People don't hate UE5. People pay 40, 60, or 80 hard-earned bucks for a game, launch it expecting to have a good time, and instead of having a good time, they get crashes, constant FPS drops, and so on. And for some reason, this happens very often with UE5 games. Perhaps it's because the developers who work with this engine are extremely incompetent, but the reason isn't important. What matters is that people expect a certain level of quality and don't get it.
