There has been a huge decrease in FPS in Minecraft Snapshot 20w22a.

My FPS in game is stuttering very badly a lot of the times and my FPS gets cut in half and can't even get to 200 FPS in the mines / caves.

Please fix this bug it will help a lot cause I have a hardcore world that I survived in for more then 200 days and a lot of times when I kill mobs at night or day and will lag so much I can die.

PC Specs- Ryzen 5 3550h with Nvidia GeForce GTX 1050 (3gb) 8gb RAM 5.9 Usable.

Minecraft Graphics- Fancy, 5x5 biome blending, 18 chunks, unlimited FPS, no clouds, mob shadows on, minimap levels 4, V sync off.

I know it's 18 chunks with 5.9GB of RAM but it worked great in all other versions of the game but this one. 

(The image is in 20w22a and I let the world load all of that but it still gets a lot of lag spickes that no other version gets 29 FPS is not always but it dips to that a lot)
