Lagging while beating the Simulacra (Wuthering Waves)

Hi if you're reading this thank you! I will be making videos here and there I am playing daily if you got any questions post some below I'm still testing out the game as it goes I'm a casual free to play player and plan to remain so until the end of it!
Might make some guides but it will likely be a mix of commentary and some game play perhaps some ideas on how to clear some stuff and criticism of course cause I don't believe it'd be honest otherwise.
Uploading this lag fest cause I thought it'd be interesting to showcase how sometimes I have to fight stuff you can skim and skip around if you wanna figured out a way to lag less now while fighting but sometimes it may still lag tldr for me its alt + enter while reducing the size of my screen before hand. Don't know what causes this but this wasn't gonna that much of a daily video/normal one. Uploaded it let me know how y'all are doing this is just some extra video I wasn't sure let me know how it has been for you guys!
