I usually have 50-60 FPS but whenever i go into a jungle biome, I get 1-10 FPS. This didn't start happening until recently. I have tried it with and without optifine, turning all my settings down, f3+a. Nothing works. Its all been on 1.16.2 (I could only put 1.16.3 as the tag but its 1.16.2). What do i do to fix this?
