I think the problem here is people can't run this mod with their potatoes:
Fix: Get a better PC
Calamity is only going to take more and more memory from now on.
this is quite sad, though. Because it will eventually lead people into abandoning Calamity for a bunch of smaller mods. Maybe authors can revise the content of the mod and think, if they can omit something? Some redundant armorsets, artifacts, etc. Making mod bigger, adding stuff is great, but it might be wise to keep it in some limits. Now, in my modpack, Calamity is 120mb on itself, while the second-on-size mode Thorium is just 35 (more than 3 times smaller). I know, Thorium is not that filled-to-the-top with content, but it is also very big. There should be some ways to compact and make Calamity more small and optimized, I would say, it is now more and more necessary. Otherwise, it will soon be a stand-alone mod, like some others.
Also, don't forget, there is still 4GB limitation. My PC is far more powerful, than Terraria and all mods need, but they cannot use it anyway.
