TheScorpion: Just like with the previous bundle, no overlay here too. Such a dissapointment
JL-maio1997: Yes, although DRM-free and bought the first remasters and now IV-VI, I bought it and have been playing them on steam. At least, the overlay works. I contacted GOG support and they confirmed that the game here does not have overlay support. Pitty.
I also feel like doing that, but I decided a long ago not to buy on Steam if there is the option in GOG or will likely come out here some day. I'll just wait and play without achievements.
What sucks the hardest is that is not that much of an overlay issue for me, I can live without the pop up notification just fine. The problem is that achievements are detected, but not displayed properly, sometimes they show up, most of the times they don't. Seems like a really simple issue to fix by GoG, they just don't bother
