            <title>[MC-11878] After updating to the 1.5 version, the game uses a huge amount of memory and has terrible lag</title>
                <link>https://bugs.mojang.com/browse/MC-11878</link>
                <project id="10400" key="MC">Minecraft: Java Edition</project>
                    <description>&lt;p&gt;The game is consuming astronomical amount of memory, causing terrible lag. Few minutes before playing the new version I updated Java from 16 to 17, so I don&apos;t know if this problem is really caused by the game or by the new Java version.&lt;/p&gt;

&lt;p&gt;I created a new issue because I don&apos;t know the cause, so I&apos;m not able to simply vote or comment on another issue.&lt;/p&gt;</description>
                <environment>Java Version 7 Update 17&lt;br/&gt;
Microsoft Windows XP Service Pack 3 (because Minecraft doesn&amp;#39;t appears to work well on Ubuntu)&lt;br/&gt;
NVIDIA GeForce 8400 GS</environment>

&lt;p&gt;1.5.1 works incredibly well. The performance is amazing. I didn&apos;t noted too much lags. The memory usage is the same (200MB -&amp;gt; 500MB -&amp;gt; 700MB -&amp;gt; 1GB -&amp;gt; 1.2GB, etc.)&lt;/p&gt;

&lt;p&gt;I added too 4 crash reports: 2 from 1.5 and 2 from 1.5.1. Each version have a crash report with the render distance configured to &quot;normal&quot; and one configured to &quot;large&quot; (I have a 32-bit system, but it&apos;s horrible to travel on Nether with less than &quot;large&quot;, so I use this configuration).&lt;/p&gt;</comment>

If so, please update the affected versions in order to best aid Mojang ensuring bugs are still valid in the latest releases/pre-releases.&lt;/p&gt;</comment>

When you let go, a crash will be generated.&lt;/p&gt;</comment>
