            <title>[MCPE-18171] Dragon Attack Particle and Lingering Potion Lag.</title>
                <link>https://bugs.mojang.com/browse/MCPE-18171</link>
                <project id="10200" key="MCPE">Minecraft (Bedrock codebase)</project>
                    <description>&lt;p&gt;Xperia Z5&lt;/p&gt;

&lt;p&gt;When the ender dragon shoot it&apos;s dragon breath. It&apos;s effect remains forever and still gives a circle of purple particles on the ground causing massive lag &lt;/p&gt;

&lt;p&gt;AMAN4700 Edit: This also has to do with the lingering potion effects, because they are very identical.&lt;/p&gt;</description>

The particles are a lot to handle for phones and the game crashes every time a lingering potion is thrown or the Ender Dragon shoots the dragon&#8217;s breath.&lt;/p&gt;</comment>

&lt;p&gt;I also think there needs to be an option to disable or minimal the particles for the phone users. i think that option is most needed on the phone versions of Minecraft!&lt;/p&gt;</comment>

They need to clean that up. The aoe is too large to even run from, and the lag when two or three are on the ground is horrendous.&lt;/p&gt;</comment>

If the stars created by the end portal are considered particles, that might also explain the lag when you look towards the horizon of an end gateway portal.&lt;/p&gt;

&lt;p&gt;The amount of particles were supposed to be regulated by the particle render distance, but it seems to only limit particles far away, which is not helpful.&lt;/p&gt;</comment>
                            <comment id="369242" author="mega_spud" created="Thu, 23 Feb 2017 17:47:00 +0100"  >&lt;p&gt;Tested in 1.0.4.0, here are the approximate FPS readings from the beta header:&lt;/p&gt;
&lt;ul class=&quot;alternate&quot; type=&quot;square&quot;&gt;
	&lt;li&gt;&lt;em&gt;Starting FPS in The End, no potion/attacks: ~52fps&lt;/em&gt;&lt;/li&gt;
	&lt;li&gt;Ender Dragon charge attack: ~ 33fps&lt;/li&gt;
	&lt;li&gt;Ender Dragon Breath attack: ~26fps&lt;/li&gt;
	&lt;li&gt;If I fire 10 lingering health potions on the ground: ~30fps&lt;/li&gt;
	&lt;li&gt;Spamming lots of lingering potions at once: ~6fps&lt;/li&gt;
&lt;/ul&gt;


&lt;p&gt;&lt;em&gt;Again, tested on my Samsung TabPro SM-T520 on Android 4.4.2&lt;/em&gt;&lt;/p&gt;

&lt;p&gt;The EnderDragons Ender Charge attacks that leave many particles on the ground can reduce the FPS significantly, as can the use of lots of lingering potions.&lt;/p&gt;

&lt;p&gt;The Dragons&apos; breath attack does not seem to reduce the FPS quite as much, but that might be because fewer breath attacks occur at once.&lt;/p&gt;

&lt;p&gt;Attached screenshots:&lt;/p&gt;

                            <comment id="347780" author="woodensword" created="Thu, 8 Dec 2016 04:24:07 +0100"  >&lt;p&gt;This also happens in PC Minecraft (version 1.11) and the framerate stays at 1 FPS forever because the time between shots is shorter than the time that the lingering stuff lasts. It makes The End unplayable.&lt;/p&gt;</comment>
                            <comment id="347573" author="soleh pinner" created="Tue, 6 Dec 2016 15:27:35 +0100"  >&lt;p&gt;Lingering potion cause FPS dropping because particle effect.&lt;/p&gt;</comment>

It causes a frames drop but not that much as it used to be in the first build. But the Ender Charge (the purple ball thing) effect lasts for almost forever. And the issue was talking about the Ender Charges not the dragon breath but it&apos;s been edited by an MCPE MOD.&lt;/p&gt;</comment>
