Just thought I'd drop by and let you know that I have now succeeded in breaking the persistent limit even with Temporary=1
I am getting round it by deactivating two mods which add new worldspaces (Dreamborne Isle and Darkend). With them disabled I can generate DynDOLOD and play away to my heart's content. With them included in DynDOLOD the instant crash on new game is back. I wasn't intending this build to be another monster but, well, you know! I'm actually quite proud of my accomplishment
I must stress I am not posting because I am asking for any help with this, only because I figured you may be interested.
Both those mods add new worldspaces right? But they also must add a couple thngs to Tamriel, which is probably what puts it over the edge. I wonder if this still happens with Skyrim SE. I guess we will find soon enough (within a year) if that is the case.
