IR Best Practice

[dj_buckley]

What is best practice when using IR in terms of CPU?  Is it best to limit it to a set amount of cores in task manager?  I ask because I've just upgraded to 12 Update 1 and interactive is absolutely grinding my PC to halt, I'm only trying to preview a set of stairs and I can barely move anything around, and when I do there's instant lag.

I just unticked 2 of my cores and it becomes snappy(er) again

You can limit the #threads used for IR in Render Setup > System > System Settings without having to touch the Windows Task Manager.
Could you please also check if the UI/PC in general works better for you with the newest daily build? https://forum.corona-renderer.com/index.php?topic=43295.0

Maru - unfortunately not, I'm working in a live production environment on live jobs with tight deadlines.  I can't risk installing dailies and working with those.

Of course, I am not expecting anyone to use dailies for serious production work. But if you could sacrifice some time for just installing that daily, checking if the issue still occurs, and then reverting back to the release, that would be greatly appreciated.
Another option would be using multiloaders to start 3ds Max with a specific Corona version while having the stable release installed.
