This is a weird one. Somehow the cow posted my post as if it was Eric’s post.
(Come to think of it Eric and I have never been seen in the same room at the same time)
I wrote the following not Eric:
The problem on the Mac is bus bandwidth. Doing 4k io means double the bandwidth both ways. Enabling the optimize for sdi option could barely squeak out 4k with a 3xsomething beefy Cubix. I wouldn’t recommended it.
I also wouldn’t recommend trying to run heavy editorial and color on the same machine.
You’re talking about a box doing color work in 4k in real time. That’s pretty nuts, it’s at the edge of what’s possible with like a z820. There is a reason why shops doing 4K di’s overwhelmingly use Linux boxes.
