Beautiful Lyrics extension (by SoCalifornican) laggy

Hey guys I need some help!! I've been using Beautiful Lyrics for a while and it is so great for immersion, it has been a great feature on album listening but a main problem using it is that its been really laggy sometimes, since it is so graphicy I wonder if I could make it use more of my GPU since I have a better GPU than a CPU and it keeps lagging even when i'm only using spotify with nothing open, or maybe some other idea that could optimize and increase performance for the app on my PC??? thanks a lot!!!

P.S.: I'm on Windows
