Hi, I'm on a 3.2Ghz 6core AMD processor, 16Gb Ram, GTX 1050Ti vid card. Blender 2.91, via Steam ( so auto updates) usually works fine, so I'm suspicious of how i'm working.
The mesh was a curve, converted to mesh, cleaned of excess Verts and extruded. The cylinders (holes 6mm/8mm/10mm) are the default 32 sided, I've changed the dimensions and applied transforms. Difference boolean calls on the 'Holes colection' which has the cylinders in it. a couple of arrays spread out the cylinders/holes which display as wire.
it.. chuggs.. soo... slow..
is 32 sides on the cylinders considered excessive? should I get rid of the arrays and make instances of the cylinders? have i missed something obvious?
