Recommended Specs

I am definitely not rich enough to test this modpack on a variety of different hardware configurations, but here are the specs of my system and the performance I observed.

CPU: AMD Ryzen 5 3550H

GPU: GTX 1050 (Laptop)

RAM: 32GB DDR4 3200 SODIMM (15GB Allocated to Minecraft)

Assuming modpack's default settings:

Standing in one spot (like in a base): 50-60 fps

Exploring: 30-45 fps

If you encounter performance issues, disabling the shaders and lowering render distance is probably your best bet.
