Bump. turning off the bending has improved drastically my performace i've got rtx3090 and great cpu and lots of RAM - so I'm glad I found this thread - hey developers on 13 - really think about whether this "checkbox" should even still be available in poser 13 preferences - i dunno - is it helpful for any situation nowadays? just my findings thanks for all the great work everyone merry christmas
