Depending on your settings, things will either look too jagged and will distractingly shimmer and crawl as you move around, or else everything will look overly hazy and blurry, almost cartoonishly so. It's probably the first thing you'll notice about Fallout 4 once you enter the outside game world.

The first problem has to do with jagged edges and/or blurriness in the game. What I want to quickly cover here are a few methods to specifically address what I consider the major visual and performance problems with the game. Unfortunately, these days I no longer publish detailed game tweak guides (as explained here), but luckily there's a comprehensive Fallout 4 Guide which you can use to find out more about the game's settings and main tweaks. I've also been tweaking Bethesda's Gamebryo/Creation engine since Morrowind back in 2002, so I'm familiar with its many quirks. I really enjoyed Fallout 3, so now that I've finally started playing Fallout 4, I'm happy enough with the fact that it seems to be more of the same, with upgraded graphics.
