So I did a first playthrough on 1.2, logged in about a 100 hours. A few very slight graphical glitches, but nothing really memorable. It was so glitch free that it was to the point where I was surprised about all the complaints. I'm playing on pretty old hardware at that, GTX 1060 at 1080p with everything maxed. I had a complete blast, it was one of the most fun gaming experiences I had in a long time.
I started a second playthrough right when 1.22 came out, I'm getting a lot of glitches and bugs. Whatever was done between 1.2 and now has been a step back in stability of the game. The problems still are pretty minor, not CTDs or anything, but it's becoming relatively common.
