Personally I'm not even using ENB, I'm using ReShade + SweetFX 2.0 and I've created my own preset (as converting any is a PITA) Super simple to setup, download the ReShade + SweetFX 2.0 pack on their main page, extract, run the setup, select fnv4gb.exe and dx9, done. At that point you just need to make a preset by editing SweetFX_settings.txt. Works just fine running fnv4gb through MO. Here is my settings in case you just want to see it working when you start it up. And some screenshots: https://a.1339.cf/ngnwhr.png https://a.1339.cf/chbcpc.png https://a.1339.cf/oxuedc.png https://a.1339.cf/arffti.png https://a.1339.cf/umuvzk.png As you can see I'm not going for heavy shadows (Would be overly dark with this mod set) or super fancy effects, I like clarity and performance myself. Do not try to install if you already have ENB, you would need to remove all ENB files first. ReShade seems to have depth buffer access in FNV so I might try getting a nice DoF going and possibly SSAO.
