My fault, have overlooked that SRO is already optimized. But the Vano89 pack is still confusing me somehow, since I already optimized the HRDLC 1~3 as said in the SRLE Guide (1k Normal Maps), there shouldnt be any real difference on the VRAM load, but after making a 3 Profile in MO just for testing purpose I was getting different VRAM numbers.For Example, my Skyrim with SKSE, Cleaned Vanilla ESMs and the Optimized Folders (Textures, Dawnguard, HRDLC1 etc etc) in the New Game Opening scene was giving me a max VRAM load of ~1010, with the Vano89 pack installed last (so it overwrites files in the HRDLC) I was getting a max VRAM load of ~950, for Vano89's Pack I was using this Option "Hybrid (1024+2048) + Hi-Res Secondary Stuff", so a small amount less VRAM use then before, so I was thinking that there are eventually some conflicts, that Vanos pack overwrites wrong files that are needed for SRLE maybe?
