Minecraft lagging on good computer (Java)

[PackYourBaggins]

I started getting back into Minecraft again and since I returned to it, I've been dealing with some lag here and there, but I assumed that was just how Minecraft ran. Mostly I'm getting small stutters when I mine blocks. Every single time I break a block, the game stutters a little without fail, but I was still getting very high FPS. But yesterday I accidentally set fire to a big tree someone built (lol), and I then discovered that when something like that is happening, oh boy, my game absolutely tanked. It plummeted to less than 10 FPS whenever I got near the burning tree. And when me and my friends dumped a bunch of water on the tree to put it out, the water was also tanking my game just as much as the fire did. I don't understand why this was happening, especially since I have a really good system. It wasn't happening to my friends' game. Just me. What can I try to fix this?

 

My specs:

 

i7 4770K @ 4.2Ghz

EVGA 1080Ti

32GB Kingston HyperX Beast 2400Mhz RAM

Corsair 180GB SSD

G-Sync 1440p monitor (144Hz)

Is this program plug-and-play, or will it take some configuration?

I've downloaded and installed it, but it didn't seem to improve anything sadly. Still getting the same stutters when mining blocks.

Are you playing on a server exclusively or has this happened in single player as well? I at least know from experience that the lag you described seem to happen to be when connected to a server or when a lot was going on in the world else where.

It is also possible that Minecraft is not taking advantage of the ram it needs. I seem to remember always forcing it to have access to more RAM at startup. Never played it on a "good" rig though.

I'm playing on a friends realm. Not sure if that's different to a server. I'm a bit of a MC noob. I did just now try single player, and not only was I still getting lag when mining blocks and chopping trees, it was even laggy when just walking around. At least walking around in my friends realm is butter smooth.

 

Also, how do I force it to have more RAM access?

I can't remember off the top of my head how to. But I do know there are plenty of YouTube videos on the subject. Also a realm to my knowledge would work about the same as a server. Their just hosted by those who own Minecraft. There is also this wikihow page that seems to have the information you seek. https://www.wikihow.com/Allocate-More-RAM-to-Minecraft If that doesn't work it is also possible Java isn't getting enough ram. Though that's a bit of a deeper whole than I'd be willing to dig before you try this first.
