Minecraft Forums

I am playing single player 1.6.4 with about 50 mods. I count 35 Minecraft says 47.

Recently I started getting block breaking lag, (I break the block. It disappears, reappears then breaks) also the mobs began to move slowly and like robots.

I tried removing the mods that updated just before this happened with no luck.

I created another world with all the same mods and settings. No lag.

Is there a fix for this?
