Never heard of that game, but I can definitely believe it, old games are where GOG really shines. But that doesn’t seem like a DRM thing, more like the game is abandoned on Steam but not on GOG, sometimes GOG patches some old games with their own runtime, curiously if that is the problem running the steam version on linux using proton (and especially proton-GE) is also very likely to work.
