Had major lag and stutter with my powerful computer (not showing off)
happens randomly it feels like the fps drops to 1 for around a second then goes back to normal, turniong off hairworks seemed to help but problem was still there.

Found out it was the Gog overlay, I know it used to cause stutter and lag in games but thought that had been fixed, just a heads up for anyone having the same issue. Annoying though as I like the Trophies popping up etc.

Hmm. Just clicked on this thread by impulse. I was ABOUT to start a new thread about achievements. Trophies popping up? So.. GOG DOES have achievements?

Not all. Only certain games whose developers are still actively supporting said game and deem to include them.

You can check which games support them on the game page in the store. It’s on the right side below the game details.

What about Witcher 3. Surely it has achievements on CDPR's own platform?

Yes, it have.
