Whenever I try to play, these lag spikes keep occuring in a timespan of almost 5 seconds. Yes I have a lot of mods, but this only started happening today and only when I add this mod, before I was able to play with the same amount of mods and even with shaders, I tried everything possible to lighten a bit the machine (cleared cache, junk files, closed useless apps). Here it is the modlist:
Version of Advanced Rocketry
Have you verified this is an issue in the latest unstable build
Version of LibVulpes
Version of Minecraft
Does this occur without other mods installed
VisualVM
