Hello,
just a short question regarding the 2012 Version.
Is it still recommended to turn Hyper-Threading off for the best performance?

YES.
2012 and previous versions are enhanced by multi-thread tech, which has better performance with Hyper-threading off.
PS:
Do you have any benchmark data for Hyper-threading on and off?
Thanks.
Me? No sorry.
I was just asking if it may be a good idea to switch HT on, because in the "new features" an improved multi core support was announced.
Anyway - thank you for the quick response.

It is still typically best to turn off hyper-threading with any compute intensive application such as Adsk Sim Mech. While I have seen a couple of benchmarks that showed improvement, in most cases, the analysis takes longer. The cases where HT actually helped were small MES models that had many, many time-steps.
Plus every release we are adding additional multi-core support.
I, too, recommend turning HT off.
In your BIOS setting.
There should be a tree "advanced settings" or something similar.
You find the settings when you pres "del" or "F8" during the boot screen, depending on the manufacurer.
I happend to have a simple 2012 benchmark about HT on/off.
HT on is around 40% slower than HT off.
My system is win7 64bit with Intel i7 12 cores (24 after HT on).
