i got 200-250 fps in unreal engine 5.3 but editor is lagging

i look task manager now. there is no significant change when i opened a content browser or etc. the 4.27 version just work fine. last night i tried the uninstall and reinstall but it didnt work. my laptop have mux switch. i switch it to run only the rtx 4060 and not with the intel xe. it work a little bit. now when i opened content browser or something i got 20-25 fps not 5-10. but its still unworkabile.
