it runs fine on my 4 core MacBook Pro from 2013 as well…sluggish viewport with volumes and I guess that's a gpu problem. Curious if the Vega GPUs are better than my current GTX650M…obviously CPU based operations will be at least twice as fast.
I have the 8 core i9 with Vega20. Houdini (and Nuke) runs very well. It heats up (i.e., the fans turn on and keep running) with almost any rendering job but sims, viewport, all very quick, responsive. I'll do some pyro, etc this week and see if volumes slow it down.
