So on Steam they've updated the game and released all the DLCs and whatnot, and it's broken the main game and PotFF. To the devs credit, they've fixed some of the bugs, but not all. Whether it's annoying buzzing sounds that won't go away or giant jagged polygons cutting through the enviroments, it's just an overall worse experience than pre-updates.

What I want to know is, is the GOG version affected by all that too? All I have with GOG is the regular Epic edition (thanks to their awesome Connect service)--no Call of the Tenebrae, no Echoes of the Dark Past. Will my game still be affected by all the bugs, or will it be the same pre-2017 experience I'm looking for?
