(adsbygoogle = window.adsbygoogle || []).push({}); The other day MC was running smoothly and had high FPS. I was using Nodus and noticed xray wasn't showing any blocks so I added some. After that, when xray was enabled every block that was underground was a type of ore (I imagine this was because the server), and I began to have 1-3 FPS. I deleted the xray.nodus file, deleted Nodus completely and tried running it with a regular client but nothing has changed. Another thing is MC will run smoothly at the Main Menu when I first start it, but when I go into a server or a SP world, I even get low FPS on there.

Do you by any chance have a cracked copy of Minecraft?
I used to use the cracked launchers and experienced heavy lag.
Now I have a premium version and I hardly have any lag, even on a crappy computer.
Hope this helps

No, I have a premium launcher.

Try lowering your video settings it should work

I've also tried that. No matter how low I put the settings, I still get low FPS.

I sorta fixed the problem. I restored my PC to a later date, and it seemed to make chunks load faster. But everytime I move, it drops when it starts to load new ones. I also have command delay. When I'm in a server, whenever I type something in the chat, or doesn't send till 30 seconds later. And when I try to move, it'll be a second delay and sometimes it'll keep moving me like I'm holding the button down.

From the look of it. Its your Computer

Minecraft is CPU based and your system well has a weak CPU. The computer isn't really decent for gaming only decent for browsing the web and watching videos.

Who cares tbh it is a bunch of blocks that you hit all day I don't see frame rte effecting that experience

have you tried giving minecraft more usable memory also install the 64bit java thats what helped me
