My machine is Win10 64bit, AMD Threadripper PRO 3955WX, 256GB RAM, 2*RTX 4090 + RTX 3090, NVMe 1GB drive.

As for GUI slownnes, when GUI export popup window show up and then i try do drag slider it's sluggish, even typing the value is so slow that here is 15-20 sec pause between going to next input field.
I know it's because of big model but yeah that's why i hoped there could be "delayed" update button or so for those cases.
When model is not so big it's fine, GUI is responsive in those situations..
