Yeah, done all that. Latest version of everything and clicked both Reset Pure AND Reset to defaults and for some reason, those options make zero difference in game, when the first time I installed, I definitely seen changes in the curves when selecting the different ones, I preferred the flat curve.Make sure you're running the required pure anc csp versions, and reset pure to defaults
I'll try deleting and starting again with a fresh copy but I already overwrote once and tried and it seems to make no difference still. It's very odd. For sure I've done something else to cause it, the amount of options available are mind numbing. I've no doubt touched something.
