This may be a bit off topic for this forum. I have a macpro with 12 cores and 24 total cores including virtual cores. Running Windows 8.1. VRay is currently just seeing just “12 cores.”
Funny thing is when I was using windows 7 VRay was seeing all 24 cores.
Task Manager sees just 12 cores. It sees one of the two sockets.
Device Manager sees all 24 cores.
I contacted Chaos Group and they were unable to pinpoint the issue.
Thanks for looking!
