            <title>[MC-8304] Lag Spikes / FPS Drops</title>
                <link>https://bugs.mojang.com/browse/MC-8304</link>
                <project id="10400" key="MC">Minecraft: Java Edition</project>
                    <description>&lt;p&gt;Ever since I updated to the Snapshot 13w04a(also 13w03a), I&apos;ve had massive FPS Drops in the Overworld, which has made me pretty much unable to play. This doesn&apos;t affect any other dimension, as I have about 96-160 FPS over all in the end, and 110-180 in the nether. Back in the later snapshot (13w02b) I never had this problem. But now I can&apos;t get more than 16FPS in the overworld. &lt;/p&gt;</description>

I know my friends computer does this but his old one didn&apos;t. It is an hardware or java issue. So this is an duplicate.&lt;/p&gt;</comment>
                            <comment id="39767" author="sauilitired" created="Fri, 25 Jan 2013 16:24:03 +0100"  >&lt;p&gt;This is not a duplicate, since the other ticket is about FPS going down for a couple of seconds, then going up again. Mine stays down for the whole time, thank you.&lt;/p&gt;</comment>

I added a screenshot of a weird CPU-thingy, and I got reasons to think that the unspecified (Seems to have something to do with the particles, even though I have them on decreased) is causing it. Any thoughts? &lt;/p&gt;</comment>
