Quadro 4000 Alterantive for 3DS Max 2013

[Zdravko Barisic]

Thanks Dimitris,

So, I install 2 drivers, quadro and GTX, one after other.

Choose display for Quadro, and pick up both or one card for CUDA apps?

Thanks, again...

What Andrew was saying - and is easy to figure out yourself - is that once a GPU starts computing a progressive rendering, if at the same time it tries to feed the viewports, the latter task will suffer. Viewports become very slow.

 

Remember, that progressive renderers are still not as fully featured as the CPU versions, so the most useful workflow for most people I know, is to use them in activeshade windows, testing cameras, lighting and shader changes within the scene (with HDRIs, proxies etc), getting a complete picture before switching to the CPU engine for the production of the final image(s).

This is hard to happen when the card is torn between modeling viewports and activeshade cameras.

Thus, you can use 2 or more separate cards, one of which will be dedicated to the viewport - could be a Quadro, Radeon or whatever - and the rest being used exclusively as GPGPU cards. For the latter, high memory, fast GTX cards are the natural choice.

 

If the RT engine satisfies you enough to be used for final images and/or animation sequences (massive time savings), then ofcourse you can switch even the primary "display" card through the VRay RT settings, to also work as a GPGPU card for progressive renderings, assisting your auxiliary GTXs for even faster results (talking nVidia here, as VRay RT is badly implemented for OpenCL in combination with AMD cards).
