Definitely would have given more stars but after each update the performance optimization has gotten worse. When I originally downloaded this I easily played it with medium 30 fps, then after an update I had to lower some settings and now even at the lowest settings I can't hit 30 fps, during some fights it lags and drops too much and at certain places while moving around the camera, I hope mihoyo fixes this soon as such complaints can be found everywhere from reddit threads to youtube comments.
