I have noticed the with chunk lag has returned. I am sure I have the terminology wrong. I am referring to the lag where the chunk is just a transparent hole in the ground or there is a giant hole in the world that you cannot cross through. I am running the latest Fastcraft 1.12 using Forge #1277 for 1.7.10. At first I thought it could be one of the plethora of mods I have installed so I pulled all of the mods out of the game except Forge and Fastcraft and the issue still occurred. So as an opposite test I put all of the mods back and removed Fastcraft. Then I generated a new world and the issue was non existent. The world I generated was using the Biomes O plenty generator.
Any idea what causes this or could this possibly be a bug in Fastcraft?
Basic info;
Running Minecraft 1.7.10 with Forge #1277
Standard MC resource pack (Default textures)
NO OPTIFINE, NO GLSL, Default game renderer
Java 8 Update #25 64-bit (JDK version, if it matters)
Windows 7 64-bit
6Gb of RAM allocated (I normally run Sphax 256x)
I can provide more information later, I am currently at work. I am not sure what other information would be needed though.
