            <title>[MC-2434] Huge lag spike renders game unplayable</title>
                <link>https://bugs.mojang.com/browse/MC-2434</link>
                <project id="10400" key="MC">Minecraft: Java Edition</project>
                    <description>&lt;p&gt;After exploring a very large section of the map and creating around 77,000 chunks, if I move back to pre-rendered chunks a short distance away the framerate drops down to 0 FPS and will move one frame only every few seconds. Closing the window and reopenning fixes this problem, but it will persist continuously after moving a distance. This is very frustrating when you have distant mines and minecart systems.&lt;/p&gt;</description>

&lt;p&gt;In some LP videos, they would experience temporary severe lag issues while they are just building/mining stuffs. Usually, when it lags, they are near spawners. I may not be correct, but it&apos;s a good direction to look into seeing if spawning mobs and loading chunks at the same time may be causing the issue.&lt;/p&gt;</comment>

I totally agree that this is frustrating cause I have this problem too, especially in a developed area.&lt;/p&gt;</comment>
