It renders the game absolutely unplayable, considering that most of the game does require timely movements and reactions, especially with all the hostilities that have been added into the game with the Pillager and Illager update, every 45s-2:15m the 2-3s latency comes into effect, and is especially noticeable and devastatingly frustrating when I am getting chased by mobs, and not only does the game just make me stand there and idle, with the only inputs being recorded and processed being the right analog stick (for camera position), the rest of the game is still processing the enemies attacking me and killing me before the 2-3s finish. Even with shields. Even with potions. Even bought a SERVER so I could PLAY with people to help give me the edge back and it behaves 1:1, copy+paste, EXACTLY how it behaves offline (in relevance to the 2-3s latency occurrences). 

Reducing the in-game graphics to the absolute lowest settings increases the occurrences of the severe latency ((chunks/particle rendering) which, makes sense in a weird way, it has to load more instances, more regularly since the rendering is reduced, and if you're moving very quickly via train/swimming/sprinting you will reach those processing points much faster than expected)

TL;DR

Why offer the switch users an option to alter the graphics and rendering settings if the versions you're releasing literally have less than a 5% beneficial effect on the actual game itself? 

It's been like this since February 5th of 2019, I've bought myself a copy, my family, my friends BEFORE this was an issue and now I had purchased your Realm Service and it is still just absolutely

without a doubt

unplayable.

Please, I beg of you Mojang Lordes, please resolve this issue, I'm really trying my best to enjoy your product. Buying a product that works isn't unreasonable, is it? 

(Also, I feel it is worthwhile to note that the 2nd generation iPad runs Minecraft considerably better than the Nintendo Switch Version.)
