Title: CUDA and GPU rendering
Post by: eon_designs on February 08, 2013, 08:16:52 PM
I would love to see the addition of either CUDA or GPU support so that rendering was done via the graphics card and not the CPU. This should speed up rendering times.

Currently use some video encoding software that utilises CUDA, the difference is incredible. Without I get around 50-60fps rendering/encoding. With CUDA this increases to over 300fps. Would be excellent if Keyshot could benefit from this increased fps?

Thanks. Eon.

If you want to speed up, why not use network rendering?
That will still be more flexible than a networked GPU cluster, where all GPU's will have to be identical for optimal performance.

I think I may quote KS-guys on this ... "GPU rendering in KS .. Ain't never gonna happen"  :-X  ;)

It is not that we do not want to use GPUs. The algorithms that make KeyShot fast do not map well to GPUs. We have made a GPU implementation internally, but it was too limited and it only ran on certain types of graphics cards. Intel will release a new generation of CPUs later this year with a significant increase in the number of cores - this should translate directly into a performance gain for everyone.

Henrik, are you referring to Xeon Phi architecture?

Not necessarily. There are other chip sets in the works.
