since the java 16 update is released the fps is terrible even when I put the render distance on 2 chunks the fps is still bad.
before java 16 I was playing with 70 to 150 fps but now I'm playing with just 2 to 20 fps
Update: after the 1.17 pre release the fps got better but not as good as before now I'm playing with 15 to 40 FPS and when I enter a cave my FPS goes to 25 to 60 FPS.

@Nate Johnson, I agree that the absolute FPS by itself doesn't indicate a problem, but the OP is telling us about a drastic decrease in FPS.
Just out of curiosity, is your framerate also bad with Java 16 in 21w18a and earlier? (If it is, then we know that the problem is with the migration to Java 16 and not something specific in snapshot 21w19a and later.)
edit: I originally wrote 20w18a/20w19a instead of 21w18a/21w19a

Yeah, It is from 21w18a
Β edit: but the 21w18a did not have java 16 but the fps is still bad in it but with 21w17a, 21w16a, etc the game was running good
