The community is already fixing issues with Nier Replicant's port

While the PC version of Nier Replicant may not be as disappointing as Nier Automata’s port, it still has some problems. As Julie Muncy said in her review, “The technical aspects are much improved over the original, which struggled to maintain 30 fps, but they’re not quite up to contemporary standards.” She experienced technical problems including “serious frame drops when I accidentally unplugged my controller, or a persistent issue where my mouse point kept reappearing on my screen during cutscenes, which was not great for the game’s sense of gravitas.”

Additionally, players with monitors that have refresh rates over 60hz are finding certain animations are tied to framerate, and when they exceed 60 fps the protagonist zips around so fast he’s tricky to control when precision becomes necessary. Meanwhile, other players are finding that thanks to poor GPU and CPU utilization they’re getting poor performance on PCs that should be able to run it much better.
