pc optimizaion

i'm tired of seeing minecraft java edition lagging on high end pc's just because is optimazied as crap, java edition is only on pc and fps are super instable i can have 180 fps and drop to 10 and even if it is for a split second it triggers me and i don't know why a game made of only cubes can lag on a 3080ti, i know it's hard to add nvidia dlss but good optimization is a good solution, so please do someting to stabilaze fps and don't make the game lag on high end pc's
