Usually players always go for textures first, and while those are really important as well, I do those last. Probably the most important graphics mods that you can install. In vanilla Skyrim they are very low detail and the textures are badly optimized, so learning how to fix up the LODs will not only improve how the game looks, but actually net you even better performance depending on the settings that you use ( it frees up your vRAM).
If you don’t know, LODs are basically those small objects you see in the distance while playing. I’ll also skip all the LOD generation stuff because that deserves its own guide as well. However, if you do have a monster GPU and you’d like to try one of them, here’s my ENB guide. I’m not going to talk about ENBs because on Skyrim SE their performance is horrible. If you notice any broken links or discontinued mods, leave a comment! ENBs & LODs You just need to download appropriate mods between them. It’s the same for LE ( Legendary Edition).
