  • Details: Since the December update, the game performance has become significantly worse compared to the previous (October) version.
    I am not using smart Zoi, but Zois’ animations still often feel like they are in slow motion, and the FPS frequently drops to single digits. In previous versions, the game could run normally with the resolution scale set to 80%. For smoother performance, I usually set it between 50–60%. However, in the current version, even lowering the resolution scale to 30% still results in severe lag and poor performance. This issue did not occur in the version before the update. I hope performance optimization can be improved in future patches.
