I'm on v0.949b for Windows. I have a fairly mid-high end computer, but the game crashes if I try to play as a female character.
It also seems to crash sometimes if some mods are enabled. I had one crash pointing to a missing file from a mod called Clothes Extended - but after going through the directory, I saw that the file wasn't missing at all. The mod was perfectly installed. So it looks like the game is struggling to find some files for no clear reason.
