my computer isnt the best cpu out there, its about 3-4 years old and it wont run minecraft on fullscreen at max 30fps, i have no gaming computer, i tried recreating my .minecraft folder, i tried everything i could think of but keep getting nothing.

whenever i try launching ANY type of 1.7.2 optifine it just says java exeption and reopens the launcher. forge on the other hand just simply does not open. so i cant use mods, and i cant use optifine. what else am i supposed to do? i tried installing hack clients with optifine built in yet all i get is the hacks. i need help desperately.


please, please, PLEASE help me.
