I frequently need to create a subset of a drawing by deleting areas and saving. The areas that need to be deleted are always different. LT2022 is MUCH slower doing this than LT2020.
Example, doing the exact same operation in the two programs.
Select an area with about 50,000 objects in LT 2020 takes about 2 seconds. Selecting the same area in LT 2022 takes 2 minutes and 17 seconds. The area contains mostly blocks containing polylines with quite a few arcs.
Windows 10 Pro version 1909, Intel I5 9500, 8 gig ram.
One difference I see between the two programs is that LT2022 will pop up a message "The high quality geometry setting has been temporarily disabled". 2020 doesn't do that. That setting change isn't a problem for me but may be a clue about what is happening?
