Corona doesn't play well with 5960x

[casinowilhelm]

Hi, I basically can't use corona without disabling at least one thread, preferably 2. It will completely take over my machine for upwards of 15 minutes which is incredibly frustrating. Or, even when cores are disabled, it will still sometimes just completely freak out max, making it unresponsive with windows flickering on and off, opening and closing, going white etc. This mostly resolves itself eventually but sometimes requires me to force quit max from the task manager.

It's really annoying considering how much time I save generally using corona, to have all the benefits wiped out by 20-30 mins of my machine going insane every day because I forgot to reduce the number of threads it uses, or it does the crazy window thing. Any ideas?

my setup:
windows 7
max 2015
latest corona
5960x, 64gb ram, gtx 980ti

I have two ideas:

1. Can you start 3ds, then load Corona, render anything (even empty scene), go to task manager, and see if you are able to change affinity?
2. Without overriding the number of threads (leaving everything at defaults - so that it would get laggy) - go to task manager and manually change 3dsmax.exe process priority to low. Does it change anything?

[casinowilhelm]

Yes, I can change affinity. That's normally the only way I can recover control of my pc, by very very slowly chugging my way into task manager (that's what can sometimes take well over 10 mins) and removing some cores that way.

I'll test the priority thing over the next few days. Means I have to remember to use it every time I start max, of course...

Does nobody else get this?

Yes, we have received few similar reports, but we are not sure what is causing this and how to fix it.

@Maru: are these reports only related to this CPU or are other cpu-models affected as well?
thanks

We have this since ever in a startup script:

Code: [Select]

sysinfo.maxpriority = #low;
Just put this into a textfile, name it for example "priority.ms" and save it in your scripts\startup folder.

Ideally all your nodes share a common startup script folder so you can do it for every node/workstation at once. This can be configured in "Customize"->"Configure System Paths"->"Additional Startup Scripts".  Point this path to a shared server path and directory where all your machines have access to (using UNC notation) and home your shared startup script(s) there.

That setting gets saved in 3dsmax.ini so you may copy 3dsmax.ini over or do it manually for every node or change it remotely with the use of some text editor in 3dsmax.ini.

Good Luck!

have you tried the latest daily? we did some improvements on scheduling priority lately...
