Bad working and so bugs

First, the amount of RAM decreases a lot, but the game is played very slowly, then it slowly uses RAM until it reaches 2400 MB. When the hard drive is full, when it is full, the mine is very busy and has a lot of lag

Graphics card and CPU do not work at all, only RAM and hard drive

The bug is that sometimes a person's breath fills with water under his own and he does not suffocate

At 1.18 I was able to load up to 21 chancos, but not in this version

Because this issue is very annoying and after half an hour the mine starts to break temporarily for m

 

My system:i3 9100

Ram 8

Graphic card : 2x 710 

Ssd 120 + 500 7200 

Plss fix it in 1.19.2 optifine
