why Booleans slow my computer more than expected 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?
Blender 2.91 comes with a new &quot;exact&quot; solver for Booleans. The old one is still around but by default EXACT it enabled.
There's the option &quot;fast&quot; in the Boolean Modifier (this enables the old algorithm/solver). If you click it you get way better performance but a less accurate boolean operation.
