 Description   

I have a Windows 10 laptop with Minecraft Windows 10 Edition v1.0.4. When I play some worlds or in a Realm, Minecraft responds pretty well. But I have a Survival world that is 104.6 MB. (I am trying to get all the achievements, and I had to explore a bit to get cactus and cocoa beans.)

When I open that world, there is a lot of lag. The CPU in task manager goes near 100%. I am trying to kill the Enderdragon now and it's not that easy. I've turned down most of the video settings (except I need a little render distance so I can see which towers I have to take out).

I've found that the laggiest - highest CPU times are when I join the world, and when I go through the Nether portal (either way) or when I go through the End portal. So, it gets high CPU when it has to render the world from scratch.

What else do you need?

You'll need to provide more information. I have a world that is 380 MB, and Minecraft barely uses any CPU (and no I don't have an expensive new CPU: Intel core i7 processor from 7 years ago).
