I don't think there is a fix for that. Game runs smoothly at 4K/60fps and MSI AB says so in cutscenes too but they are choppy AF. Luckily there aren't many cutscenes of that kind so it's not a huge deal. I've done all side quests and almost all question marks and I'm so tired of this game. Luckily I've finished it and it was a great game indeed but I won't buy the DLC now. Maybe sometime in the future when it's on sale, we'll see. I'll play FPS and things that are far from open world games for now and a bit later I'll try to replay Witcher 3 from start to end.
