I'm not sure if this is the game itself but I'm having unnecessary lag spikes in parts of my world that I didnt use to have lag in, with all my settings the same as they were.. Im not sure if it is optifine causing this or minecraft itself with the new update </3

it only happens in certain parts where i should be getting 100-200 fps, but they drop to as low as 60 in only certain parts. let me know please!
