Most of the time I make sure to let everything load first, but finger can slip, I noticed it stutters if I do that. I have to find "unload textures" button, will be very helpful!
Only recently have I figured out (mostly) how to effectively play with morphs to get desired effect, so I have a few of those people of the past as well. I don't even do much with those looks after I'm done with the dress up, I just find the process super relaxing to unwind after work. I'm also only now coming to terms with the fact that my project to clear my "browse all scenes" of all look related scenes is futile, I acquire new ones at a rate much faster than I can handle. I would have to get my internet cut off for months or make this my full time job somehow to ever get there, but it's fine, I'm not going to run out of content to work with until 2.0 will be fully supported. I quess I will just fork some cash for another set of 32gb of ram, 64gb is not too much in my case.
