For good measure and in the name of science, I fired up a UDIM series of six 8k tiles. Again, it runs fine up until I open an image editor where even just drawing a smiley face takes longer than it does for grass to grow. But I’ve come up with a work around so I can at least finish this project and then do some real digging to try and find a solution for next time. Interestingly though I’ve not had Blender crash on me at all lately ¯\_(ツ)_/¯
