Not using all CPU Core

Hi,

 

since the last update of Windows 10 to V2004 this OS is using all CPU sockets. I have 4 Xeon CPUs and 40 core with HT, means 80 logical CPUs.

 

While all other 3D Apps now use all CPU power, DAZ is still using just the half of all the CPUs available when rendering. Is there a trick I missed?

    I think Win10 limits the number of threads, just to be mean. A system like that deserves Blender on Linux.

    Well since V2004 of Win10 all CPU sockets are supported. Blender works fine now with 4 sockets, just DAZ not :(

    I ran into the same thing when I tried to benchmark a dual socket Epyc. I think DS chokes on NUMA but others report it worked fine on 1st gen TR so I still am not sure.

    Well, I have to correct myself. the 4 sockets just worked till the next reboot. Since than just 2 sockets again. M$ wants to sell the Pro W version I guess. However, since the reboot DAZ isnt working anymore. Tried to pull back the upgrade, no results either. So DAZ quits after start, showing the interface for a few seconds and than crashes. Couldnt find anything in the logfiles to solve the mistery. Will upgrade to 2010 Pro W shortly.

    You're trying to run a quad socket Xeon rig on Win 10 home?

    What is showing at the bottom of your Advanced tab in render settings?
