Get rid of your mac thats the best way to remove the lag.If you want to remove all frames per second lag than buy a custom build with good parts.
No, because the funny thing is Blockland is much smoother in performance on my Mac compared to my slow PC.
Also, Macs can't run games well.
You can't play games in a 800x600 micro window are you handicappedAlso there is no lag at all, stop playing on a toaster
