I went through my shots of Janice looking for the nicer ones. Here are a few. This post may contain spoilers, YMMV. I run my game in full 1080p, and I've only started to see slowdowns now that I have 2 & 4k textures all over the place.
This shot is from the second day out of the vault. It is one of the few that I have of her with her old eye makeup. She was yakking with Codsworth deciding whether or not to take him along.
This next shot is of her in Concord, right before she goes up on the roof for the power armor.
A little bit later, she went up to the bridge deck to the east of the dish at Olivia and came back down with a nice .308 sniper rifle. The raider donated not only the rifle, but his life as well. This is in Sanctuary after the Minutemen set up shop. Janice was having one of her many chats with Preston.
It was about here that I got her down to Fenway. That first trip was a bitch, and it took awhile. I had to go back and forth between points mebbe a dozen times before I actually made it into Boston proper. Set up a settlement or two, dispatch the raiders in Corvega, and picking up junk as I went. Haul back home to Sanctuary, rinse , repeat. This was also right around the time that v2.1 of Commonwealth Cuts came out. I had been adding mods all the time, and I think I was about up to 50 or so at this point.
One of the mods I downloaded allowed me to put legendaries on weapons, clothes & armor on the crafting bench. From that point on, most of her stuff has been buffed out with either boosts to CHR, or STR. I generally put the STR on armor pieces.
