It can be because you have under 100gb storage, you should have 100gb to have no lag, for me that works, it prolly wont work if you dont have atleast around 200gb on your laptop/pc
Bro i really feel sad for you 😢😢😢 You really have to buy new pc or laptop, but do you know what? Go buy an gaming laptop nitro 5 because its the best one ever
