I started playing the new Oceanblock mod pack, but I have been having FPS issues.
Looking at f3 shows only 4gb of ram has been dedicated to minecraft, so I changed Ram Allocation in the FTB app and Minecraft Launcher to 10gb, but still it only has 4gb dedicated to it.
Looking around in the instance.json file reveals this

"minMemory": 4096,
"recMemory": 6144,
"memory": 10368,

And for some reason the game never goes above 4gb of ram being used, even though I want it to go higher for better FPS (changing these values doesn't do anything and when I reopen the file it is undone)
So what do I do now?
