Since version 1.21.5 there has been an optimization error. In version 1.21.4 I could easily reach 200 fps, but when I switched to 1.21.5 my fps was only 50-120 fps Even dropped to 0 fps for about 1 second continuously , 1.21.8 was a huge disappointment, I dropped to 2 chunks and got 45fps, do you guys really want me to play minecraft and occasionally look up at the sky to increase fps?
