            <title>[MCPE-19612] Performance</title>

                <project id="10200" key="MCPE">Minecraft (Bedrock codebase)</project>
                    <description>&lt;p&gt;The world size is 94.6mb and after exploring for a couple hours now it seems when it&apos;s chunk loading, or something, the fps drop and my CPU usage shoots to 95% for some reason.  I&apos;ve tried various things to remedy the problem, but it appears there&apos;s nothing that can be done on my end. &lt;/p&gt;

                            <comment id="390830" author="anzestral" created="Sun, 25 Jun 2017 17:15:42 +0200"  >&lt;p&gt;I have the same problem on my i7-4770k (with a gtx 780 ti) and Minecraft 1.1.2 running on an SSD. I typically play with a render distance of 32 chunks but the issue also appears with much lower distances.&lt;/p&gt;

&lt;p&gt;On fresh worlds everything runs smooth with cpu loads of just a few percent when idle or just moving around the map very little. Going to unexplored parts of the map the cpu load increases to around 20%, so generation of new chunks doesn&apos;t seem to be the issue. However, after playing for some time and exploring more of the map (starting at map sizes around 50Mb) I started to experience cpu load spikes to 100% causing strong lag and decrease of fps for several seconds even when not exploring new parts of the map.&lt;/p&gt;

&lt;p&gt;This only appears when I launch the map locally (on two different machines). Exporting the map to a realm results in no lag (although the load on the realm might also spike), so I assume it&apos;s no problem with the rendering but rather with loading existing chunks.&lt;/p&gt;</comment>

                            <comment id="371964" author="morgwenna" created="Tue, 14 Mar 2017 12:18:53 +0100"  >&lt;p&gt;Agree it still affects 1.0.4 but improved. Oceans and dense tree chunks are still slow when loading. Worse when you hold a map see MCPE 18427.&lt;/p&gt;</comment>
                            <comment id="371696" author="darkelord" created="Sun, 12 Mar 2017 15:55:44 +0100"  >&lt;p&gt;Affects 1.0.4&lt;/p&gt;</comment>
                            <comment id="370004" author="nilmagus" created="Tue, 28 Feb 2017 03:11:17 +0100"  >&lt;p&gt;When I&apos;ve explored a fair amount of the map, similar to OP&apos;s world size (101.3Mb here), I experience similar performance issues.&lt;/p&gt;

&lt;p&gt;Specs:&lt;br/&gt;
Core i7 7700K&lt;br/&gt;
16Gb DDR4-3000&lt;br/&gt;
ASUS GTX 1070&lt;/p&gt;

&lt;p&gt;There is no reason this PC should be pegged at 100% CPU while travelling, when the Java version works fine. There&apos;s a several second delay when porting from the overworld to the nether or back, and nothing but particles load during this time. I dropped my chunk viewing distance to 40 and particle distance to 60, with very little noticeable difference.&lt;/p&gt;</comment>
                            <comment id="359494" author="samgamgee55" created="Sat, 11 Feb 2017 21:47:04 +0100"  >&lt;p&gt;This isn&apos;t a bug, it&apos;s the computer trying to preform all the tasks Minecraft PE is throwing at it. So I&apos;d say this isn&apos;t a MCPE problem. &lt;/p&gt;</comment>
                            <comment id="358914" author="darkelord" created="Fri, 10 Feb 2017 08:28:31 +0100"  >&lt;p&gt;This bug is still not fixed in 1.0.3.&lt;/p&gt;</comment>
                            <comment id="354597" author="flesh420" created="Mon, 16 Jan 2017 22:11:04 +0100"  >&lt;p&gt;Yes.  That&apos;s happened to two worlds of mine.  And it&apos;s repeatable every time. The more chunks it seems, the more lag.&lt;/p&gt;</comment>
                            <comment id="354506" author="zoerbshun" created="Mon, 16 Jan 2017 14:24:35 +0100"  >&lt;p&gt;I have this issue also and it is also repeatable.&lt;br/&gt;
Steps to reproduce:&lt;br/&gt;
1. create new world, any seed, creative or survival.&lt;br/&gt;
2. travel in the world in a straight line, any direction about 4096 chunks. (approx. 2, 1:16 scale maps)&lt;br/&gt;
3. watch your CPU usage pin to 100% as you travel.&lt;/p&gt;

&lt;p&gt;So as you add more chunks to your game data. the more lag the game experiences.&lt;/p&gt;</comment>
                            <comment id="352435" author="flesh420" created="Wed, 4 Jan 2017 17:49:03 +0100"  >&lt;p&gt;When the world was first created there wasn&apos;t any lag, at least not like this.  But a buddy and I traveled for hours and now it&apos;s laggy. So that&apos;s why I think it might be a chunk loading issue, or something. I&apos;ll probably create another world with infinite unticked and test.&lt;/p&gt;</comment>
                            <comment id="352375" author="phoenixpinion99" created="Wed, 4 Jan 2017 11:36:15 +0100"  >&lt;p&gt;I&apos;m not sure though, but it&apos;s sure laggy when flying in creative mode, even if the world&apos;s size is small, right? So let&apos;s just say this issue have something to with loading chunks... I&apos;m not so sure myself.&lt;/p&gt;</comment>
                            <comment id="352351" author="flesh420" created="Wed, 4 Jan 2017 08:10:18 +0100"  >&lt;p&gt;Now the world size is 101.3mb?&lt;/p&gt;</comment>
                            <comment id="352333" author="phoenixpinion99" created="Wed, 4 Jan 2017 05:11:28 +0100"  >&lt;p&gt;I think maybe your world just have capped the limit, 94.6mb, max size of a world.&lt;/p&gt;</comment>
