based on the number of people commenting here that achievements aren't working, it may just be that that's the percentage of GoG owners whose achievements ARE working.

I've only had this issue with one other game on GoG and it's another "indie" game (Dex, for those curious) so maybe the GoG playerbase just isn't big enough for some of the smaller games to get stuff like that fixed

My achievements are also completely borked. Only tracking play time.

Clocked in about 11 hours, no achievements.

13 hours into the game -- and I also have no achievements showing up.

Also -- all my save files are timestamped (in the game menu, not on my hard disk) as four hours earlier than my actual clock time (which is EDT).

Had confirmation from one of the developers that during development the local GOG achievements were working, which means that it is very likely to be a GOG related problem. Who knows if or when they will fix this.

Not sure what the cause is, but if one completes the game and has zero achievements, that's a sign that something's off, right? Playing through GOG Galaxy.

I beat the game three times, the last time on maximum difficulty (3/3/3/3). I'm still at 0% achievement. Between each run, I reinstalled the game to test if that would work, and it didn't.

I thought this as well but, I have Cyberpunk 2077 installed on my D: drive and GoG is on my C: drive and the achievements are working fine there. Sadly the whole GoG system has not worked properly since I have been using it, from stuff like this to the never ending battle some have with the app never wanting to update correctly or the amount of stuff you have to redo anytime you may have to re-install it etc etc. In the end though, I just deal with it cause there is something comforting in knowing that I can actually have a copy of the game I buy here instead of it feeling like a long term rental...cough cough (extremely heated water vapor) cough cough ..ahem

Did you notice an increase in the number of encounters and higher damage when using combat setting 3? About 2 hours in on this setting and I don't think it's working for me, I'm not seeing an increase in encounters and the damage seems to be the same as the other 2 settings. I'm wondering if any of the 1 or 3 settings are working at all cause if you use the lower mission setting you don't get waypoints either.

I guess I didn't lose anything by playing Gollum first lol.

Well, the game has been updated, I finally got my first achievement, but it still doesn't work...
For example, I found a new secret door, but the achievement still doesn't appear.

Got my first two achievements as well for completing the objectives in Flight Deck, 27hrs into my first ever play through.

Sometimes GOG disconnects, and refuses to reconnect. I think that may impact earning achievements, so ensure the galaxy client is online. I've yet to see a pop-up inside the game when earning achievements, have to check it once in a while.

Yesterday I started a new game and unlocked the first achievement.
Only a quick test, but maybe the latest patch fixed the issue?
