I found that if I UNCHECK "External Perimeters first" I get a nice print quality even without "avoid crossing perimeters"
ymmv

Doing the inner perimeters first is always best IMO, so I keep that parameter unchecked. Apart from anything else, if you have any slight overhangs it gives the outer perimeter something to hang onto instead of being printed completely in the air. I see that it is how Cura always prints.

With Avoid Crossing Perimeters turned on:
Slic3r (x64) 1.0.0RC3 took 104.8 seconds to slice a fairly small part
Slic3r (x32) 0.9.10b took 12.9 seconds to slice the same part with exactly the same settings.

With Avoid Crossing Perimeters turned off, the results favored version 1.0:
Slic3r (x64) 1.0.0RC3 took 5.2 seconds to slice the same part
Slic3r (x32) 0.9.10b took 7.8 seconds to slice the same part with exactly the same settings.

Why is this??? I really want to avoid crossing perimeters, but I also really like other features of the latest version.]]> RetireeJay Ormerod Wed, 12 Mar 2014 21:05:25 -0400 https://reprap.org/forum/read.php?340,323157,323437#msg-323437 Re: Is it me or Slic3r are slow https://reprap.org/forum/read.php?340,323157,323437#msg-323437 antlvk Ormerod Tue, 11 Mar 2014 20:57:31 -0400 https://reprap.org/forum/read.php?340,323157,323162#msg-323162 Re: Is it me or Slic3r are slow https://reprap.org/forum/read.php?340,323157,323162#msg-323162 "avoid crossing perimeters" in slic3r?
