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
