advantage of that:

Remko actually followed the official guidelines for implementing multi-GPU support when they developed Lumion, but for some reason performance with a multi-GPU setup is not significantly better.

Thanks, Morten! I meant to say double the speed of our render times!  :-D

You are right... Some renderers out there right now are getting linear scaling... Drop another card in = 1/2 the render time. Drop 3 additional cards in, you are now rendering 3X faster.

I apologize for not knowing this - does Lumion take advantage of a GTX 690, dual chip card?

Thanks,
Brian

Well, it will render just fine, but don't expect significantly faster render times (this goes for any multi-GPU setup in Lumion, whether it's a dual-GPU card or several cards in SLI configuration).

Remko knows more about this topic though, so I better stop here :)
