Imbalanced mechanics can be charming.
Occasional bugs, even crashes, can be tolerated.
Missing content might not even be noticed.
Poor performance just fucking sucks. The entire time you’re playing, it’s a constant nagging problem. I make games on single-digit-megahertz systems, and even I obsess over smooth interaction. You can’t just release a game that chugs on god-tier PCs, even if it looks jawdropping… which this game does not. It’s nice! It’s not “40 FPS on a 4090” nice. Mostly you forgot to do LOD models, at all, in a game with a bird’s-eye view of an entire city.
Poor performance is the future of all big titles, so buckle up. They want to make games as quick as possible.
