I've been looking for info on this, but everywhere I looked the answers were mixed. Does anyone know if using the console disables steam achievements?

I've seen a few people say it doesn't; possible that it depends on what console commands you end up using.

I've only used the FOV command and I still got Steam achievements after that.

I've used it to give myself a daedra heart, open a master lock, change my character's appearance mid-game and change FoV. Achievements still work fine.

I have used the console and still gotten achievements. I mostly use noclip, I try not to cheat. I also made an NPC essential.

Yeah, I raised carry weight to 9000 and changed the FOV, I'm still getting achievements.

I had a bugged quest and tried to put in a command to finish that quest. Turns out I accidentally put in the command that finishes all quests and their subsequent chains...and got 9 achievements. So, no, they do not have any bearing on steam achievements.

I'm using God Mode and I still get achievements
