Hey there everyone!

I am a little stuck, and was wondering if anyone can provide some help.

I have a Samsung Chronos Series 7 Notebook. And I'm running Fedora 23. When running Minecraft, it grinds to a halt, and if I hit 10FPS it's a miracle. I start the jar file allocating plenty of RAM, and even a vanilla Minecraft is unplayable.

You would automatically assume it's because my specs are simply not good enough, however, my specs are this:

RAM: 4Gig

CPU: 2.40GHz x4 (i5)

HDD: 1TB (20% used)

The graphics have Optimus technology. However, having used Bumblebee on Fedora 22, and noticing that running my NVidia card simply turns the laptop into fireplace, I opted not to use it, and thus am using the built in graphics Intel provides. I have taken a few steps in order to try and make it easier on the hardware. Turning down pretty much all graphical elements of the game, which gave a only a few seconds of Framerate boost, and then grinding to a halt again. Also, I thought, perhaps a lightweight DE might help. So I installed XFCE, and switched into it to play. No difference.

When I start the game, I notice (through top) that my CPU goes to hell...running at a whopping ~350%

Anyone have any ideas?

EDIT: I have 8G of Swap, but this wasn't touched

When you run top, how much of that CPU usage comes from Minecraft? Also, you may wish to install and use iotop instead, to monitor disk usage and see if that's an issue. You didn't say, but with 4 GB RAM, you should have some swap; is it being used?

Thanks, I edited my post (up for moderation), and have 8G of swap that wasnt being touched. Also, in regards to the CPU usage, an average of 200% CPU usage is being used by java...so minecraft

happened to me on ubuntu as well, imho just leave gaming for windows for now, except for non-demanding games like chess or battle for wesnoth etc
