Hi, I need a help over threadipper 2990wx and corona.
I have a threadipper 2990wx cpu with asus prime x399 a motherboard+ RTX 2070 + GTX 1070 + 56 gb ram currently Installed.
What my problem is, Whenever I am rendering anything. Even a very simple scene with few objects and hdri. Corona and 3dsmax starts lagging like a lot. It gets impossible to work on it.
Here is a link to a video which I made (
https://www.dropbox.com/s/3xdnfopmk2qptwe/corona%20bug.mp4?dl=0)
So far, I have tried many solutions such as:
1)Limiting core usage on corona.
2) Installing corona 3/corona 4 and even corona 5 daily build.
3) Installing 3dsmax 2017, 2018, 2019 even 2020
As I go up on versions, the problem becomes worse. For only lagging to crashing whole 3dsmax scene.
As you can see in the video, the scene file is very basic. In task manager you can see...ram is not full....even graphics card using 1 to 2% usage. Everything seems to work normal.
I have Intel 6900k and AMD 1800x too and In that system, corona runs very smooth. Both are octa-core system. But in amd 2990wx, corona seems like it is not supporting the processor at all.
I have done corona, vray, Indigo render stress test. Everything stress test go flawless.
As far as I have tried debugging, I think this problem is related to corona not being able to handle the SMT of AMD. with that many cores, corona becomes unstable.(I do not know for sure)
I would appreciate any help on this issue.
