Man, I'm glad that people are enjoying the game as much as they say they are but I tried my first play through earlier this year and it was terrible. I saw almost no difference in the amount/type of glitches between what I experienced back in January and what I saw online when the game first released a few years ago.
I played on launch month and only encountered one bug that was game breaking and it was only a loading point glitch where I had to load to a previous save point. Played just a month ago and the whole game was super smooth.
I have 50+ hours and only minor graphic glitches. A couple dead bodies standing up, the odd piece of floating loot. Nothing that seriously detracts from the experience.
