I don't know why this is happening but it was perfectly fine before but after the update it just got very bad idk why, I asked reddit and no one seemed to know what the problem was. One person told me to talk to amd about this. I talked to epic and they tried everything but couldn't help me. I think in the new update they added something that amd gpus in particular don't support. I think in the new drivers hopefully if they add something that is compatible with the game, then it might work. There's a new update but I'm afraid to upgrade to that one coz the one I have right now seems very stable.
