Today I will deploy network rendering (32 core license) in my office.
Simultaneously my old machine will be replaced by a dual Xeon workstation with 16 physical cores.
If I enable hyper-threading, will KeyShot Network Rendering count 32 cores (16 physical + 16 virtual) for this machine?
This would make network rendering useless if I want to speed up a job that I send from my new workstation.
By disabling hyper-threading the total core count would be halved and that way I could add more machines as slaves.
Is rendering performance hampered (much) by disabling hyper-threading?

That's a good question ...
I was just reading http://nl.wikipedia.org/wiki/Hyper-threading (http://nl.wikipedia.org/wiki/Hyper-threading)
QuoteDe door Intel voorspelde prestatiewinst is ongeveer 30%.
So a single core with HTT, which shows as 2 threads, will only be 130%. While two cores without HTT will give 200%.
Question remains if KS sees a single core with HTT as 2 cores.
Keyshot does see HT as 2 cores.
How do you turn it off? That's something I hadn't considered. We are bumping the 160-core limit

HT can usually be toggled off in the system BIOS.

I just checked how my workstation (dual Xeon E5-2680) performs in KeyShot with and without HT.
without HT: 116fps
with HT: 156fps
That's a +25% drop in performance with HT toggled off!
