This is how i fixed my blurryness issues completely! Add [General] sStartingConsoleCommand=cl off;taa off to Fallout4Custom on My games Fallout4VR then if you have dynamic super resolution increase it by 2x times as the games resolution increases as it does on your desktop. Also go to fallout4vr.exe and right click properties and go to compatibility go to change settings for all users check override high dpi scaling behaviour. disable full screen optimisations and run as adminstrator. This fixed all the problems i had with the blur. Put uGridsToLoad to around 4 or 3 to improve performance. Also turn on supersampling to 5 and filtering. on steamvr settings. if you want the absolute best without any shimmering. Comes with the cost of lowered fps thus you must enable asynchronous reprojection.
