Minecraft: Please help!

[sidas]

Hello gyus!

I get error with mod on Minecraft:

http://minemoding.com/simple-physics-mod-for-minecraft-1-3-1/

When I download it, Minecraft started a little bit lagging, so can I fix that lagg? Thanks for answers

what are the specs of the system you are running it on? Adding physics will stress teh processor more, so I am thinking that is the source of your lag.
