since i started playing this new snapshot i have a huge framedrop from 70 fps to 12 fps idk why this happened and when i got back to 1.15 and older snapshot the framerate was 30 instead of 70 after this 30 fps kept happening untill 1.12 then i had my regular fps again 

note setting graphics lower doesn't effect the framerate

another note: sometimes it doesnt happen but after a while it happens again

i think this has something to do with the new modsthingy cause when i emtyed the mod file the fps whent to 12 till 25 and from 30 till 48
