Update. Same laptop, same specs as in OP, once I realized that in closed environments with heavy lighting I'm going to see fps drops no matter what I just started turning on options. Current settings :
Antialiasing : Max
Anistropic Filtering : Max
Resolution : 1920/1080
Texture Quality : Ultra
Shadow Quality : Low
Shadow Distance : Medium
Decal Quality : Ultra
Lighting Quality : Medium
Godrays : Off
Depth of Field : Bokeh
Ambient Occlusion : Max
All options in View Distance : 50%
Distant Object Detail : Medium
Object Detail Fade : Medium
60fps steady most of the time, dips a bit in inclosed spaces to the mid 40's such as Vault 81 and some of those raider warehouses the Minutemen send you in on.
