bad_uncle Thanks for using Ziva VFX
Your current machine sounds like a really good one.
Regarding the Threadripper 2 - I believe that our software should run on it.
As a caveat, our development and testing is performed on Intel, and we do leverage a number of Intel libraries (which may or may not be optimized for Intel specific hardware)
If you are able to run some test sims on the Threadripper before you purchase, that would be safest.
Let us know how you make out!
