Hi,
just a quick update, I am using a TR 2990wx (32cores, 64threads) and max 2020.3 on my workstation.
I did encounter the initialization lag with the previous versions of forest pack. Sometimes it took as long as 3-4 seconds.
FP just popped up a notification in max that there is a new update, 6.2.4, the release note says that the issue has been addressed by removing the tooltips.
I have to say I do notice some improvement in the initialization, but still not as quick as my old i7 4770k cpu (the TR is a dual cpu, 4770k is not, I understand).
Now, to complicate things even further:
- with the stock BIOS cpu settings the initialization used to be 3-4 seconds with my threadripper, using FP
- with overclocked settings, where boosting is disabled, keeping all cores at a constant frequency got me around 1,5-2 seconds for the FP initialization
- with FP 6.2.4 the lag is reduced even more, though I still need to wait around a bit for the initialization (empty scene, only 1 custom box geometry), I would say it is around 1,2-1,5 seconds now
- with the hyperthreading (SMT) disabled in the bios, and FP 6.2.4, I notice no difference in the initialization time of FP
The situation (first 2 bullet points) got me thinking that the problem might be with the TR cpu, and the slightly weaker per core performance compared to intel, as max only uses 2 of them at any time.
There is generally a bigger UI lag in Max 2020.3 with the TR cpu, sometimes the modifier list hangs for 2 seconds before rolling out the list, the render settings window takes abt. 3-4 seconds to open with vray (but not with corona), just to mention a few.
Now that I see that this is likely to be a bug in max's user interface, it has my hopes up again (to some extent).
The improvement is very welcome. Is there any chance iToo could get in touch with Autodesk to further address the issue?
High number of cores/dual cpu-s is definitely linked to the initialization time.
Thanks!
