GPU preview

I hate Substance designer and would prefer Filter forge anytime for anything procedural. Love the features of Filter forge. Understand it much better. The whole FF looks like rare soft done by sane person with artist customer in mind and not a crazy programmer "flexible" invention.

But in fact I found myself using Substance Designer more and more every day. The only reason for that is nice realtime PBR preview with tessellation where I could see actual geometry displacement on a cube or any imported object. That turns height map creation almost into real sculpting. That along overweights so much SD crazy weirdness and makes you tolerate it.
Every time I come back to FF I feel myself almost blind folded with a slow unresponsive preview.

Another thing is the subgraph library. Copy/paste is cool but nowhere same useful
