How are you specs compared to the requirements? Particularly the RAM and GPU
I seem to remember a game (probably Deus Ex Mankind Divided) that I bought before upgrading my PC. I could play the beginning at 30 FPS lowest settings (maybe even reduced the resolution), but there was a cutscene that I simply could get past. I assumed it had something to do with how, up to that point, the map was small and manageable, and how I was reaching the more open parts of the game with simply too much stuff to remember/render
