Razer BlackWidow Ultimate 2017 Keyboard Lightning getting laggy

Hi, After 3 month not in use, my keyboard's lightning effect is very laggy. And the lag happened when i used a profile downloaded from the internet, the based ones work fine. I deleted the old lightning profile and downloaded new ones but the lag still happened. There was no problem before then. I tried to reinstall razer synapse or reset Windows but nothing changed. Please help me. Thank you very much. Sorry for my bad English.
