            <title>[MC-168] Lag on some superflat maps</title>
                <link>https://bugs.mojang.com/browse/MC-168</link>
                <project id="10400" key="MC">Minecraft: Java Edition</project>
                    <description>&lt;p&gt;1.3.2 runs smooth, but starting from at least 2 snapshots before the 1.4 pre-release I&apos;ve had a hard time playing some superflat maps.&lt;/p&gt;

&lt;p&gt;Normal maps play fine, no more lag than usual and no eventual crawl. Some of the presets for superflat also have no issue.&lt;/p&gt;

&lt;p&gt;Try the &apos;Overworld&apos; preset though, and you may experience lag. The lag leads to eventual crawl which leads to items not being placed in chests or your inventory properly.&lt;/p&gt;

&lt;p&gt;I will try different combinations of features when I have more time and report which features are causing the lag.&lt;/p&gt;

&lt;p&gt;Let me be clear again - 1.3 ran fine on superflat, the normal superflat runs fine on my 1.4.x, but it is certain features of other presets and custom maps that is causing the lag. My computer runs MC fine 99% of the time.&lt;/p&gt;</description>

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>
                            <comment id="17574" author="drmule" created="Sat, 3 Nov 2012 11:29:12 +0100"  >&lt;p&gt;I&apos;ve re-worded my explanation. I had no idea there were any lag issues before 1.4.x came along because I didn&apos;t have any myself and I dare say I&apos;ve had an fps increase too, just not on the problem superflat configurations.&lt;/p&gt;</comment>

                            <comment id="13649" author="ray73864" created="Thu, 25 Oct 2012 23:59:05 +0200"  >&lt;p&gt;would look at your computer first.&lt;/p&gt;

&lt;p&gt;Mine has no issues with superflats, in fact, i got better FPS using 1.4.1pre than 1.3.2, almost 700FPS in 1.4.1pre on a superflat world.&lt;/p&gt;</comment>
