You need a longer FFT window to discern lower frequencies. Assuming a 44.1k sample rate and the default window size of 4096, you only get 10Hz buckets. Given that the low E is 82Hz, you effectively can't distinguish it from the D# at 78Hz and the F at 87Hz

FFT is configurable at the bottom of the page, but for me it gets unpleasantly laggy if I make it bigger than 4096

Yep, that's the tradeoff. As with seemingly everything else, you can thank Claude Shannon for that.
