Ever since direwolfs pack got updated at 3.1, I've been having crazy lag. I went from 140~ FPS to now barley 50, with frame drops to 20 or 30 every few miliseconds the entire time. I loaded up another mod pack and it plays pretty good at around 100 and normal minecraft 1.16.5 plays at 180. I'm not sure whats going on but it's really hard to play. I tried installing optifine and it actually decreased my fps overall so I'm not sure whats going on. I tried downgrading to 3.1 again and even 3.0 and still having lag issues. I'm playing on a SSD with a I7 7700k, dual sli 1070 ti, 32gb ram with 20 allocated to MC.
