[What is the system requirements for Hexxit?]

So how do I fix the lag spikes?

[What is the system requirements for Hexxit?]

I just downloaded Hexxit on my computer. I played it for a few minutes so I can see if it runs smoothly.

It runs smoothly for a while then it has random lag spikes.

 

I have 4.00 GB (I'm hoping to get 8.00GB soon)

64-bit Operating System

Intel Core i5

 

This does not occur on vanilla Minecraft.

 

Thanks in advance.
