(i'm not going to have an info prefix on this unless an admin wants me to add it) Ok, tip if you are using the fastcraft mod, please inform with ANY crash-report to ANY mod author or on MYM that you are using fastcraft, as fastcraft can be uncontrolable and most likely caused the crash most of the time.
Fastcraft made things worse for me than without :I. The time I used it the only thing it did was freezing my mc when I tabbed out (and when tabbing back in giving me 1-2 fps) + give me stuttering at random intervals (without having tabbed out).
I just saw you live in chicago. Every time I hear that name I have to think about: (pg 18 game) Spoiler It was my first ps3 game and was the game that made me a gamer.
Well i use fastcraft and got from 50fps to 115fps so iam happy with fastcraft. The only thing that i dont like are the chunks that dont load fast enough, because if i wear my sash (cant live without XD) iam faster than the chunks load :/ Idk if its my computer or the server :/
