Whenever I get in about a 30-50 block radius of a village, my computer starts running the game at a smooth and crisp 1 fps. When I go in F3 everything looks normal, the only thing weird is that my FPS drops stupidly low

I play on Fabric for version 1.21

Can you send your output log? Also, do you have any other mods and/or data packs installed? You also need to specify which version you're using, there's a bunch of alpha builds for 1.21
