[MCPE-28439] Framerate drops in *some* chunks.

I'm seeing weird, significant framerate drops in certain chunks for no observable reason. The framerate drop ceases instantly when moving out of afflicted chunks. The direction you are facing has absolutely 100% no influence on the framerate drop and as such it's also not something terrain occlusion seems to prevent from happening. In a way it almost looks more like something like entity lag because of that.

Example coordinates: (1164,-96) in seed -1430031728

Addition: the framerate drop seems more significant in my 'older' survival world than the newly created creative copy of the world (I can still notice it though). I'll see about attaching my survival world also.

I saw this 3 times today in my 1.2.3 world, also on win10. all 3 times were in deserts, only once was in newly generated chucks.

This is on the edge of a desert, probably including a portion of it, Ed.

This is probably a duplicate of MCPE-28028. Deserts frequently have shallow caves full of zombies and husks. If these are near enough to the surface and close enough for them to sense you, they try to pathfind to you, but sometimes the cave has no opening so their pathfinding is unsuccessful. That should be the end of it, but due to a bug it causes severe lag in the current release. It can also happen in other biomes where caves are near to the surface, in villages with zombies trying to get to the villagers but being stopped by doors, and near animals trying to get to food you're holding if they're stopped by a fence, wall, etc. We think all these issues are stemming from the same root cause.

Thanks Auldrick. I'll update this if a future patch to 28028 fixes this.

Update: I dug around in creative, but I am unable to find said cave.

Hmm, that's concerning, because we have almost no cases of this kind of scattered local lag that haven't been explainable as the MCPE-28022/28028 issues. Perhaps we'd better consider this not a duplicate after all. Having your world download should be a big help to the devs.

I already added that as an attachment. Coordinates of the laggy chunks are in the post.
