though i am on a good mac... i admit i get alot of lag... whenever it rains i just see the chat say "lag!!!!" and when i fall then i never respawn and then it will be too laggy to jump... i think it is unfair that we have all this lag preventing us from doing courses... it looks like 1000 people are saying "LAG" (not really 1000!) but you know how many....

 

This should probably be in suggestions o.O
I support though. You can get optifine and turn rain off, but most people won't do it.
