MC-145256 Minecraft causing MacBook Pro to heat up, using up to 350% CPU Duplicate

Comments

Surely they'll get around to it eventually, right? I mean, it'd be a shame to force paying customers to be unable to play past 1.12.2 just by leaving a reported problem unfixed. Certainly they can't have forgotten about us.

Backhanded remarks aside, I'm kinda starting to lose hope, too.

1.15.2 also has the bug.

So, what are we supposed to do now since it's been marked as fixed when it isn't? How do we get this reopened and properly seen to?

It's the middle of December, 1.15 is out, and guess what's still not fixed? Minecraft eats my CPU, meaning that I can't play it. Mojang, seriously, reopen this.

Even with the render distance at 2 chunks it still consistently stays around 80-110% CPU usage, and that's after the 250% when entering the world. That's with all the other settings down like OP has in the comment above. My computer specs are in the bug report I made that was closed as a duplicate of this one, which was made after mine. Still don't entirely get that, but as long as the issue is being taken care of I'm not troubled.

As OP has stated, the problem is the computer heats up; If I put my hand near it, I can feel the hot air being blown out by the fan, which is also very audibly working pretty hard. The cause of this behavior is the abnormal CPU usage. Now, this is not something that was an issue in 1.12, so I'm inclined to believe that this is a bug, introduced somewhere around 1.13.2 from what I've recorded of trying to figure it out.

I find it completely unacceptable that we are being told to do things to mitigate the problem that we've already tried and found to not work. Turning down the render distance does not work. Turning down the resolution does not work. Bringing the graphics settings down does not work. The only thing that works is reverting to a version that does not have the bug.

Still don't know why this hasn't been reopened when it hasn't been fixed. My report even got closed as a duplicate.

Yeah, game still gets up to 200% in the larger window, 100% in the smaller one.

That does sound quite awful, David, however I'm afraid you have no business commenting in this specific issue unless you're having the same problem. Instead, you ought to create your own issue if your problem seems to be caused by Minecraft.

Just went and took three screenshots, one in fullscreen mode and two in windowed, and I have to say you're right about the resolution. I'll have to upload those as well.

Yeah, pretty sure that's just a fluke. Hasn't gone up past 350% any other time I've had it open, usually tends to be around 300% plus or minus 30% when opening up the game or loading a world.

Not OP, but I've also been having the same issue for a while on my MacBook Pro, still happens in 1.13.2 for me.
