Telling SE to stop using ram at a certain threshold wont work. I set RamSizeMax to 4096 because my graphics card stops working at almost 4 gb of usage. On my machine, this is what happens when I try to turn on detail textures. Dell Inspiron 5547, Intel HD 4400.
(Posting the following two at least for posterity)
Also, the custom atmosphere models imported from 0.980 do not show up.
As expected, imported custom shader mods also dont work
