Dear Mojang, I have an issue that has started in snapshot 20w45a.

I never had this unplayable experience in my whole Minecraft history!

When I lode in the world it needs 5 min to properly start, but it does not work well

You will see on the two Images comparison with Optifine Mod & without Optifine.

I always had 45 fps on Default but now I have 12 fps, witch is unplayable!

I'm wondering if you will fix this in future and if you will can you tell my when!?

Thanks for now I'll notify you with more bugs soon!
