What hardware are you using?
I've been working my way through the beginner's learning flow and have been enjoying the exercises. The trouble is, my IT set up has not.
I'm running a Dell XPS-15 laptop with an NVIDIA GT 750M graphics card and it's pretty slow when rendering single frames - I've not got onto animations yet! Watching tutorials, others seem able to move around and edit scenes in viewport render mode with their systems responding quickly but I can't do that.
So I was wondering what equipment other people are using and how it performs for them. What I'd like to understand is the optimum mid-range set up which will cope with short animations and photorealistic scenes without becoming obsolete before it reaches the end!
(Just for info, I have set up Blender to streamline renders to the maximum extent (tiles sizes, restricted samples and light bounces etc) and I used GPU compute until I started getting CUDA errors but, to be honest, there didn't seem to be much difference between GPU and CPU.)
Anyway, I'd be interested in hearing other people's experiences.
Thanks in anticipation.
