            <title>[MC-2991] Massive Framerate Drop From 1.4.2 to 1.4.4 [EDIT: FIXED]</title>
                <link>https://bugs.mojang.com/browse/MC-2991</link>
                <project id="10400" key="MC">Minecraft: Java Edition</project>
                    <description>&lt;p&gt;EDIT: Problem was easily resolved by updating graphics card drivers. Fault was with NVidia, not Mojang. My apologies!&lt;/p&gt;

&lt;p&gt;During 1.4.2, I ran both the vanilla client and server .exe on my laptop without any issues. Minecraft ran at a solid 60fps throughout, and my friends were able to connect to the server with little problems, even on max settings.&lt;br/&gt;
Ever since the 1.4.4 client and server update, however, both myself and a frequent user of my server have been experiencing extreme framerate drops in-game, peaking at around 10fps. I haven&apos;t changed any of my settings, merely updated the game in-client and simply replaced the server .exe as I would after any update. Chunks load slowly, lighting glitches horribly (chests covered in shadows when they&apos;re 2 blocks away from a torch/glowstone) and the game is unplayable overall.&lt;br/&gt;
It would be most appreciated if a solution was provided as quickly as you can manage!&lt;br/&gt;
Thank you for your time,&lt;br/&gt;
