      Hello. I am experiencing a sudden drop in FPS and spike in memory usage when I run on an amplified world or in the Nether. I modified the JVM arguments to use 10G ram thinking that would help. It did, but only a little. I am running an i7-4790S with 12gb RAM, and a Geforce 1650 graphics card. I would not think that this would be a big problem with pretty good specs, but also when I hit F3 below my version of Java, it only shows 512 MB of memory. When I load my world, it will run normally for about 1.5-2 minutes. Then, the FPS will tank and it will lag severely and memory usage will spike. If you could please take a look at this issue it would be much appreciated. Thank you!
