Hey guys, I’ve been just doing a tutorial that uses a lot of Booleans (Josh & Ryuu’s awesome Sci-Fi crates) and when I am working in 2.91 it all gets really, really slow. I have zero performance impact in Blender 2.83 but those Booleans in 2.91 seem to kill my viewport frame rate. I included the file for you. Try for example to rotate the top lid of the crate around the x-axis or make the cutters collection visible and try editing one in edit mode.
Now I have a pretty beefy machine (AMD 9 3950 X, 2080ti, 64 GBs RAM) and it all works super smooth and without a hassle in 2.83, but 2.91 it just kills my perfomance. Anyone else experiencing the same? Its is 2.91 or some incompatible add-on I am using?
