Insane Lag!

I play a lot of ultra bullet and with lichess v1 my rating was happily around 1850 , after the grand update (v2) i struggle with getting it over 1700. In a lot of my games (ultrabullet) there is insane 3 second lags and my ping never gets lower than 80. PLs fix this lag issue ASAP

Disable tenths of second in the clock. Surprisingly, it causes a lot of lag in my system and I lost a lot of games because of that. Turning it off made a big difference. Disabling piece animations and every redundant interface element also helps. And enabling Zen mode too.
