I am not utilizing the full official HRDLC because I only have 1 GB VRAM, so I am using these mods as recommended (mentioned in STEP's "Skyrim Installation Guide"): "Hybrid (1024 + 2048) + Vanilla NormalMaps: Select "Core files" (selected by default), "Hi-Res Secondary stuff", and "Hybrid + Vanilla NM files". Also install the "Compatible Version" optional." However, I didn't see whether I leave these mods as separate from STEP:Core or include them in it. Do I activate them before starting my STEP:Core installations of mods? Any kind of clarification would help and would be much appreciated!
