when regularly playing I get about 300-400 fps, but for a very very quick second it drops to 4, then back up, then maybe 10-15 seconds later drops again. I've diagnosed that the problem has something to do with memory garbage recycling due to optifines lagometer thing and that my memory utilization (5gb/16gb allocated) rises to about 40% then dumps back to around 15%. The problem occurs on 1.15.2 and 1.16.1, have not tested other versions. I have changed jvm arguments adding -Xmn128M, but that just causes more drops, but that just causes it to drop more frequently still bringing me down to 4fps. I want to ask if anyone else has this problem or know a solution?
