            <title>[MCPE-14383] Framerate drop when many entities are &quot;there&quot; but not visible</title>
                <link>https://bugs.mojang.com/browse/MCPE-14383</link>
                <project id="10200" key="MCPE">Minecraft (Bedrock codebase)</project>
                    <description>&lt;p&gt;Did not affect 0.14.1/0.14.0.&lt;br/&gt;
The framerate drops seemingly random while being in caves or looking at huge, sponge-like structures.&lt;br/&gt;
I was able to track down the cause to too many/any entities just &quot;being there&quot; somewhere in the world within the player&apos;s view angle. The entities do not need to be visible, it is sufficient for them to be in the &lt;b&gt;possible&lt;/b&gt; view angle.&lt;br/&gt;
I suspect some kind of rendering optimization algorithm not taking entities into account.&lt;br/&gt;
Why entities? I commented out the code in &quot;/data/shaders/entity.vertex&quot;. After restarting the game, the random lags were completely gone.&lt;/p&gt;


&lt;p&gt;What I expected to happen:&lt;br/&gt;
No framerate drop with entities existing behind blocks but not being visible to player.&lt;/p&gt;

&lt;p&gt;What actually happened:&lt;br/&gt;
Heavy, unexpected framerate drop with entities behind blocks etc.&lt;/p&gt;

&lt;p&gt;Steps to reproduce:&lt;br/&gt;
1) Find a monster spawner in a cave.&lt;br/&gt;
2) Wait for enough monsters to spawn.&lt;br/&gt;
3) Walk around in the cave. You will notice a framerate drop.&lt;/p&gt;</description>

I don&apos;t believe there is a way to return to older versions of Minecraft, at least on iOS.&lt;/p&gt;</comment>
                            <comment id="308304" author="henry_anonym" created="Sun, 29 May 2016 15:05:13 +0200"  >&lt;p&gt;On the other hand, Minecraft PE is now unplayable on my iPhone 4, as neither the touch controls nor the camera do react to my finger tips anymore - due to this bug. &lt;br/&gt;
Also, when speaking of heavy framerate drops I mean an estimated 0.5 FPS with ~40 entities not being visible to the camera.&lt;/p&gt;

&lt;p&gt;As long as this bug is not resolved, MCPE should be marked as &lt;b&gt;unplayable&lt;/b&gt; or &lt;b&gt;incompatible&lt;/b&gt; for iPhone 4 and lower to not displease users who might buy or update MCPE on a version greater than 0.14.1.&lt;br/&gt;
Another solution might be to give users the ability to stay on a specific version of MCPE and/or give them the ability to downgrade their MCPE.&lt;/p&gt;

&lt;p&gt;Decisions are not up to me, but I think these problems could have affected customer satisfaction in a serious way and they will keep affecting customer satisfaction unless there is at least some kind of solution. Some customers might feel really betrayed when realizing: Whoops, the app I have spent 6$ on does not work on my device.&lt;/p&gt;</comment>

                            <comment id="304809" author="luisrobles" created="Sun, 15 May 2016 16:15:18 +0200"  >&lt;p&gt;Why do you think this is a bug?, In my opinion, iPhone 4, has an old chip (A5), and MCPE requieres more resources (frequency and RAM). I think, the framerate drop it&apos;s normal for an old device.&lt;/p&gt;</comment>
