So I'm walking in void pretty much and it takes a while for the chunks to load.
I'm using the pixpack extreme, Forge 11.15.1.1722, Optifine 1.8.9_HD_U_H3
Same problem also on minecraft that is not running off the pixelmon launcher.
my performance settings:
Smooth FPS: Off
Smooth World: On
Fast Render: Off
Fast Math: Off
Chunk Updates: 5
Dynamic Updates: ON
Lazy Chunk Loading: Off
My Render Distance is set to 24
Changing these doesn't do much.
I also allocated 8GB of memory for Java.
I doubt that my Rig is too slow to handle this because I'm not having these issues with vanilla minecraft.
