After you talked about a trial chamber, I went to go look and see, and I do not have a trial chamber under my build. This made me sad cuz I was hoping there was one.
@Nazrex,
I didn't put Multiplayer in my title because I almost always play on single player, but what you are describing is the same problem as mine, which is the one that Greymagic27 linked to. Just trying to help.
I worked with Community Support, I upped my RAM usage to 4GB from 2GM, then uninstalled my display drivers and reinstalled them with the WHQL version. I am still experiencing the problem of the game stuttering. The link to the last YouTube video I uploaded of my gameplay is linked here:
The problem persists after all of these suggested fixes and I hope that there is a fix to this problem by Mojang.
This does not have anything to do with chunk boarders, I can load into a game and not move from spawn and it still does it, and as the game runs, it gets progressively longer.

I had to upload it to YouTube as it was too large for this area. If it needs to be longer I can recreate it from game opening and go longer.
This is being reported by multiple users, I reported it as being rc1 and in 1.21 as well.
This is still happening after the switch to 1.21 on 6/13/2021
I created a duplicate of the Instillation and changed the arguments for the GC in the duplicate to test them out.

Here is the link to the youtube video of my game as I was playing.
