Minecraft lagging on good pc....completely stumped

[decentaoura0]

My computer runs any other game perfectly fine on high settings. I've uninstalled all old versions of Java and updated to the most recent version. I've allocated more RAM to the game to no avail. I have Optifine downloaded and installed. I'm at my wits end...Can someone please tell me why this game runs at 2-15 fps when it starts a new world and then after all chunks load and i move it drops to 0 fps should be well into the hundreds with these specs.
I have a
AMD Ryzen 7 2700x Eight-Core Proscessor
16gbs of dd4 at 3200mhs ram
Geforce GTX 1080
i am completely lost.
thanks

I would suggest you uninstall minecraft (and delete the %appdata%/.minecraft folder), update your nvidia driver if not already done and then reinstall minecraft without any mods like optifine. if then works fine you can narrow it down to things like optifine etc.

check the cpu/gpu temp and usage during the game?
What is the make and model of the PSU?
Fresh OS install?
Is that 1 stick of ram?

my cpu sits at 65c-70c and its spikes to 3.26ghz and my gpu sits at 52c, its 2 sticks of ddr4 gskill ram, my PSu is a evga supernova 750watt gold power supply and my os is 2018 windows 10 pro

65-70c on cpu? what else is using the cpu resourse? check for virus/malware?
