            <title>[MC-11875] 1.5 HD Textures: Very poor performance with 32x packs and up.</title>
                <link>https://bugs.mojang.com/browse/MC-11875</link>
                <project id="10400" key="MC">Minecraft: Java Edition</project>
                    <description>&lt;p&gt;NB: This is not a duplicate of &lt;a href=&quot;https://mojang.atlassian.net/browse/MC-11595&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;this issue&lt;/a&gt; as I am experiencing a significant performance drop with all HD packs, 32x and up.&lt;br/&gt;
&amp;#8212;&lt;/p&gt;

&lt;p&gt;I am the author of &lt;a href=&quot;http://www.minecraftforum.net/topic/657949-&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;Defscape&lt;/a&gt;, a 16x, 32x and 64x texture pack.&lt;/p&gt;

&lt;p&gt;Having used 1.5 for quite some time while texturing, I&apos;ve noticed that native HD texture performance is very poor.&lt;/p&gt;

&lt;p&gt;Changing settings doesn&apos;t seem to affect my FPS, although V-sync on tends to lower my frames.&lt;/p&gt;

&lt;p&gt;The following results use the settings:&lt;/p&gt;

&lt;p&gt;Distance: Normal&lt;br/&gt;
Graphics: Fancy&lt;br/&gt;
Smooth lighting: On/Maximum (there is no difference in performance between minimum/maximum)&lt;/p&gt;

&lt;p&gt;&lt;b&gt;13w12~&lt;/b&gt;&lt;/p&gt;

&lt;p&gt;Default: 40-50 FPS (70 FPS looking at the sky - 75 FPS looking at the ground)&lt;br/&gt;
16x: 35-50 FPS (60 FPS looking at the sky - 65 FPS looking at the ground)&lt;br/&gt;
32x: 25-45 FPS (45 FPS looking at the sky - 50 FPS looking at the ground)&lt;br/&gt;
64x: 10-20 FPS (20 FPS looking at the sky - 30 FPS looking at the ground)&lt;/p&gt;

&lt;p&gt;Note: Although slightly smoother, frames are generally stuttery and unsmooth, no matter the figure in f3.&lt;/p&gt;

&lt;p&gt;&lt;b&gt;1.5:&lt;/b&gt;&lt;/p&gt;

&lt;p&gt;Default: 25-40 FPS (120 FPS looking at the sky)&lt;br/&gt;
16x: 20-35 FPS (70 FPS looking at the sky)&lt;br/&gt;
32x: 15-30 FPS (50 FPS looking at the sky)&lt;br/&gt;
64x: 10-20 FPS (20 FPS looking at the sky)&lt;/p&gt;

&lt;p&gt;Note: All frames are generally stuttery and unsmooth, no matter the figure in f3.&lt;/p&gt;

&lt;p&gt;&lt;b&gt;1.4.7:&lt;/b&gt;&lt;/p&gt;

&lt;p&gt;Default: 35-60 FPS (200 FPS looking at the sky)&lt;br/&gt;
16x: 35-60 FPS (200 FPS looking at the sky)&lt;br/&gt;
32x: 35-60 FPS (180 FPS looking at the sky)&lt;br/&gt;
64x: 35-60 FPS (180 FPS looking at the sky)&lt;/p&gt;

&lt;p&gt;Note: All frames are smooth.&lt;/p&gt;

&lt;p&gt;&lt;b&gt;1.5 &amp;amp; Optifine:&lt;/b&gt;&lt;/p&gt;

&lt;p&gt;Default: 60-100 FPS (240 FPS looking at the sky - 120 FPS looking at the ground)&lt;br/&gt;
16x: 60-100 FPS (220 FPS looking at the sky - 120 FPS looking at the ground)&lt;br/&gt;
32x: 60-100 FPS (210 FPS looking at the sky - 115 FPS looking at the ground)&lt;br/&gt;
64x: 60-100 FPS (210 FPS looking at the sky - 115 FPS looking at the ground)&lt;/p&gt;

&lt;p&gt;At the moment, the only way 1.5 is playable for me is by using Optifine which seems to fix all the lag-enducing issues that have been introduced between 1.4.7 and 1.5.&lt;/p&gt;

&lt;p&gt;That said, having to use a third party modification obviously isn&apos;t ideal and shouldn&apos;t be a prerequisite for smooth choppy-less gameplay with HD texture packs.&lt;/p&gt;

