Trying to find an old YouTuber?

I used to watch him awhile back. His main game was Minecraft. Heres some stuff I remember about him:
-I remember that he hated using gravel anywhere and just hated it in general.
-In one of his playthroughs, he built a house into the side of a mountain, complete with windows
-In said house was a fireplace that would change back and forth between fire and stairs down with the press of a button
-He also made a graveyard with a secret door leading to a crypt he built and also in the same hill, had one of those doors that opened if you hoe'd the land.

I think his username started with a T but I'm not too positive on that. Is this ringing a bell at all? I feel like I know it but his name just doesn't come to me. Please and thanks

Why is Minecraft such a popular game?

In terms of graphics, the game is sub-par. The concept of the game itself is far too simplistic too have acquired such a large fan-base, and there are no special features of the game that make it carry any more significance than other low-quality games, and yet it thrives economically and socially. What exactly is so great about Minecraft?

Why is Minecraft running incredibly slow?

Before you ask, I'm aware of my laptops specs and they are very capable of running minecraft. In fact I've been playing it all week with 60fps minimum. (Might be low, but still absolutely playable).

I'm confused because about an hour ago, it suddenly dropped to like. 1fps. I can't even check the actual frame rate because it is running that slowly, but I can assume it is in that region or less. Completely unplayable. I've restarted MC and my laptop multiple times & tried different versions of MC. Still 1fps. Wtf has happened? Lol.
