Here is an update of the current status for me on my PC.

I have a video recording of what was happening while i was in game, but it is to large to upload here so what would be the best way to show it and would it be helpful?

On 64 chunk render distance when loading into the world
Jumped from ~13% on loading screen to ~80%+ immediately after loading into a world, then got up to 100% for around 10 seconds. (1:38-1:48 in recording)
Stayed at 70%+ range for around 30 sec in game where it then would stay in-between 40%~75%
dropped down to 10%~20% in the neather
spiked up to 90% again when leaving the neather
stayed above 70% for around 30 sec again, then stayed in-between 40%~70%

set render distance to 48 chunks
went back into the neather, stayed around 10%~20% again
back to the overworld jumped back up to 90%+ for about 10 sec this time then dropped down to 70%~80% when flying around
hovered around 20%~50% when moving in smaller chunks

set render distance to 32
dropped to ~15%-40%
when moving it was higher
neather again, still low
back to overworld, back up to 90% for around 3 sec, then hovered between 15%-40% when moving.

No resource pack(s) or behavior pack(s) were turned on/active.

I have been having the exact same problem, I though it had to do with the resource pack am was using, but it was working fine in pervious versions, and even without it on I am still having upwards of 70% CPU usage with 80 chunk render distance.

even the simple thing of moving caused a lag spike for me.
