Threadripper issues

@maru Do you have 3990x and 3970x machine on latest build Win 11 and latest bios/chipset drivers etc..to test these files?

Yes, we have machines with both CPU models. We would have to make sure that the BIOS and drivers are fully updated, but we can test on those machines.

HI.. I recently had the same inssue.. and Corona tell me, that there is some issue with the Corona render engine. Until this guys don´t change the Kernel ( or whatever), of the engine.. don´t buy machines with more than 32 cores. There isn´t work. In Vray it´s ok.. but corona doesn´t..
PLEASE CORONA RENDER.. make a corona 13 version, with performance adapted to AMD EPYC and Threadripper platforms.. with high cores machines..  PLEASE... don´t make more versions with sky´s.. we need performance...

There are multiple issues at play here, some of which are solved, some of which (despite ongoing work on them over the last 6 months) are not. You can bet that as soon as we can solve this, we will, as it's not through lack of testing, investigation, and trying solutions.

PS - Most single CPU high processor count issues should be resolved, if not all. The issues that remain are high core/thread count multiple CPU systems, in particular dual EPYCs.
