I have an 8g 64-bit laptop, and when I play vanilla minecraft with 64-bit java, I get high fps. But, every modpack is super laggy! When i switch to 32-bit java the modpacks run smoothly, but vanilla minecraft gets low fps. The Problem is that i have to play hexxit on 64 bit because i need to allocate more than 1 gb of ram. But on 64 Bit its super laggy in contrast to 32 bit.
I have a 64 Bit System
I need help. I tried everything. I love the modpack and i would like to keep playing it.
Thank you
ps.: sorry for my bad english
