Scaling resources - how many CPUs?

[Patryk Kizny]

Hey,

I wonder how does MB3d scale on a decent rendering machine?
In context of Windows 7/10
- How is hyperthreading supported?
- What is the maximum number of CPUs that can be used (theoretically and practically)? And I am thinking big here - up to 72 core per machine.
- are there any plans to use OpenCL or GPU architecture?

Thanks!
