Recently i have been trying with new grass mods and found out that Mod Organizer (i use the old one, cannot use the new one) can load multiple similar resources (e.g. grass) - sometimes resources use different names but occupy the same location, so MO cannot highlight duplicates in first place.
In game i've seen how grass changed from one to another type, depending on my view angle, e.g when turning around for 45 or more degrees.
Now, i do not know how this could apply to many other textures or meshes i use, because most of these are loose files. I am interested to reduce strain, so my machine keeps cooler, more silent and i am more relaxed to play
