Ever since 1.19.40, the lag has been bonkers. A big issue I noticed was going through a nether portal, and there’s lag between my character being loaded in and I have died a few times trying to get into the nether that way. I cannot see what is happening and end up having issues. Another big one was in an ancient city, the Warden was mean to appear but did not, and after exiting the game and coming back, my character had died from the Wrden and had to respawn. Mobs, friendly and not, will lag while moving, causing issues that way. The world chunks do not load properly. Navigating inventory will sometimes lag a huge amount. There is just overall a lot of lag. I don’t know if it’s on other platforms, but I am playing on the switch when I am not on Java.
