            <title>[MC-733] Extreme Framerate Drop</title>
                <link>https://bugs.mojang.com/browse/MC-733</link>
                <project id="10400" key="MC">Minecraft: Java Edition</project>
                    <description>&lt;p&gt;Basically, whenever I start up any game of MineCraft, FPS starts at around 150, or whatever crazy high number it should be, then it does this perfect parabolic slope DOWN to around 13-22 FPS which is NOT normal for my setup. &lt;br/&gt;
I have tried tweaking every setting, change java versions, deleting and reinstalling, older versions etc. &lt;br/&gt;
Might be an OS related issue though since I did just install Windows 8 today, but I feel like if I can run Battlefield 3 normally on here, i should be able to run MineCraft just fine.&lt;br/&gt;
The first time I noticed this bug, I had been playing the game for about 15 minutes and the games framerate had degraded to something unplayable like 5-8FPS and when I checked task manager it was taking 1.5gb of RAM, so at first I suspected a memory leak, but it doesnt seem like I can replicate that RAM usage. (I havent been able to play longer than 5 minutes however with this terrible bug)&lt;/p&gt;</description>
                <environment>Newest Java &lt;br/&gt;

Around 5-20 frames per second. Then it will rise to around 10-30 fps. By setting the java program&apos;s priority to high through Task Manager, it can rise to 15-40. I am running Windows 7.&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>

                            <comment id="14411" author="s3lg" created="Sat, 27 Oct 2012 17:06:19 +0200"  >&lt;p&gt;i thought that might have been what it was, the reason win 8 drivers dont work properly is because there probly only beta drivers im sure it will be fixed soon. but im glad you got it fixed &lt;img class=&quot;emoticon&quot; src=&quot;https://bugs.mojang.com/images/icons/emoticons/smile.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;Solution: Install Windows 7 Drivers&lt;br/&gt;
Lesson: Current Win8 Drivers suck?&lt;/p&gt;</comment>
                            <comment id="14289" author="rytherix" created="Sat, 27 Oct 2012 09:56:11 +0200"  >&lt;p&gt;quick note: I have tried the game on my Linux Mint partition, which is NOT on a SSD and has WORSE video drivers than my Windows installation, and the game runs fine on that. So its not a problem with my hardware&lt;/p&gt;</comment>
                            <comment id="13988" author="s3lg" created="Fri, 26 Oct 2012 16:12:11 +0200"  >&lt;p&gt;hmm, well as i have an ATI i cant try and see if it happends to me, but it could possibly be the nvdia win 8 drivers im not sure tho, i would go back to win 7 and see if it does it but thats up to you if you want to do that or not&lt;/p&gt;</comment>
                            <comment id="13983" author="rytherix" created="Fri, 26 Oct 2012 16:07:03 +0200"  >&lt;p&gt;Windows 8 Pro build 9200 64bit&lt;/p&gt;</comment>
                            <comment id="13979" author="s3lg" created="Fri, 26 Oct 2012 16:02:04 +0200"  >&lt;p&gt;ok, forgot to ask what version of windows are you using 32bit or 64bit?&lt;/p&gt;</comment>
                            <comment id="13977" author="rytherix" created="Fri, 26 Oct 2012 15:55:32 +0200"  >&lt;p&gt;Just tested and it DOES happen in superflat worlds as well. &lt;br/&gt;
It when I reload worlds the problem remains, there might be a correlation between chunks loaded and drop.&lt;/p&gt;

&lt;p&gt;I would like to mention, that anything that you would think to speed up performance DOES speed up performance but does so at an insignificant amount.&lt;br/&gt;
For Example: &lt;br/&gt;
Render Distance Far: 24 FPS&lt;br/&gt;
Render Distance Tiny: 35 FPS &lt;/p&gt;

&lt;p&gt;Looking through heavy jungle (what is seen in original screenshot)&lt;br/&gt;
All settings maxed: 8FPS&lt;br/&gt;
All settings lowest: 20FPS&lt;/p&gt;

&lt;p&gt;Keep in mind All settings maxed I use to be able to run this game at 60+FPS&lt;/p&gt;


&lt;p&gt;EDIT: I am using the newest Nvidia Drivers - 306.97 and Intel HD drivers - 9.17.10.2287&lt;/p&gt;</comment>
                            <comment id="13973" author="s3lg" created="Fri, 26 Oct 2012 15:49:34 +0200"  >&lt;p&gt;as weird as it may seem Minecraft is more hardware demanding then BF3, ive played minecraft on win 8 and i got the ussaul fps of 300fps now ofc my PC is way overpowerd for minecraft as i have a intel core i7 3820 @ 4.6ghz 8gigs of ram and a ati 6950 gpu, but to the problem your having, did you install your video card drivers? as in your not using windows stock drivers?&lt;/p&gt;</comment>
                            <comment id="13961" author="ezekielelin" created="Fri, 26 Oct 2012 15:31:23 +0200"  >&lt;p&gt;Have you tried a superflat world? Does the FPS issues transfer with worlds? If you close a world and reload it does it remain or reset?&lt;/p&gt;</comment>