&lt;p&gt;If you wish to test this yourself, here are the different Defscape resolutions:&lt;/p&gt;

&lt;p&gt;Mediafire:&lt;/p&gt;

What sort of system are you using that out of 1.5.1, 1.5.2 and 13w18c you get 1.5.1 running best? &lt;/p&gt;</comment>

                            <comment id="65421" author="grum" created="Wed, 8 May 2013 06:23:15 +0200"  >&lt;p&gt;This means nothing. Minecrafts is far more demanding than any other game polygon wise. Especially since the full world is modifiable. Comparing it to anything static like Sauerbraten is like comparing apples and creepers.&lt;/p&gt;

&lt;p&gt;Also your 70-80 fps is with what version?&lt;/p&gt;</comment>

If with 1.5.2 you still have issues please use the larest snapshot or optifine/hdpatcher/whateverflavor thing if you need.&lt;/p&gt;

&lt;p&gt;The latest snapshot shouldn&apos;t have these issues, if they do please let us know (or buy better hardware &lt;img class=&quot;emoticon&quot; src=&quot;https://bugs.mojang.com/images/icons/emoticons/wink.png&quot; height=&quot;16&quot; width=&quot;16&quot; align=&quot;absmiddle&quot; alt=&quot;&quot; border=&quot;0&quot;/&gt;).&lt;/p&gt;</comment>

However I can confirm that the problem has been fixed completely for all texture resolutions in the 13w18 snapshot though, which is good news.&lt;/p&gt;</comment>

&lt;p&gt;Also being able to load them is most definitely not &apos;supporting them&apos;.&lt;/p&gt;

&lt;p&gt;With 1.5.1 testing with BDcraft 64x I have around 90 to 100 FPS With 128x it drops to around 40-50 FPS.&lt;/p&gt;</comment>
                            <comment id="63143" author="grum" created="Wed, 24 Apr 2013 21:44:54 +0200"  >&lt;p&gt;My goal this week was fixing those issues. It&apos;s not completely (nicely/properly) fixed but we&apos;ll have a huge performance improvement planned for 1.5.2.&lt;/p&gt;

&lt;p&gt;We&apos;ll fix the texture handling properly for 1.6 though, so expect it to be in that soon.&lt;/p&gt;

&lt;p&gt;&amp;#8211; Edit&lt;/p&gt;

&lt;p&gt;We just did something completely unacceptable performance wise but ... well ... we do not really care that much for highres texturepacks which is why we never noticed until it was out &lt;img class=&quot;emoticon&quot; src=&quot;https://bugs.mojang.com/images/icons/emoticons/biggrin.png&quot; height=&quot;16&quot; width=&quot;16&quot; align=&quot;absmiddle&quot; alt=&quot;&quot; border=&quot;0&quot;/&gt;&lt;/p&gt;</comment>

&lt;p&gt;Now in 1.5.1, I updated the texture pack to have the one compatible with 1.5, and I hardly get more than 15 FPS which is truly unplayable.&lt;/p&gt;

&lt;p&gt;I tried different versions of the pack (16x, 32X &amp;amp; 128x), the higher the slower, whereas in 1.4.7 there was no such differences in FPS.&lt;/p&gt;</comment>
                            <comment id="55721" author="dsohler" created="Wed, 20 Mar 2013 04:25:52 +0100"  >&lt;p&gt;1.5: 20 FPS looking at the sky&lt;br/&gt;
1.4.7: 180 FPS looking at the sky&lt;/p&gt;

&lt;p&gt;I don&#8217;t think that has anything to do with performance or hardware issues, Aaron. They just messed 1.5 up (and kind of &#8220;fixed&#8221; it in 1.5.1-pre).&lt;/p&gt;

&lt;p&gt;@d3fin3d have you tried the 1.5.1-pre snapshot?&lt;/p&gt;</comment>
                            <comment id="55650" author="aaronfranke" created="Wed, 20 Mar 2013 00:47:39 +0100"  >&lt;p&gt;HD packs obviously would lag more than default packs, as there are less pixels to render when you go down resolutions. Only use HD packs if you know your computer can handle them, your performance on the default texturepack tells me you do not have the best setup out there.&lt;/p&gt;</comment>
                            <comment id="53566" author="dsohler" created="Fri, 15 Mar 2013 17:11:31 +0100"  >&lt;p&gt;I can confirm that. I have a frame drop of around 70 percent with identical settings on same hardware.&lt;/p&gt;</comment>
