I've been playing around with the demo, trying to compare it to other renderers like keyshot and octane.

GPUs are meant to be much faster in rendering compared to CPUs.

But in the case of Visualize that hasn't been the case.

In a system with 2x Xeon x5650 and 4 x GTX 980Ti, I did a comparison render of the same scene in Visualize and Keyshot.

I realised that in a 5 min render the results in Visualize where actually worse.

That wasn't the case with octane. Octane which is a GPU only renderer was indeed way faster.

Is iray generally a much more resource dependent renderer?

Does Visualize not manage the resources properly and is that an issue that may be resolved in future releases?

Or are there any tweaks you can do in order to render faster?
