did you increase your viewport mesh angle(initial would be 10)? you could also uncheck "Add details to inflections" and "Display hidden lines", which should definitely improve the overall handling.

Very nice! What are you using to print those?

Supagoat:
originally i have tried photopolymer, but the models are too light (0,5g)
now I use print to wax and lost-wax technology casting using brass.

photopolymer


wax prints





brass casts (the silver ones are from pakfong, just for testing)



coi:
to be honest, i didn't play with those settings, but will try, thanks for tip
