Experiencing excessive Lag and Stuttering which occurs randomly while playing Minecraft Java v1.21
Sometimes it happens right away, sometimes it happens after a hour or longer of game play.
It maxes out my GPU at 100% then grinds the FPS down to 1 and starts to fluctuate between 1 - 20 FPS with the GPU use fluctuating between 60% - 100% and continues with this until it grinds the game into a Lock Up, and I'm forced to shut it down via Windows Task Manager.
The problem never occurred while playing v1.19 or v1.20 ... where I would have GPU use no higher then 30% and FPS in the 120+ range.
This issue occurs for me in both single player, and in multiplayer with my wife connected to my world.

I'm sorry but no, this is NOT a duplicate of a ""Single Player" issue.
This also occurs while in Multiplayer.
My wife and I recently lost an entire world we had just started because this issue caused my PC to lock up and I was forced to crash it out via Task Manager, which resulted in the world not being correctly saved.
For the record, the above screenshots are from another multiplayer world that my Wife and I just created together.
@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 did some further experimentation on this and I've found that when this stuttering/lag starts to occur, there is typically a Trial Chamber in the vicinity somewhere under the surface.
Moving closer towards it, tends to cause the Stuttering/Lag to get worse... but it does not stop when moving further away, it just continues to build up until it just locks up my game.
Thank you for your report!
