I actually kind of believe them. But not because the game was in great shape when it launched and everyone ignored it.
I played on release and it was rough. But I also played it recently and it was also extremely buggy even though people act as if the game was patched into perfection. Performance is still awful, although even at minimum the game looks amazing. Reflections in particular look "grainy" and awful unless you put Screen Space Reflections on Psycho or enable RT which murders performance.
On the other hand, the story is pretty good, the characters are outright fantastic and the secondary missions (that aren't just going somewhere and murdering everyone) are great.
Ever since Pascal, Gaming laptops have been acceptable. Before that mobile GPUs were abominations that performed horribly and got insanely hot. It's still a bummer that the CPU/GPU are soldered down.
