@Boldline said in Could locking a layer free up VS to only render and focus on active layers?:
it will essentially tell VS to see that selection as an image and not try to render and re-render the nodes each time I work on other parts of the file?
Yes.
Is there a time I should leave it off or turn it off at a given point?
It can be too slow if there are only a few vectors in the layer.
It works better for large number of (unchanged) vectors, gradients or image effects
Should I be adjusting anything with the "rendering thread"?
Let that unchecked, so it will use the current number of CPU cores on the system
